Teleostei (teleosts) > Pleuronectiformes
(Flatfishes) > Paralichthyidae
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; depth range 0 - 40 m (Ref. 26375). Subtropical; 12°S - 54°S
Southwest Atlantic: Brazil. Does not occur in Argentina nor in Uruguay (Ref. 43588).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 100.0 cm TL male/unsexed; (Ref. 26375); common length : 40.0 cm TL male/unsexed; (Ref. 6077); max. published weight: 12.0 kg (Ref. 26375)
soft rays: 52 - 67. Pectoral fins small, about two times head on ocular side, 2.7-3.0 time head on blind side. Pelvic fins about equal in size and shape on both sides. Caudal fin double truncate (Ref. 27363).
Inhabits coastal areas, in bays and estuaries (Ref. 36453). Found over sandy or muddy substrate. Apparently, reproduction occurs during summer in small groups of 3-15 individuals. Adults are solitary. This species is very much appreciated for its taste and high commercial value.
