Fearful Owl

Nesasio solomonensis Say hello to the Fearful Owl, a very large owl that sports a dark face and very distinctive white eyebrows. They are very similar in appearance to the Whekau , or Laughing Owl. And if nothing is done about the downward trend they are on, they might just be extinct like the Whekau as well! The Fearful Owl is a tropical owl found in lowland forests of Papua New Guinea and the Solomon Islands. They are very rarely seen, but they do have their own  Solomon Islands postage stamp ! These Raptors are a top predator in their range, most commonly feeding on the Northern Common Cuscus, along with other Cuscus species. Cuscus hunting is one of the reasons that the Fearful Owls are now Vulnerable-- their main prey is being over-hunting by man, giving them fewer things to eat. Another reason for their decline is the growth of the logging industry. Fearful Owls need the forests in order to survive, and without them they have no where to go. It is estimated that only 6,00

Greater Long-tailed Hamster

Tscherskia triton Did you know that there are literally dozens of species of Hamsters, not just the ones that we keep as pets? Today's animal is one of the wild ones. It is considered to be a "Rat-like Hamster" and is actually considered to be quite the nuisance! Meet the Greater Long-tailed Hamster , a rodent species that is found in China, North and South Korea, and parts of eastern Russia. They live in open areas near water, including grasslands, marshlands, and agricultural fields. The Hamsters that live near crops and rice fields are considered to be pests, as they will eagerly go after the grains and seeds. All members of the species, regardless of what they eat, stockpile food for the winter, sometimes up to 20lbs of it! Greater Long-tailed Hamsters have a very short lifespan-- only about a year. But during that year they do their very best to carry on their genetic line. They can produce three litters of up to 10 offspring in only a few months time! IUCN

Milky Stork

Mycteria cinerea Today's animal is the Milky Stork, a tall bird with a milky-white body and black flight feathers. They can be found in the marshes, mudflats, and mangroves in Indonesia, Cambodia, and Malaysia. They breed in large, multi-species colonies during the dry season, building nests that can be several feet in diameter. Milky Storks were historically found throughout Southeast Asia, but they are now locally extinct in several countries and are on the sharp decline in their remaining range. It is estimated that there are only 5,000 of them left in the wild. What are the threats behind this population plummet? Hunting and habitat loss. Land development for agriculture has destroyed many of the mangrove nesting sites that the birds rely on, and they continue to be hunted for food and feathers (eggs are also taken). It has been illegal to trade Milky Storks internationally since 1987, but domestic exchanges still occur. The birds do appear in some protected areas, an

Chocolate Chip Sea Star

Protoreaster nodosus It's no wonder how the Chocolate Chip Sea Star got its name. These tropical echinoderms have creamy, brownish bodies topped with dark brown tubercles all over the top, making them resemble the popular cookie! You can find Chocolate Chip Sea Stars in the shallow waters of the Indian and Pacific Oceans, hanging out in sandy beds and near coral reefs. Sea Stars have no eyes, so they must find they prey using their sense of smell. Chocolate Chips aren't picky about what they eat, so their meals can range from live sea aponges, to coral, to the waste of other animals. When they find some food, they actually push their stomach outside of their mouth, engulf the meal, and then bring it back inside their body! The species has the ability to reproduce both sexually and asexually. Sexual reproduction is done externally-- the eggs and sperm are released into the water at the same time, where they mix and fertilize. The Sea Stars can also reproduce asexually

Western Jackdaw

Corvus monedula Meet the Western Jackdaw. These mostly-black birds are the second smallest members of their genus, and are one of the littlest species in the entire Corvid family. Western Jackdaws can be found across Europe, as well as in North Africa and Central Asia. Most of the populations are residents, though some in the north and east migrate. They are a very adaptable species , and can be found in habitats that range from sea cliffs, to meadows, to urban building ledges! There are actually four different subspecies of Western Jackdaw. All of them differ by location and by their head and neck coloration. All four have dark grey/black bodies, but the size and lightness of the crown varies. Western Jackdaws Western Jackdaws are incredibly social, and can be found in large flocks that number into the hundreds. These flocks function with a strict hierarchy, and birds will fight and create threat displays to assert dominance. The birds are also very social when it comes to

