板鰓亜鋼(サメとエイ類) (sharks and rays) > Carcharhiniformes (Ground sharks) > Sphyrnidae (Hammerhead, bonnethead, or scoophead sharks)
Etymology: Sphyrna: Probable misspelling of sphyra (Gr.), hammer, referring to their hammer-shaped heads (See ETYFish); tiburo: From tiburon, Spanish for shark, a name given by 16th- and 17th-century navigators to one or more large species of shark (See ETYFish).

Front of head semicircular in outline. No other hammerhead has front of head in semicircle. (Ref. 26938).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
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). Also found in mangrove areas (Ref. 138854). Spends night time hours on shallow grass flats, searching for nocturnally active invertebrate prey, moves into deeper water during the day (Ref. 27549). Adults feed mainly on crustaceans, also on bivalves, octopi, and small fish. However, this is the first shark species to demonstrate omnivorous digestive strategy (Ref. 118574). It has been shown through digestability analyses that bonnetheads have enzymes that can digest seagrass organic matter with at least moderate efficiency (Ref. 118574). 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.
