Abstract: Kaneohe Bay, Oahu, is a pupping ground for the scalloped hammerhead
shark, Sphyrna lewini, the pups being most abundant between April and
October. While in the bay, the pups stay in the most turbid areas by day and move
out at night to reef areas where they feed on reef fishes and crustaceans. The pups
spend a maximum of three to four months in the bay and then apparently leave
nearshore areas. The total number of pups passing through Kaneohe Bay may be
as high as 10,000 per year.
Adult hammerheads are present inshore also between April and October. They
apparently move in for delivery and breeding. Squid beaks in their stomachs indicate
that the adults are pelagic the rest of the year-possibly living below the
surface layers.
