capitan
Synonym discussion
Sense: noun/1
'Capitan' and 'hogfish' refer to the same species (Lachnolaimus maximus), but 'hogfish' is far more common in everyday fishing and restaurant contexts across the Americas. 'Capitan' is used regionally, especially in areas with Spanish-language influence. 'Wrasse' is a broader family name (Labridae) that includes over 600 species worldwide — calling a hogfish simply 'a wrasse' is accurate but loses the specific identity. In a fish market, ask for 'hogfish'; in a biology text, either 'capitan' or 'hogfish' works.
Etymology
'Capitan' comes from Spanish 'capitán' meaning 'captain' or 'chief', likely referring to the fish's large size and the prominent hump on its forehead, which gives it a commanding appearance. The name entered English through American fishing communities that had contact with Spanish-speaking Caribbean and Gulf Coast fishermen.
