goatfish

noun

Etymology: From goat + fish. The Mullidae sense is because of the fish's beard (as it were) seeming like a goat's beard (a goatee). The chimera sense is because the mythical beast is half goat and half fish.

1. Any of the family Mullidae of brightly coloured fish with two barbels on the chin.
2. Alternative spelling of goat-fish (“mythical beast”).
