Short description
Morfología | Morfometría
Espinas dorsales (total): 0; Radios blandos dorsales (total): 89-106; Espinas anales 0; Radios blandos anales: 73 - 89; Vértebra: 102 - 108. Parietal bones are not connected with each other and are separated by the upper occipital bone throughout their length.
Found under stones in the channel of a river during low tide (Ref. 74969). Largest mature individuals caught measure 21.5-31.5 cm TL (Ref. 74969). Viviparous, with variable number of eggs, 4-131 (Ref. 74969).
Viviparous (Ref. 74969). In this species, only the left ovary is developed (Ref. 74969).
