Barnard's Lanternfish

Symbolophorus barnardi
Today's animal is one of those mysterious deep-sea dwellers that we don't often see, despite their massive range and huge population. It is called the Barnard's Lanternfish , and it gets its name from the bioluminescent photophores that allow its head, underside, and tail to light up!

Studies have shown that this Lanternfish, and other members of its family, make up more than half the biomass down in the deep sea, and they live in ocean waters across the globe! Today's species in particular is a small little guy that can be found throughout the Southern Hemisphere, living at depths of up to 3,000ft, though they tend to come up closer to the surface during the night, and can be found in waters as shallow as 350ft.

If the fish can be found in (relatively) shallow waters, why bother diving so far down during the daytime? This behavior takes place in order to avoid becoming someone's dinner. Barnard's Lanternfish are a great food source for larger ocean-dwelling animals, so they dive down to avoid predation when those animals are doing most of their hunting. The Lanternfish then come closer to the surface so that they themselves can feed on the plankton that live there.

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
