Descrição breve
Chaves de identificação | Morfologia | Morfometria
Juveniles associate with drifting seaweed. Plankton feeder (Ref. 12114, 12115). Viviparous (Ref. 34817).
Males established territories ranging from 12 to 70 sq. m; initiated courtship when females approached the territories; lateral display, rushing and turning movements were frequently observed during courtship. Mating pair formed about 30 min before copulation; the pair ascended to 1.5-2.0 m above bottom then males suddenly coiled around the body of females to copulate.
