Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 55 - 60; Espinhos anais: 0; Raios anais moles: 40 - 44. Pectorals either vestigial or reduced to 1-2 rudimentary rays (Ref. 36453).
Body shape (shape guide): short and / or deep.
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).