Cookiecutter Shark

Isistius brasiliensis Today's animal is no joke! Though they only grow to be about a foot and a half long, they can do some really amazing looking damage to much larger sea creatures!  Cookiecutter Sharks  get their name from their relatively unique jaws and what they do with them. They have large, powerful sucking lips, a row of narrow teeth on the top, and a row of much larger, knife-like teeth on the bottom. Like other sharks, they regularly replace their teeth. However, instead of losing a single bottom tooth at a time, they replace the entire row at once! Old teeth are swallowed, giving the Cookiecutters a good source of Calcium. Cookiecutter Sharks attract their much larger prey using bioluminescent photophores (which grow bright green). The bigger sea creatures will go after the shark, but in a twist they will become the actual prey. The Cookiecutter will latch on with its mouth, spin its body around, and remove a perfectly circular chunk of flesh (just like a cookie c


Proailurus lemanensis Meet Proailurus , a cat-like creature from the early Miocene that is shrouded in taxonomic mystery. Its fossils have been found in Europe and Asia, dating back 25-20million years. Proailurus looked quite a bit like modern Fossas-- they had long bodies and short arms. They also possessed the same binocular vision as modern cats, and a similar dental structure. These prehistoric cats most likely climbed trees and stalked their from their as present-day leopards do. But is Proailurus a true feline ? Or is it even more than that? Many believe that Proailurus is the common ancestor for all cats, but it may also be a common ancestor for other creatures as well. A recent genetic study has placed Proailurus into the Feloidea superfamily, which also encompasses the Hyenas and Viverrids (like the aforementioned Fossa). Additional fossils and genetic studies may shed more light on this in the future. Status :  Extinct for 20 million years Location :   Fossils foun

Lesser Electric Ray

Narcine bancroftii The Lesser Electric Ray is a smaller species of ray that is found in the tropical and subtropical waters of the Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. They are very slow, sluggish swimmers, and are most commonly found in shallow, sandy waters. As the name suggests, Lesser Electric Rays are able to create a small electric charge, thanks to two organs in front of their eyes. They are capable of producing up to 37volts, and use their skill to hunt prey and to defend themselves. The Lesser Electric Ray is in trouble. The species is listed as Critically Endangered , due to high amounts of bycatch capture over years and years. Even if a captured Ray is set free, damage may have already been done, as pregnant captured females will often abort their offspring. Lesser Electric Rays are ovoviviparous, and can have very long gestational periods due to the ability to delay embryonic growth. Terminated pregnancies due to bycatch can have a huge impact

Moon Wrasse

Thalassoma lunare Today we're going to learn all about the beautifully colored Moon Wrasse, which gets its name from the crescent moon shaped pattern on its tail. They are also sometimes referred to as Lunar Wrasses and Cruscent Wrasses. In the wild, Moon Wrasses can be found in the tropical waters of the Indian and Pacific Oceans. They prefer shallow , oxygen rich waters that are no deeper than about 60ft, and are most common in and around Coral Reefs. They are carnivorous, and feed on small invertebrates like crabs and starfish. Moon Wrasses actually change color as they age, starting out with blueish bodies and black spots, and then becoming green, pink, and blue over time (with those bright yellow crescent tails!)  These fish also have the fun distinction of being protogynous hermaphrodites . This means that they all start out as female, and that some will change and become male depending on different environmental triggers. This process only takes 10 days to complete!

Island Fox

Urocyon littoralis Meet the Island Fox, one of the smallest foxes in North America, and also one of the most endangered. These small Canines are found exclusively on six of the eight Channel Islands off of the coast of California, and are the only carnivores found only in that state. Did you know that there are actually six different subspecies of Island Fox? One for each of the six islands that they inhabit? Around 10-16,000 years ago , Grey Foxes from the mainland made their way over the islands. Once there, the population evolved over time to be smaller in size (an example of Insular Dwarfism). They are around 1/3 smaller than their cousins. The Foxes are incredibly important to the Channel Island habitat because they keep rodent populations down, they keep bird populations stable (by feeding on the small mammals that feed on birds), and they help to disperse the seeds of many native island plants. The foxes are omnivores that hunt during both the day and night, due to the

