Description: The hippopotamus, scientifically known as Hippopotamus amphibius, is a large and robust mammal primarily found in rivers and lakes of sub-Saharan Africa. This animal, which can weigh between 1,500 and 3,200 kilograms, is one of the largest in the world, second only to the elephant. Despite its bulky appearance and mostly herbivorous nature, the hippopotamus is considered one of the most dangerous animals in Africa due to its aggressive temperament and ability to move quickly both on land and in water. Its skin is thick and nearly hairless, allowing it to stay cool in warm climates, and it secretes an oily substance that acts as a sunscreen and antibacterial agent. Hippos are social animals that typically live in groups, known as ‘pods’, which can include 10 to 30 individuals. Their diet mainly consists of grass, and they usually feed at night, as they are nocturnal animals. Despite their size, they are excellent swimmers and spend much of their time submerged in water to regulate their body temperature and protect their skin from the sun. Their behavior and physical characteristics make them a fascinating and essential species for the aquatic ecosystem they inhabit.
