Скачать или смотреть Hippopotamus | The Hippopotamus is a large semi-aquatic mammal that is found wallowing in the rivers

. Despite its appearance, the Hippopotamus is an animal that is actually thought to be most closely related to Whales as the two are thought to have had a common ancestor that existed roughly 54 million years ago. Also known as the Common Hippopotamus, it is one of two Hippo species that are found on the African continent with the other being the solitary and forest-dwelling Pygmy Hippopotamus which is only found in western Africa and is now Critically Endangered. Although the Common Hippopotamus remains an abundant and widespread animal throughout its current range, numbers are reportedly declining due to both hunting and habitat loss.
The Hippopotamus has an enormous grey barrel-shaped body that can measure up to five meters in length and weigh more than four tonnes, and which is held up by short and stocky legs. One of the Hippopotamus’s most distinctive features is their enormous jaws which contain two long canine teeth (tusks) which can grow up to 50 cm long and are used for fighting. Due to the fact that the Hippopotamus is an animal that spends most of its life resting in the water, they have a number of excellent adaptations to aid their semi-aquatic lifestyle including four webbed toes on each foot that help with swimming and walking on slippery banks, and the eyes, ears and nostrils of the Hippopotamus are situated on the top of its head. This means that when the Hippopotamus’s body is immersed in the water, they are still able to see, hear and breath whilst keeping cool in the hot sun.
