What is a piscine animal?

Piscivorous

mammals are mammals which primarily eat fish. They are not clearly defined by morphological features, but more often share similar tooth structure. These teeth are strongly recurved

towards the back of the throat, to prevent fish from escaping. Some marine mammals have piscivorous

teeth (such as the seal and some sea lions). Other marine mammals such as dolphins and porpoises have homodont

teeth. These are

comprised of many identical peg-like

structures.
