Sphyrna mokarran (Great hammerhead) [Illustration

A very large hammerhead with a notch at the
centre of head, 1st dorsal very high and curved, 2nd dorsal and
pelvic fins high and with deeply concave rear margins. Colour light
grey or grey-brown above, white below, fins unmarked.
5.5 m TL.
East coast, northern Natal and Mozambique; circumtropical.
Coastal and offshore, often around coral
reefs, from the intertidal to at least 80 m.
Bears 13 to 42
young. Feeds on bony fish, other sharks, rays, and squid.
Considered dangerous, though no attacks recorded here. It
may steal speared fish from divers but is often unagressive when
encountered underwater. Caught by anglers off kwaZulu, and
infrequently by the Natal shark nets.
