Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 10; Rayons mous dorsaux (Total): 12; Épines anales 3; Rayons mous anaux: 7 - 8. Body pale brown dorsally with several vertical dark brown bars, becoming white ventrally; dorsal fin dusky with longitudinal yellow lines; pectoral, pelvic and anal fins dusky; caudal fin dusky with small yellow blotches (Ref. 13608). Preopercle has spines radiating from 2 centers (Ref. 26938).

Biologie     Glossaire (ex. epibenthic)

Inhabits bays, coastal grassy areas and shallow banks. Solitary (Ref. 26340) and retreats into shelter when frightened (Ref. 9710). Neither opercular spine nor anterolateral glandular grooves with venom gland is present (Ref. 57406). Synchronously hermaphroditic. Popular as a pan fish despite its small size.

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Simultaenous hermaphrodite. The gonad contains ovarian and testicular tissue separated by a thin basement membrane, with no means of internal self-fertilization.