Ivory Gull

Pagophila eburnea The Ivory Gull is a small to medium sized Gull that spends most of its time at the high Arctic latitudes. They migrate only very short distances (it is rare for them to enter temperate zones), and are usually found within close vicinity of pack ice. They are the only members of their genus, Pagophila . Ivory Gulls are appropriately colored for a snowy, winter-year-round environment. Their feathers are completely white, the bill is a bluish grey, and their black legs and eyes are the only dark shades on them. As juveniles they have a bit of black flecking on the feathers, and it takes about two years to develop the snow-white plumage. These seabirds are both hunters and scavengers. They snatch up crustaceans, fish, rodents, and small birds, but they will also feed on corpses, including those of larger animals like seal and caribou. Other things that these opportunistic feeders will chow down on? The feces and placentas of other animals! Mmm. Ivory Gulls will

Brown Leaf Chameleon

Brookesia superciliaris The Brown Leaf Chameleon belongs to the same genus as some of the smallest reptiles in the entire world ( B. micra   is the tiniest Chameleon on record). Like the other members of the genus, today's species lives on the island of Madagascar, and it also happens to be rather small. The full head to tail length of the Brown Leaf Chameleon is only a few inches. The small size certainly helps with their defensive camouflage. You see, Brown Leaf Chameleons resemble curled up, dead leaves ! They can  change color, but shades or brown and green are the most common, as those are the colors of the dead leaves that they forage in. Brown Leaf Chameleons spend most of their time on the forest floor, where they hunt for insects. If they themselves feel threatened by a predator, they roll up and lie very still, hiding in with their surroundings. Camouflage isn't the only thing interesting about these tiny reptiles. They also have a neat little mating ritual

Broad-bodied Chaser

The Broad-bodied Chaser is a very distinctive Dragonfly that is found in several locations across Europe, Central Asia, and the Middle East. They are typically found around areas of still water, and fly from April until September, though are most common from May to June. Both the male and female Chasers have very flat, broad abdomens (hence the name). Both sexes have yellows spots running down the length of the abdomen, but the primary color differs. Males develop a pale blue pruinescence, while females have abdomens that are golden brown. Libellula depressa (male) Female Males of the species are very territorial, and will fight other males that enter their airspace. If a female enters the territory, the male will often approach and grapple them, mating in mid-flight. The coupling is very brief, and afterwards the female will search for a suitable place to lay her eggs. She deposits them by flying over water with submerged vegetation, and dipping her abdomen in. It will


Coccosteus There are several different types of fish swimming around today. We have the Ray-finned Fish, The Cartilaginous Fish, the Jawless Fish, and the awesome prehistoric Lobe-finned Fish. But once upon a time we have a 5th group-- the Placoderms, or Armored Fish. Placoderms once swam in waters all over the world, but the entire class died out during the late Devonian period around 360 million years ago. These scary looking armor plated fish are probably best known from their largest class member-- Dunkleosteus . But keep in mind that not all Placoderms where over 20ft long. Like the other fish classes, they had members of all sizes! Coccosteus is one genus of fish on the opposite side of the size spectrum. These little guys were only around 16in at the longest. They still possessed the same armored heads as their larger cousins, and they also had a  modified jaw that let them open their moths extra wide in order to eat larger prey. Coccosteus fossils have been sound in

Galapagos Penguin

Spheniscus mendiculus Did you know that there is only one species of Penguin that lives north of the Equator? Today's animal is the very one! The Galapagos Penguin is endemic to its namesake islands which lie smack dab on the Equator, giving the birds their unique distinction! Galapagos Penguins are small little guys, standing only about 18in tall when full grown. They have black heads and bodies, with white bellies and white horse-shoe-shaped lines that run from their eye to chin. Living in such a warm climate can be rough for a bird from an Antarctic Family! In order to stay cool the penguins spend the daytime in the colder current waters, and then they come ashore at night. They also pant, hold their flippers out to let heat out of their bodies, and stand hunched over their bare feet. Galapagos Penguins don't' have a set breeding season -- they tend to reproduce whenever the food supply is the most abundant. pairs will mate for life, which helps when you have


