Walrus

Odobenus rosmarus are large, Arctic Pinnipeds that can grow in excess of 3,000lb and reach lengths of 10-12 feet, with the males being slightly larger than the females. They are known for their whiskered faces and enormous tusks, which are found on both sexes. These tusks can grow up to 39in, and are actually just long canine teeth.

Walrus tusks are useful for a number of purposes. Males use them to fight for and protect mates and territory. Males and Females use their tusk to break ice, and maneuver themselves out of water. Their whiskers also serve an important purpose: detecting shellfish meals on the sea floor. Clams and mussels make up a large portion of their diet.

Walruses are very social creatures, and live in large herds year round. During non-breeding times, separate herds form for males and females. These herds also tend to migrate, moving from beaches to ice flows. As far as reproduction goes, females have 15-16 month gestation periods, and calves can weigh over 150lbs at birth!

Because Walruses are so massively large, their only non-human predators are Orcas and Polar Bears. Walruses were hunted for their tusks, hides, and oil for many, many years. Currently only a handful of native groups are allowed to hunt Walruses, and the numbers are carefully monitored.

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!

10 Years?!

My goodness! It's been 6 years since I went on hiatus, and now more than 10 years since AaD was born, and what a world we've moved in to! Animal a Day is coming back- but in the meantime, check us out on Facebook, for your daily dose of #BIRDNEWS
