Short description Morfología | Morfometría

Front of head semicircular in outline. No other hammerhead has front of head in semicircle. (Ref. 26938).

Biología     Glosario (por ej. epibenthic)

Found on the continental and insular shelves, on inshore and coastal areas, over mud and sand bottoms, also on coral reefs. Often occur in shallow water including estuaries, shallow bays and over coral reefs (Ref. 9987). Spends night time hours on shallow grass flats, searching for nocturnally active invertebrate prey, moves into deeper water during the day (Ref. 27549). Feed mainly on crustaceans, also on bivalves, octopi, and small fish. Viviparous, with 6 to 9 young per litter. Size at birth about 35 to 40 cm. Not territorial. Always occurs in small groups. Considerable sexual segregation occurs. Shows diel rhythm of activity. Utilized for human consumption and processed for fishmeal.
