Adults feed on hydroids, worms, mollusks, and brittle stars (Ref. 6885). Marketed frozen and eaten fried, microwaved and baked (Ref. 9988).
Each individual spawns from 8 to 11 batches (Ref. 39301). Spawning occurs primarily in shallow water but for large females spawning may take place in waters to a depth of around 50 m (Ref. 119537). Undergoes spawning and feeding migration (Ref. 119537).
