Short description Morfología | Morfometría

Vértebra: 125 - 137. Vomerine teeth are biserial and diverging anteriorly with the posterior most 3 to 4 teeth forming a single row (Ref. 37816).

Biología     Glosario (por ej. epibenthic)

Fairly common inhabitant of reef flats where it is usually encountered in shallow tidal pools. Feeds on crustaceans, small fishes and octopi (Ref. 89972). Often in shipwrecks; usually in pairs or small aggregations, and shares habitat with other morays (Ref. 48635). Also common in sheltered reefs (Ref 90102).
