Fun Facts about Hippopotamus

DiD YOU KNOW? The hippopotamus, also known as the "river horse," is the third-largest land mammal, after elephants and white rhinoceroses. They can weigh up to 1,500-1,800 kg (3,307-3,968 lbs) and can grow up to 4 meters (13 ft) in length. Despite their large size, hippos are fast swimmers and can reach speeds of up to 48 km/h (30 mph) in the water. They are also excellent swimmers, and can hold their breath for up to five minutes underwater. Hippos are herbivores and can eat up to 150 lbs of vegetation per day. Hippos are known for their aggressive nature and are considered one of the most dangerous animals in Africa. They secrete a red oily substance from their skin, which acts as a natural sunscreen and moisturizer. Hippos are social animals and live in groups called "schools" or "herds." The hippo's closest living relative is the whale, and genetic studies have shown that they share a common ancestor that lived around 55 million years ago. Hippos are considered to be a vulnerable species, with populations declining due to hunting and habitat loss.
