Biologia     Glossario (es. epibenthic)

A common species that inhabits mangroves and silty, rocky areas; occasionally found in rubble reef areas. Only single individuals were observed; many individuals found scattered over a small area (Ref. 420). Found primarily in lower estuaries, usually in mangroves. This is the species of the genus that is found farthest inland. Feeds on small invertebrates (Ref. 12693).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Genital papilla, of male varying from lightly to heavily pigmented and terminating to side of anal spine. Female genital papilla lightly pigmented and truncate, terminating well before anal spine (Ref. 420). Benthic spawner (Ref. 32023).