Kentrosaurus aethiopicus Meet the Kentrosaurus, a member of the Stegosaurus family whose fossils have been found exclusively in the African country of Tanzania. Kentrosaurus lived during the Late Jurassic, between 155 and 150 million years ago. They were smaller members of the Stegosauridae family, and only measured around 15ft from head to tail. Kentrosaurus had hind legs that were longer than their front legs, which means they fed primarily on low lying vegetation. These Dinosaurs were herbivores, possibly traveled in herds, and were most likely not very intelligent (very small brain size compared to body size). This Dinosaur had a double row of bony plates that ran from the head to the mid back. No one is especially sure what the plates were used for-- temperature control and for mating displays are two theories. Where the plates end, a double row of long spikes begins. There were most likely used for defensive purposes. The name "Kentrosaurus" is actually inspir

Malabar Tree Toad

Pedostibes tuberculosus The Malabar Tree Toad is a very small, slender species that is found only in the forests around the Western Ghats in India. They are also referred to as the Warty Asian Tree Toad. If you couldn't guess from the name, these Toads live in the trees that are usually close to a body of water. They are found on the ground as well, as that is where they breed and lay their eggs, but they ascend into the trees during the night time. Malabar Tree Toads are small little guys, and measure only around 1in in length! (Yes, that is a human fingernail in the picture.. for a size reference.) Females are slightly larger than the males. They can be identified by their warty brown bodies and the black and white bands that run down their sides. The Malabar Tree Toad is currently listed as Endangered , and its population is on the decline. Its main threat is habitat loss due to the logging and farming industries. They are found within several protected refuges, and a

Spotted Redshank

Tringa erythropus The Spotted Redshank is quite the little traveler . These birds spend their summers in Scandinavia and in parts of Siberia. When the autumn comes, they head south. Some go as close as the British Isles or the Mediterranean, while others make it all the way to Southeast Asia and even Australia! These migrations can start as early as late June, and will take months to complete with several stopover points. Spotted Redshanks are wading waterbirds that can be found in marshes, forests, and wetland regions in whatever country they happen to be in at the time. They feed on very small water dwelling creatures, usually insects and their larvae, though they will take small vertebrates on occasion as well. Spotted Redshanks typically wade in order to feed, but they will also swim into deeper water and upend themselves like ducks do. The population of Spotted Redshanks is currently stable, but that may not always be the case. Habitat degradation is happening in many of

Golden-crested Mynah

Ampeliceps coronatus The Golden-crested Mynah is a smallish Starling that can be found throughout a large range in South and Southeast Asia. They have also been introduced to a handful of islands as well. Their preferred habitats lowland, subtropical forests. These birds are very appropriately named-- they have bright yellow crowns on their heads, and darker feathers over the rest of their bodies. Like many other Mynahs, the Golden-cresteds are able to  mimic other sounds . They can even recreate human voices! The word Mynah itself actually derives from a Sanskrit word meaning "joyful," which is turn has a root word that means "bubbles." "Bubbling with joy" is a pretty apt description of these active, talkative birds. Golden-crested Mynahs are omnivores that feed mostly on fruits and small insects, though they will go after some small vertebrates as well. They live in small flocks, pairs often remain together for several years, and they have a li


Protylopus It's pretty amazing to think about the origins of some of the animals that we know so well. When you picture a camel, you probably envision a large, humped mammal with cloven, padded feet. But did you know that their earliest discovered ancestor was comparatively tiny, had no humps, and had four toes ? Meet Protylopus, the oldest known camel . These guys lived during the Eocene, around 45-40 million years ago. They were absolutely diminutive by modern camel standards. They were barely two feet tall, and about the same measurement in length. Protylopus probably weighed no more than around 50lbs. Think of them as about the size of a medium sized dog! There are five different species within the Protylopus genus, with P. petersoni  being the type species. All lived in what is now North America. Based on their teeth, they most likely fed on leaves and other soft plants, and it is possible that they even stood up on their hind legs to feed, as their front legs are shor


