| Biology: | Inhabit shallow inner continental shelf waters, including bays and inlets (Ref. 6390). For their first few years, they live mainly where seagrasses (Zostera species, Posidonia creeks. Small juveniles favor water depths from 2 m to 20 m. Adults inhabit more exposed waters along coastal beaches and reef areas (Ref. 27008, 27667), sometimes to depths as great as 200 m. Spawn in offshore waters from late summer to winter (Ref. 6390). Juveniles feed on benthic amphipods and other crustaceans. As they grow larger, their diet expands to include polychaete worms, mollusks and peanut worms (Sipuncula) (Ref. 27008, 27667). Oviparous (Ref. 205). This premium quality fish obtains a high price (Ref. 6205). | |||
