Inhabits sandy and muddy bottoms in bays (Ref. 43239). The life span of this species is one year: fast growing before its reproductive period, with adults measuring within 30-40 cm and 100-400 g, it gets thinner towards the end of its life. It feeds on shrimps, fish and crabs. Female individuals carries about 60,000 eggs (ellipsoidal in shape, 1.97-1.42 mm average diameter) with some lobes of transparent membrane projecting from its end (Ref. 81825).
