lugworm (n.)

c. 1600, from lug, probably a Celtic word (the first recorded use is in a Cornwall context) unrelated to lug (n.) or lug (v.) + worm. But OED suggests connection with lug (v.) on the notion of "heavy, clumsy."

1. marine worms having a row of tufted gills along each side of the back; often used for fishing bait
