A piscivore is a carnivorous animal which eats primarily fish. Piscivorous is equivalent to the Greek-derived word ichthyophagous. Fish were the diet of early tetrapods (amphibians); insectivory came next, then in time reptiles added herbivory. Some animals, such as the sea lion and alligator, are not completely piscivorous, often preying on aquatic invertebrates or land animals in addition to fish, while others, such as the bulldog bat and gharial, are strictly dependent on fish for food. Humans can live on fish-based diets as can their carnivorous domesticated pets, such as dogs and cats. The name "piscivore" is derived from the Latin word for fish, ''piscis''. Some creatures, including cnidarians, octopuses, squid, spiders, sharks, cetaceans, grizzly bears, jaguars, wolves, snakes, turtles, and sea gulls, may have fish as significant if not dominant portions of their diets. ==Examples of extant piscivores== * Aquatic genet * Flat-headed cat * Bulldog bat * Sea lion * Otter shrew * European otter * American mink * Fishing cat * Amazon river dolphin * Giant otter * Bottlenose dolphin * Harbor seal * Osprey * Merganser * Penguin * Bald eagle * Gharial * Yellow-bellied sea snake * African tigerfish * Barracuda * Lemon shark * Fishing spider 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Piscivore」の詳細全文を読む スポンサード リンク
