Sinocalliopteryx

Sinocalliopteryx gigas
Sinocalliopteryx certainly has a mouthful of a name! It actually translates to "Chinese Beautiful Feather," as they had feathers, and their fossils were uncovered in the Yixian Formation in north east China. It is a relatively new species, in terms of discovery, and was only first described in 2007.

Sinocalliopteryx lived around 130-125 million years ago, during the Early Cretaceous. They are the largest known members of their entire family, measuring nearly 8ft long. These guys were bipedal, and had powerful hind legs and arms that were longer than most others in their family. They also had "proto-feathers," which were thin, hairlike feathers. (I imagine something that looked similar to the feathers on a Cassowary).

New research has come out that suggests Sinocalliopteryx hunted much like a modern cat does. Fossil evidence shows that they flying creatures, including small aerial Dinosaurs. They probably stalked these animals quietly, hiding in the underbrush. Then, when the right moment hit, they would jump up into the air with their powerful hind legs and snatch on to the prey. This theory is still controversial, as fossils are only able to tell us so much about behavior. However, the leg anatomy, coupled with the presence of flying creatures in the digestive system, makes for a compelling argument.

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...
