Hippos and Ecosystems

Hippos, despite being non-native, play a crucial role in nutrient distribution within ecosystems by stirring up sediment and providing food for microorganisms. A fascinating study highlights how these creatures may be filling ecological gaps left by extinct large mammals, such as giant llamas and rhino-like species, which thrived in South America tens of thousands of years ago. The conversation also humorously touches on the initial misconceptions about the size of these ancient animals, revealing the surprising reality of their scale.
