the.com/snapping terrapin

means A freshwater turtle known for its powerful hooked jaws and aggressive bite when out of water, as opposed to its milder-mannered aquatic cousins.

from 'Terrapin' comes from an Algonquian word (via languages like Powhatan) for turtle, picked up by English colonists in North America. 'Snapping' is just plain English describing the business end of the animal — its jaws close fast and don't apologize. The two halves of the name come from very different worlds: one borrowed from Indigenous language, the other bluntly descriptive, stitched together by colonists naming what they met in the water.
