Subantarctic Fur Seal

Arctocephalus tropicalis
The Subantarctic Fur Seal is one of the smaller Fur Seals, and it is also one of the most "tropically" located. They live closer to the Equator than than other Southern Hemisphere relatives do, though they don't quite make it up to the literal tropics... which makes their species name a little misleading.

As with most seals, there is some difference in size between the males and females. Males tend to grow about 2ft longer than the other sex, and can weight three items as much (300lbs vs. around 100lbs). Both sexes do share a similar look, sporting creamy colored faces and chests. However, males are a dark brown over the rest of their bodies, while females are more grey.

Subantarctic Fur Seal
During the breeding season (which begins around September/October), the males haul ashore and stake out territories that they defend. The females eventually follow, choosing a male's territory to reside in. There, she will give birth to her pup that she got pregnant with the previous year, and will with the resident male about a week or two after. Subantarctic Fur Seals have delayed implantation, so though she may have mated in December, the female will not actually be pregnant until April or May. Pups live with their mothers until the next one is born, and though the males may leave after breeding season ends, the mother/pups groups will always stick close to the rookery in order to nurse. Fun fact: the milk that the mothers give to their pups contains 39% fat, which is a lot compared to the 5ish% in human milk!

Subantarctic Fur Seals were in trouble back in the early 19th century-- they were hunted pretty extensively for their pelts. Luckily, the hunted died down and enough Seals remained to allow the population to rebound. There are now around 300,000 individuals, and they are listed as being of Least Concern.

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!

Binturong

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
