Wisent Bull
Phylum : Chordata
Class : Mammalia
Order : Artiodactyla

Genus : Bison
Species : B. bonasus

Height : 6ft (180cm)
Weight : 2,000lbs (900kg)

IUCN Status : Vulnerable

Also known as the European Bison, the Wisent once had a range that spread across the whole of Europe. Unfortunately, like their American cousins, they were hunted to near extinction. By the end of World War I, Europe's largest land animal had gone completely extinct in the wild, and only 54 individuals were living in captivity.

Captive breeding and reintroduction have saved this species, and there are now around 1,800 free ranging Wisent in Poland, Belarus, Ukraine, and several other Eastern European countries. In 2010, seven individuals, two males and five females, were released in northern Spain, a nod back to the days when the Wisent could be found across the entire continent.

There are unfortunately a few issues that plague the success of the species, one being the lack of genetic diversity. Because all Wisent  are descended from only 12 individuals, they are extremely susceptible to disease, including foot-and-mouth. Another issue is the existence of hybrid American-European Bison herds in the Caucasus Mountains. These hybrids live very close to the reintroduced Wisent, and there are fears that there will be intermingling.

Wisent are actually not all that different from American Bison. They are slightly smaller, and have longer legs but less hair. Wisent also browse, while Bison typically graze for their meals. They live in herds that are not typically family groups, and females give birth to one calf at a time. Wisent can live as long as 25-30 years.

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
