Siamangs are the largest of the Gibbons, apes of the family Hylobatidae that live in tropical environments of the Eastern Hemisphere. Siamangs can measure a meter from head to rump, and weigh up to 30lbs. They can be found in the rainforests of Malaysia and Indonesia.

Siamangs are black in color, and have a sac on their throats that allows them to greatly amplify sound. They are able to produce the loudest sounds of any Gibbon. There is slight sexual dimorphism, with males being larger than the females. Like all apes, Siamangs do not have tails, and their bodies are more upright oriented.

When on the ground, Siamangs are more or less bipedal. When in the trees however (which is about 80% of the time) they move by brachiation, which is hand over hand swinging. During this movement, they are able to carry things with their feet. Their arm span can be as large as 1.5m.

One of the most interesting facts about the Siamang is that it is a species that forms monogamous bonds. This is rare for an ape. They live in family groups comprised of that pair and up to four children. They forage for food together (mostly leaves and fruits, but sometimes insects and birds) and groom each other. Siamangs have a gestation period of 7.5 months, and the young are born quite helpless. They will not be weaned for two years and after that they continue to stay with the parents for a bit longer.

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


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!


The Binturong ( Arctictis binturong ) also has an equally awesome alternate common name, the Bearcat! However, it really isn't much of a bear OR a cat. While it is true that it is part of the Feliforma suborder, it is not a member of family Felidae. Binturongs are a part of their own family, Viverridae, which is shared with Civets, Linsangs, and Genets. There are six subspecies of Binturong, all of which have slight differences based upon location and habitat. Binturongs range in body size from 60-100cm in length, (not including their tail which has roughly the same length) and weigh between 20 and 30lbs. Binturongs are nocturnal animals native to the rain forests of South East Asia. The species range spans through several countries including China, Malaysia, Indonesia and the Philippines. They are tree dwelling mammals, and have fully prehensile tails that basically double their body length and can be used to cling to the trees or to grasp food. Binturongs are phe
