Beluga Whale

Belugas Whales (Delphinapterus leucas) are very iconic whales with their all white adult bodies, short beaks, absent dorsal fins, and large "melon" foreheads. They are found in the waters of the Arctic, and migrate to sub-artic waters to stay away from freezing ice. Belugas can grow to sizes of up to 20ft (6.1m).

Did you know that Beluga Whales are not always white? As calves they are a darker gray color, which gradually lightens as they age. They will reach their full white color by around age 5. Females gestate for 14 months, and a newborn calf can measure 4-6ft (1.4m) long. Calves remain with their mothers for up to two years, and feed off of milk that is 28% fat in order to grow and maintain warmth in the cold waters.

Beluga Pod
Belugas are extremely social creatures. They live in pods that communicate through a variety of whistles, mimics, and clicks. They are also rather unique among Cetaceans in that they have non-fused neck vertebrae, which allows them to turn their heads and even make facial expressions!

Beluga Whales hunt using echolocation, a process that involves sending out clicks that then bounce off potential prey and echo back to the whale. The Beluga's large forehead contains a melon, which helps to amplify and focus these clicks. They feed on fish, worms and crustaceans, and consume 50-60lbs (22.6-27kg) a day.

Burmese Peacock

Polyplectron bicalcaratum Burmese Peacocks are also referred to as Grey Peacock-Pheasants, which is probably a more apt name, as they are not actually Peacocks... though they do belong to the same family. At any rate, they share some physical resemblances to Peacocks- most notably the eyes on their tail feathers. Burmese Peacocks are the national birds of Myanmar, which was called Burma until 1989, though some still refer to it as such. The birds live in several other Southeast Asian countries as well, and are divided into four subspecies. The species as a whole is listed as being of Least Concern , because they have a large range and population size. It unfortunately appears that they may be declining in number, but it is a slow descent that does not yet meet the vulnerability thresholds. The birds are listed under CITES Appendix II, because they can be kept in captivity and grabbing individuals from the wild could become problematic for the species. IUCN Stat...

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!
