Max length : 20.5 cm TL macho/indeterminado; (Ref. 102462); common length : 12.0 cm TL macho/indeterminado; (Ref. 5217); peso máx. publicado: 177.96 g (Ref. 102462)
Espinhos dorsais (total) : 0; Raios dorsais (total) : 55 - 60; Espinhos anais: 0; Raios anais : 40 - 44. Pectorals either vestigial or reduced to 1-2 rudimentary rays (Ref. 36453).
Found more abundantly on shallow soft bottoms of brackish estuaries or hypersaline lagoons. Enters freshwaters at least to an elevation of 10 m. Inhabits rivers and creeks and probably feeds on aquatic insects and crustaceans (Ref. 36880).
