Antiguan Racer

Alsophis antiguae
The Antiguan Racer is believed to be the rarest snake in the entire world. It is so rare, in fact, that in 1995 there were only 50 left! The Racers grow to lengths of around 1m, prefer to live in shady areas, and are completely harmless to humans.

Unfortunately, humans were farm from harmless toward the Racer population, which dwindled due to human involvement and introduced predators. When colonists arrived on the island of Antigua, they inadvertently brought Black Rats along with them. The Rats multiplied quickly, feeding on crops and Racer eggs, among other things. The farmers, wanting to get rid of the rats, introduced Asian Mongooses. Unfortunately, the Mongooses also fed on Snakes, and not just their eggs. It wasn't long before the Antiguan Racer was completely extinct on the island of Antigua itself. They continued to survive in small numbers on the Mongoose free Great Bird Island.

Though they were free from Mongooses on Great Bird Island, the snakes still had to worry about Rats, natural disasters (like hurricanes and droughts), and a loss of genetic diversity due to inbreeding. In 1995, when the population hit 50 individuals, a successful effort was made to eradicate all Rats from Great Bird.

The population doubled with the loss of the Rats, but it was discovered that the island was too small to sustain a larger snake population. Efforts are ongoing to remove Rats and Mongooses from other offshore islands, so that the snakes can be reintroduced there as well.

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
