Biology     Glossary (e.g. epibenthic)

Common in shallow waters. Usually observed in pairs or large groups. Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205). Called a cunning fish since it can nibble the bait from a hook without taking the hook into its mouth. The juvenile Thalassoma sanctaehelenae has been observed cleaning the cunningfish of its parasites (Ref. 5288).
