Biology     Glossary (e.g. epibenthic)

Facultative air-breathing in the genus (Ref. 126274); Commonly found on sand bottom, also on mud bottom. Occurs in intertidal areas and up to 142 m depth (Ref. 2850). Feeds on shrimps and other crustaceans (Ref. 4925). Aquarium observations indicate that this is nocturnal (Ref. 2850).
