Hippopotami

Hippopotami, commonly known as hippos, are large, semi-aquatic mammals native to sub-Saharan Africa. The word "hippopotamus" originates from the ancient Greek for "river horse." There are two extant species: the common hippopotamus (Hippopotamus amphibius) and the smaller pygmy hippopotamus (Choeropsis liberiensis).

These herbivorous animals spend most of their day submerged in rivers, lakes, and swamps, emerging at night to graze on grasses. Their skin is thick and mostly hairless, and they secrete a reddish, oily fluid often referred to as "blood sweat," which acts as a sunscreen and antiseptic. Hippos are social creatures, often found in groups called pods, typically led by a dominant male.

Despite their herbivorous diet, hippos are considered one of the most dangerous animals in Africa due to their unpredictable nature and immense strength. They possess large canine tusks and powerful jaws, capable of inflicting serious injury. Their semi-aquatic lifestyle is crucial for thermoregulation, as they are susceptible to overheating and sunburn on land.

The common hippopotamus is the third-largest land mammal after elephants and rhinoceroses. Pygmy hippos, on the other hand, are more solitary and prefer denser forest environments. Both species face threats from habitat loss and poaching, leading to conservation efforts to protect their populations.
