Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 3; Mjukstrålar i ryggfenan (totalt): 26-29; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 23 - 26. Tall, with a small mouth and plate like scales (Ref. 35388). Three faint irregular broad dark bars on body; a narrow pale transverse band on chin; small light blue spots on upper half of body and median fins, and irregular short lines ventrally (Ref. 13442).

Biologi     Ordlista (t.ex. epibenthic)

Inhabits bays, harbors, lagoons, and seaward reefs (Ref. 9710). May drift with young at surface among Sargassum (Ref. 9710). Usually solitary or in small groups (Ref. 9710). Feeds on benthic invertebrates like mollusks and crustaceans (Ref. 4727). Oviparous (Ref. 205). Consumed mostly fresh, smoked, and dried salted. The flesh is of excellent quality. Because it is resistant to capture, it proliferates and competes for food with other species (Ref. 5377).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Adults guard the embryos nested in sand which hatched in about two days (Ref. 9778).
