THE HAMMER-HEADED SHARKS. FAMILY SPHYRNIDAE


Table of Contents

The peculiar hammer-shaped head, with eyes far apart, sufficiently characterizes the Gulf of Maine sharks of this family, which resembles the requiem sharks (p. 36) otherwise. Five species are known in the western Atlantic, all of them tropical-subtropical in nature. Two of these have been reported from our Gulf, but only as strays.