Eolophus roseicapilla The Galah, or Rose-breasted Cockatoo, is a very wide-spread Cockatoo that cane be found throughout Australia . Their name is derived from the Yuwaalaraay word   that is used to describe the birds. Galahs can be found in just about every corner of the continent, living in habitats that range from urban cities to woodlands, to open fields. They feed on different seeds, leaves, and grains, as well as on insects. As adults, Galahs have bright pink heads and chests, with a lighter pink crest and grey wings. They are even sometimes referred to as "Pink and Greys." The only real difference between males and females is the eye color-- males have dark eyes, while the females have reddish-brown eyes. Galahs live in flicks that can number from a few dozen to a few hundred. They stick together while foraging, but  will often go slightly off on their own while nesting. Males perform a dance, complete with stick waving and head bobs, in order to attract a ma

Morgan Horse

Morgan Colt The Morgan Horse is one of the earliest horse breeds developed in the United States, dating back to the late 18th century. They are small, strong horses that often toe the line between being of horse size (over 14.2 hands) and pony size (under 14.2 hands). They come in a wide variety of colors, though black, chestnut, and bay are the most common. The breed dates back to 1789, when a Massachusetts businessman named Justin Morgan bought a young colt that he named "Figure." Figure was known for his expressive nature, athleticism, gentile nature, and his endurance. When Morgan died, Figure was passed to different owners, and was eventually renamed Justin Morgan after his first master. He became the foundation sire for an entire new breed, and was able to pass on all of his defining traits to his offspring The breed took off, and by the Civil War it had become a very popular mount for the cavalry, because of their ability to work under pressure and because of

Blue Whale

Balaenoptera musculus Happy World Oceans Day everybody! And what animal could represent the oceans better than the largest one in them? Meet the astonishing Blue Whale, the biggest creatures to have ever lived! Blue Whales can reach lengths of up to 100ft, and weigh nearly 400,000lbs. That is incredible! Their hearts are the size of a small car, and their tongues can weigh as much as an elephant ! In fact, right at birth they are already one of the largest animals on the planet. A newborn can measure over 25ft long and weigh 3 tons. (They also will grow 200lbs every single day!) It is amazing to think that an animal so massive has a diet that is based exclusively on tiny little crustaceans called Krill. During the Arctic summers, they can consume up to 4tons of Krill in a single day! They feed by gulping a huge amount of water into their mouths, expanding their mouths and belly out in the process. They then push the Krill up into their baleen plates and strain the water out,

Delicate Mouse

Mus tenellus Today's creature is one of those animals that not very much is written about. Maybe it is due to their small size? Maybe specific mouse species just aren't distinguishable enough from one another? Well, we're going to try and learn as much about the Delicate Mouse as possible anyway (though it may not be much). Because who couldn't be interested in a tiny creature with a name like that? The Delicate Mouse is one of many, many species found within the Mus  genus. What makes them (sort of) stand out is their location-- Mice are divided into five different location-based subgenera, and the Delicate Mice belong to the group that is exclusively found in Sub-Saharan Africa . They have been recorded in Somalia, Kenya, Tanzania, Sudan, and Ethiopia, and were first described in 1903. Within their range, the Delicate Mice live in dry savanna habitats that are at low elevations. They feed on different grains and grasses, and they themselves serve as prey for a

Tufted Puffin

Fratercula cirrhata Meet the Tufted Puffin , a seabird from the Northern Pacific that is the largest of the Puffin species. These birds are best identified by their breeding plumage, which shows up only during the summer months. Their normally yellow/orange bills and feet turn bright red, their black faces change to white, and both sexes grow large yellow feather tufts. The Tufted Puffins breed in large colonies -- some of them have literally tens of thousands of pairs! They build very crude nests, placing a soft lining of feathers and plants in a rock crevice, or in a burrows scratched out with their feet. Only one egg is laid at a time, and the chick is incubated and cared for by both parents. Tufted Puffins are much better in the water than they are on land. They are able to dive after their fishy food, and they typically eat their meals while still under water. The exception to this is when they have offspring to take care of. A Puffin parent can hold as many as 20 fish

