Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 5; Spine anali: 0; Raggi anali molli: 5; Vertebre: 22. Body light to dark brown, olive or blue dorsally and laterally, light brown ventrally. Tail rings 14, anteriormost 7 mobile, remaining 7 fused; terminal tail rings with dorsal and ventral pairs of posteriorly directed spines; rostrum square in cross section; interpectoral plate absent. 4 pairs dorsolateral body plates; 5 pairs ventrolateral body plates; suborbital shelf convex, obscuring eye from ventral view; deep pits on dorsal surface of head and within interorbital depression absent. Orbit with small scales.
A benthic species found inshore of the continental shelf in muddy, silty and sandy bottoms, usually with seagrass; intertidal to 50 m depth (Ref. 75154). Large numbers of individuals are known to congregate in the shallows of estuaries. The species is capable of burying itself in the sediment and change colors to match the background.
Life cycle and mating behavior
Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve
Spawning occurs as male & female swim from vent to vent, about 1 meter off the bottom, while they release eggs & sperms. The pair separates and each swims away as the eggs begin a pelagic phase.
