(Various families in series Eupercaria) > Labridae
Etymology: Semicossyphus: Greek, semi = half + Greek, kossyphos, -ou = a kind of fish (Ref. 45335). More on author: Jenyns.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 100 m (Ref. 11295), usually - m (Ref. ). Tropical; 0°C -
Southeast Pacific: Ecuador to central Peru, and Galapagos Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 70.0 cm TL male/unsexed; (Ref. 11295); max. published weight: 4.0 kg (Ref. 11295)
Caught in both shallow and deep waters. Its strong dentition makes it an opportunistic predator, even of hard-shelled benthos as shown by its stomach contents of coarse calcareous remains and detritus (Ref. 11295).