Catahoula Leopard Dog

Red Merle Catahoula Leopard Dog The Catahoula Leopard Dog (also known as the Catahoula Cur) is an American dog breed that has an ancestry dating back hundreds of years. Many believe that they are the result of crossings between native bred dogs and the sight-hounds and molossers brought over by European explorers in the 16th century. An alternative theory is that their origin may be more recent-- when 19th century French Settlers brought over Beaucerons those dogs bred with the native stock. Regardless of their exact date of origin (heck, both theories could even be true!), a mixing of European and North American bloodlines certainly created this interesting looking breed, which is named after a Parish in Louisiana and was designated as their State Dog in 1979. Catahoula Leopard Dogs were bred to be working dogs , and their most common purposes are for tracking and hunting, and also for livestock herding. They also serve as search and rescue dogs as as drug snigging dogs. Be

Giant Pangasuis

Pangasius sanitwongsei Meet the Giant Pangasuis, who certainly is one monster of a fish! These dwellers of the Mekong and Chao Phraya River basins can grow nearly 10ft long, and they are second in Catfish size only to the Mekong Giant Catfish. The species is also sometimes referred to as the Paroon Shark and the Chao Phraya Giant Catfish. In the wild, the Giant Panasuis is a migratory creature, moving upstream in order to spawn just before the monsoon season hits. And when it comes to feeding they are technically omnivores, though they tend to consume meat more often then not. Adults live in the large rivers, while juveniles are found in smaller tributaries. Unfortunately.. like many large fish in developed areas, they are becoming very, very rare. The Giant Pangasuis is now listed as  Critically Endangered . Overfishing, habitat loss, pollution, and capture for the (doomed) pet trade have all been factors for their decline. (I say "doomed" because even though hundre

Cape Lobster

Homarinus capensis The Cape Lobster is a species of Crustacean that lives off the coast of South Africa. The main things to know about these guys is that they are incredibly elusive. From 1792 to 1992 only fourteen specimens were collected. In 1992 the discovery of one of these rare Lobsters prompted a surge in discovery, and another 20 or so have been identified since... though most have been as parts regurgitated by fish. Why are Cape Lobsters so hard to find? South Africa's waters have been more explored, studied, and cataloged than any other country's on the continent, why is the story here? Well, the Cape Lobsters are very small, especially when compared to the lobsters we normally think of. Their entire length is only around 4in, and their main carapace tops out around 2. This keeps them out of most Lobster traps. Another cause for their elusiveness is that very little is known about their habitat and biology, and much of the existing information has been prove

Variegated Fairywren

Malurus lamberti (male and females) I just love the look of today's animal-- the Variegated Fairywren . Their name means "having streaks or patches of different colors," which is very true for the males. They sport black chests, bright chestnut patches on the shoulders, and brilliant blue heads. (Females are shades of grey). You can find the Variegated Fairywren (and most other Fairywrens) in Australia , where they are the most common and widespread members of their genus. There are four different subspecies, each found in a different location across the continent. These little birds are incredibly active, spending large chunks of their day hopping about on the ground and in low foliage in search of food. Their long tails help them to balance while bouncing around, searching for insects to eat. The social structure of the Variegated Fairywren is rather interesting. After breeding (which can occur at any time of the year but is most frequent in Spring and Summer)


Pleurosaurus A long, long time ago we talked about the Tuatara -- the last living reptiles that belong to an incredibly ancient Order that dates to the Mesozoic. Though only two species of Tuatara survive today, there were once several other different Sphenodontians roaming the planet, and today's animal is one of them. Meet Pleurosaurus, a very snake like reptile that lived an aquatic lifestyle in what are now the lakes of Western Europe. Pleurosaurus was a small little guy, measuring only about 2ft long, and its entire body was streamlined for marine hunting efficiency. They had incredibly thin bodies , very short appendages, and a long, powerful tail. They most likely swam in an undulating motion, as Sea Snakes do, and probably didn't use their small arms much at all. Pleurosaurus also had nostrils that were placed closer to their eyes than to their snout. This adaptation probably allowed them to hunt fish easier in the shallow lakes where they lived. Fossils of t
