Etymology: Paralichthys: Greek, para = the side of + Greek, ichthys = fish + Greek, suffix, oides = similar to (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; oceanodromous (Ref. 51243); depth range 0 - 183 m (Ref. 2850). Subtropical; 48°N - 24°N

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 152 cm TL male/unsexed; (Ref. 2850); max. published weight: 33.0 kg (Ref. 9330); max. reported age: 30 years (Ref. 33520)
Lives mostly on sandy bottoms. Common beyond surf line, also in bays and estuaries. Occurs from near shore to 183 m depth. Feeds during the day (Ref. 9643) on fishes and squids, often well off the bottom. An important sport and commercial fish. Also caught with trammel nets (Ref. 9330). Marketed as fresh fillet (Ref. 9330). Adults migrate to shallower waters to spawn (Ref. 9643). Has very sharp teeth and is known to bite if handled (Ref. 13513).
Distinct pairing (Ref. 205).
