[7], Using mitochondrial DNA, a phylogenetic tree of the hammerhead sharks showed the winghead shark as its most basal member. Another cool thing about them is they’re the only shark with different looking heads (sexual dimorphism) between the genders.

[32] Nevertheless, at up to 1.5 m (5 ft) in length and with highly specialized requirements, very few private aquarists have the experience and resources necessary to maintain a bonnethead in captivity. They seem to be most closely related to the scalloped hammerhead (Sphyrna lewini), and their head shape is very similar.
They also have the largest nostrils of all hammerheads (in proportion to their size). These sharks include great white sharks, tiger sharks, and bull sharks. 1 Synopsis 2 Color Regions 3 Base Stats, Controls, and Abilities 4 Notes/Trivia An open-water voyager, the Great Hammerhead, despite it's size, is no true threat to any survivor unless provoked.
