HippoWorlds is a reference site dedicated entirely to the hippopotamus — one of the most fascinating and misunderstood animals on the planet.
Since 2014, we’ve been compiling accurate, research-backed information about hippo biology, behavior, habitat, diet, reproduction, and conservation status. Whether you’re a student, a wildlife enthusiast, or just curious after watching a nature documentary, you’ll find clear and reliable answers here.
Today, hippos face serious threats: habitat loss, poaching, and climate change have pushed both the common hippopotamus and the pygmy hippopotamus toward vulnerable and endangered status. We believe that understanding these animals is the first step toward caring about their future.
HippoWorlds covers all two living species — the common hippopotamus (Hippopotamus amphibius) and the pygmy hippo (Choeropsis liberiensis) — as well as extinct species and the latest research from conservation organizations worldwide.
