Velociraptor

In 1993, a film called Jurassic Park was released that thrust the Velociraptor into the forefront of our collective Dinosaur fascination. Unfortunately... its depiction was pretty darn wrong. Granted, that wasn't wholly the fault of the movie-makers, because one of the primary physical characteristics of the Velociraptor wasn't even discovered until several years after the film's release. But the other major discrepancy... yeah, that one is probably on them.

There are two species of Velociraptor, and both lived in what is now Central Asia. In 1998, a forelimb from one specimen was found that contained some interesting features. There are marks in the bone known as quill knobs. This revelation points to the fact that Velociraptors definitely had feathers. Velociraptors could not fly, but they probably used their feathers for maneuverability, display, and for temperature control. And guess what? They were probably warm blooded.

The other physical trait that the movie got wrong? The size. You see, Velociraptors probably weighed no more than 30lbs, and had a height of about 3 feet. They did at least have those large, terrifying claws, which they used to attack and kill their prey, and one of their favorite meals was the Protoceratops. Velociraptors lived during the late Cretaceous period.

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...

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...

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!
