the.com/hookworm

means A parasitic intestinal worm that burrows in through skin (often bare feet), hooks onto the gut wall with its toothed mouth, and feeds on blood.

from A straightforward compound: 'hook,' for the curved, tooth-lined mouthparts the worm uses to anchor itself to the intestinal lining, plus 'worm,' for its wriggling, elongated body. The name is purely descriptive, coined once the parasite's hooked grip was observed under study — no hidden story, just anatomy doing the talking.
