Scalloped hammerhead shark (Sphyrna lewini)
Distribution: Worldwide, warm temperate to tropical regions.
Habitat: Inshore and offshore. Mostly taken in coastal and pelagic fisheries.
Pectoral fin description
The dorsal surface is light brown
or greyish-brown in color with a
dull, smooth texture. The fin is
generally short and broad from
leading edge to trailing edge and
is a narowly rounded at the apex.
Dark patch is visible on the
ventral surface, concentrated at
the apex.
Similar Species: Blacktip, spinner and white shark pectoral fins also have a dark patch concentrated at the
apex on the ventral side, but are not as short from the base to the apex or as broad from leading edge to
trailing edge as the scalloped hammerhead. Smooth hammerhead pectoral fins are similar in shape and
color, but lack the dark patch concentrated at the apex on the ventral surface.
