The hippopotamus (Hippopotamus amphibius) (/ ˌ h ɪ p ə ˈ p ɒ t ə m ə s /; pl.: hippopotamuses; often shortened to hippo (pl.: hippos), further qualified as the common hippopotamus, Nile hippopotamus and river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa.
Cleaning symbiosis is well-known among marine fish, where some small species of cleaner fish, notably wrasses but also species in other genera, are specialised to feed almost exclusively by cleaning larger fish and other marine animals. Other cleaning symbioses exist between birds and mammals, and in other groups.
The word hippoglossus is derived from the Greek ἵππος (hippos), meaning "horse", and γλῶσσα (glōssa), meaning "tongue" - a reference to the shape of the fish. Species [ edit ]
It's believed that the male was protecting one of the hippo calves that was in the group (also called a pod or a bloat). Hippos don't actually swim, instead they walk along the bottom of the water ...
Pygmy hippos are now classified as endangered, the alliance said, with possibly less than 3,000 individuals remaining in their native habitat. Zoo draws thousands of visitors
A 2015 study suggests that hippo dung provides nutrients from terrestrial material for fish and aquatic invertebrates. [58] Because of their size and their habit of taking the same paths to feed, hippos can have a significant impact on the land across which they walk, both by keeping the land clear of vegetation and depressing the ground.
[16] [17] A hippo normally spends up to five hours a day grazing. They normally feed only on land, though occasional consumption of aquatic vegetation has been observed. [14] By contrast, cetaceans are all carnivores, feeding on fish and marine invertebrates, with some species feeding on larger mammals and birds (such as seals and penguins). [18]
The pygmy hippo is herbivorous, feeding on ferns, broad-leaved plants, grasses, and fruits it finds in the forests. A rare nocturnal forest creature, the pygmy hippopotamus is a difficult animal to study in the wild. Pygmy hippos were unknown outside West Africa until the 19th century.
