Overview

The hippopotamus is a massive semi-aquatic mammal known for spending much of its life in water despite being able to run quickly on land. Although often seen resting calmly, hippos are highly territorial and among the most dangerous animals in Africa. They play an important role in shaping freshwater ecosystems.

Fast Facts

  • One of the heaviest land animals on Earth

  • Can run faster than humans over short distances

Conservation

Hippopotamuses are vital ecosystem engineers in African rivers and wetlands, transporting nutrients from land to water through their daily movements, which supports fish, insects, and aquatic food webs. They are threatened by habitat loss, drought linked to climate change, and illegal hunting for meat and ivory from their teeth, causing population declines in parts of their range. Conservation efforts focus on protected waterways, anti-poaching enforcement, sustainable water management, and community-based conservation to ensure hippos and the ecosystems they sustain can survive.​
