a freshwater lobster that runs the riverbed like a tiny armored warlord.
means a small freshwater crustacean resembling a miniature lobster, with claws, a segmented body, and a taste for hiding under rocks in streams and rivers.
from A delightful mistranslation. The word comes from Old French 'crevice' (also 'escrevisse'), itself from a Germanic root related to 'crab' — a cousin of the word that gives us 'crab' in English. When English borrowed it, the final '-vis' sound got mangled by folk reasoning into 'fish,' since the creature lived in water and looked vaguely fishy to landlubbers. So 'crayfish' isn't really a fish at all — it's a crab that got renamed by a misheard syllable. The variant 'crawfish' carries the same fishy confusion.
