A group of hippopotamuses is called a bloat, but they may also be called a crash, a herd, a huddle, a pod, a school, or a thunder.
Few animals have accumulated as many collective nouns as the hippopotamus, and it’s not hard to see why: these massive, water-loving mammals inspire imagery ranging from their bulky bodies to the thunderous sound of a group crashing through water.
What Is a Group of Hippopotamuses Called?
The most widely cited and commonly used term today is a bloat of hippopotamuses, a fairly blunt reference to their size and rounded, water-buoyed bodies. Numerous alternates persist as well: crash, herd, huddle, pod, school, and thunder, each highlighting a different facet of hippo life.
Where Did the Name Come From?
“Bloat” is the most literal of the bunch, simply describing the hippo’s enormous, rounded silhouette, especially as seen floating at the water’s surface. “Crash” and “thunder” both evoke the raw physical force of a hippo group moving on land or charging through water, hippos may look sluggish, but they’re capable of surprising speed and aggression when threatened. “Pod” and “school” borrow directly from aquatic-animal terminology, fitting given how much time hippos spend submerged, while “herd” is the more generic, catch-all term applied to large group mammals broadly. “Huddle” likely reflects how hippos cluster tightly together in water to stay cool and protected. Unlike single-origin terms, this collection reflects a genuinely divided, informal tradition, no one name ever fully won out.
