Raios dorsais (total) : 15 - 17; Raios anais : 14 - 15; Vértebras: 30 - 35. Males with a less prominent notch in dorsal fin; no irregular black spots on sides of body; a gray cast superimposed on gold body and gray fins. Head wedged shaped; upturned lips; proportionately larger head and orbit. Tendency to fewer lateral scales, predorsal scales and vertebrae. Male with fins larger, especially dorsal and anal fins; greater prepelvic length, head and body depths; first 6 anal-fin rays small folding into fleshy dermal pocket supported by 7th ray; dorsal fin notched, first 4-5 rays separated slightly from the rest.

Biologia     Glossário (p.ex. epibenthic)

An experimental fish. Pinnate diatoms (largely benthic), filamentous algae indicate that this species grazes rocks and plant surfaces along or near the bottom (Ref. 29410).

Ciclo de vida ou comportamento de acasalamento Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

Viviparous. Gestation lasts for about 55 to 60 days. Produces 10-15, rarely 20, young. Matures approximately at the fifth month.
