River Horse


Hippos are the third largest land mammal species on Earth, after elephants and white rhinos. Hippopotamuses are found in Africa. The name Hippopotamus means ‘river horse’. Their skin color varies from brown to grayish purple, and they’re almost completely hairless. Their ivory canine teeth grow continuously, and reach 20 inches in length. Hippopotamuses have short legs, a HUGE mouth and a body shaped like a barrel. A male Hippo is called a bull, and a female hippos is called a cow. These mammals are good swimmers. They have membranes that are between their toes that turn their feet into flippers, and fat beneath their skin helps them float in rivers and lakes. Adult Hippos can hold their breath underwater for up to six minutes.

The Mammal that lays eggs!!


The platypus is a warm blooded, egg laying mammal with webbed feet and fine, waterproof fur. Unlike other mammals, the platypus lays eggs, typically two eggs, which cling to the female‚Äôs fur on her belly. The Female Platypus holds the eggs between her body and tail to keep them warm. The mom Platypus feed their babies by these two glands on their belly that releases milk and it oozes into the mothers fur, which the babies slurp off. Babies are born with teeth but they fall off when they get older. Platypuses live near freshwater rivers or lakes and create burrows for shelter and protection. They feed on freshwater animals and fish such as shrimp, crayfish, mayflies, mussels, earthworms, and dragonflies. Platypuses spend around 12 hours every day looking for food because, they must consume at least one quarter of its body weight each day. These mammals swim with their eyes, ears and nostrils shut, and can only stay underwater for a few minutes. Did you know that the Male Platypus is one of the few venomous mammals… And he can transport poison, causing really really bad pain to humans, through a spur on his hind foot. Here is a cool video I found of these guys swimming and hunting for food.

Tallest Mammal in the World!

A Giraffe is the tallest mammal in the world!! The Giraffes average height is around 17-20 feet tall. Other animals in the savannah use these tall mammals as watchtowers or observation posts for predators. You will probably never see a Giraffe sleep, because they get so little of it. They just sleep for a few minutes at a time, and usually only get about 30 minutes total in a single day. Giraffes can go without drinking water longer then a camel!! They can go for days without water, which actually protects them from some of the dangers that more water dependent animals have. When being attacked giraffes use their large powerful hooves to kick at its enemy. Newborn giraffe calves begin their lives by falling 6 feet to the ground. A Calve is about 6 feet tall at birth. A Giraffe is able to clean its ears with its own tongue.
