What does piscivorous mean?
Piscivorous is an adjective describing an animal that eats fish. It is especially used in biology, ecology, fisheries science, and wildlife descriptions, where it provides a concise way to identify an organism’s feeding habits. The word can describe animals that feed chiefly on fish, such as pike, herons, and some seabirds, as well as species whose diet is entirely fish-based. Its formal register makes it more precise than the everyday expression “fish-eating,” while its Latin-derived formation gives it a distinctive scientific tone. The related noun “piscivore” names an animal that eats fish, and the abstract noun “piscivory” refers to the habit or practice of eating fish. Piscivorous is related in form and meaning to terms such as carnivorous, herbivorous, insectivorous, and omnivorous, but it is more specifically associated with a diet of fish.

Where does piscivorous come from?
The word comes from the Latin adjective piscivorus, formed from piscis, meaning “fish,” and vorare, meaning “to eat.” The English adjective follows this Latin formation, with the suffix -ous producing an adjective. Its English relatives include piscivore, piscivory, and pisciculture, which share the same fish root.
