Etymology: "Piscivorus" is a Latin adjective built from two parts: "piscis," meaning fish, and "-vorus," from "vorare," to devour or swallow whole. The second element is the same root that gives English "voracious" and "carnivore," so the word is literally "fish-devouring." Latin formed such compounds freely, and "piscivorus" appears in classical and later Latin texts describing birds and animals that prey on fish. English took the term much later, as a technical word in zoology and ornithology. Naturalists needed precise labels for diet, so they reached back to Latin to describe species like kingfishers, ospreys, and certain fish-eating mammals. The English form is used mainly in scientific writing, where it classifies animals by what they eat rather than by where they live.
