IUCN Status : Vulnerable

The Hippopotamus is the third heaviest of all land animals, behind the Elephant and White Rhino. A large males can weight as much at 10,000lbs (4,535kg)! Even at birth they are huge; a newborn weighs around 100lbs (45kg).

Hippopotamuses are one of the most dangerous land mammals in Africa. Males are especially territorial and use their long tusks for fighting over land and harems of females. Threatened Hippos can attack and kill humans, and are able to run at speeds of up to 14mph (30kph).

Hippopotamus Teeth
Hippopotamuses have skin that needs to constantly stay moist. In order to accomplish this they remain in water for as long as possible, sometimes up to 16 hours a day. Adults can hold their breath for around 5 minutes (though longer times have also been observed in necessary situations), while newborns can last only about half a minute. Hippos also secrete a weird, reddish colored mucus that keeps the skin moist and helps to prevent sunburn. It is also thought that this mucus might help to prevent skin infections.

At night, the Hippos leave the water to graze. Interestingly, they eat very little compared to their body weight, only around 1-1.5%.

Illegal hunting and habitat loss have hurt Hippopotamus numbers, and overall their population is decreasing. They are protected in many areas, but coverage and enforcement is spotty.

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!

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
