Sengi

Also known as Elephant Shrews, Sengis are small mammals belonging to four genuses within the Macroscelididae Family. They are not actually related to true shrews all that closely, for they belong to a different Family and Order entirely. Because Elephant Shrew is a bit of a misnomer, biologists have been using the name "Sengi," which is their Bantu name. Interestingly, molecular research in recent years show that Sengis could be more closely related to the Elephant and they are to the Shrew.

Short Eared Sengis
Sengis are found only in Africa. Depending on the species, they live in savannahs and scrublands, as well as dense forests. Some species are diurnal, while others are active during both the day and night. Sengis are carnivores eat a variety of invertebrates, including worms and spiders. A few species will also supplement their invertebrate diet with fruits and other plant matter. They themselves are preyed upon by a wide variety of larger creatures, and as such, they must always be alert. Eagles, Lizards, and Snakes all hunt Sengis. When they have spotted a predator, they slap their tails on the ground as a warning signal.

Sengis mate for life, and many species breed continuously over the course of the year, though their little size is only one. While they are not a very vocal group, Sengis have exceptional sense of smell, sight, and hearing. Some will built complicated track systems throughout the undergrowth in order to both hunt and escape from predators.

Thanks to Heather for the suggestion!

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a...

Four!

For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!

Banggai Cardinalfish

Pterapogon kauderni The Banggai Cardinalfish is a small tropical fish that is becoming very rare in the wild, even though it has been successfully bred in captivity. You will only find these small, 3in long fish around the Banggai Islands of Indonesia. They are the only members of their genus, and you can tell them apart from other Cardinalfish by their three-striped bodies, tasseled first dorsal fin, long second dorsal, and their deep-forked tail fins. Banggai Cardinalfish are diurnal and live in small groups of about a dozen members. They are opportunistic feeders who dine on whatever smaller plants and animals they can find. Courtship and mating is pretty interesting for these guys-- females are the ones who initiate. They isolate a male and the pair will perform various courtship rituals before spawning. The Cardinalfish are mouthbrooders, which means that the males take the fertilized eggs (up to 90 of them) into their mouths and incubate them for up to 30 days. During t...
