Biology     Glossary (e.g. epibenthic)

This occasionally schooling species is found in inshore sandy and muddy areas. Also found in ecotones near hard bottoms (Ref. 92840). Juveniles found in lower estuaries. Mainly diurnal, this species feeds on small polychaetes, amphipods (corophiids, caprellids), cumaceans and mysids (Ref. 4696). Spawns in summer in shallow waters. Male lures the female into an empty bivalve shell where she lays a portion of eggs. Guarded by the male for 10 days until larvae about 3 mm long. Larvae are pelagic at first. Young fish only start to live at the bottom when 17-18 mm (Ref. 35388).
