	Hammerhead shark - Wikipedia, the free encyclopedia
		The eight species of hammerhead range from 2–6 m long, and all species have projections on both sides of the head that give it a resemblance to a flattened hammer.
		It is probable that the hammerheads evolved during the late Eocene, Oligocene or early Miocene.
		Because the hammerhead has sensors along its entire head, one theory for why the hammerhead has a hammer-shaped head is to provide a greater area for sensors to scan the bottom of the seafloor for fish, crustaceans, or other food items to eat.

		The eight species of hammerhead range from 2–6 m long, and all species have projections on both sides of the head that give it a resemblance to a flattened hammer.
		The hammerheads seem closely related to the Carcharhinid sharks that evolved during the mid- (From 63 million to 2 million years ago) Tertiary, but the teeth of hammerheads resemble those of some Carcharhinids, making it difficult to be certain when the hammerheads first appeared.
		It is probable that the hammerheads evolved during the late (From 58 million to 40 million years ago; presence of modern mammals) Eocene, (From 40 million to 25 million years ago; appearance of sabertoothed cats) Oligocene or early (From 25 million to 13 million years ago; appearance of grazing mammals) Miocene.

	Hammerhead Sharks
		Hammerheads are found in almost all of the tropical and warmer temperate waters of the world.
		The scalloped hammerhead, one of the most commonly seen shark by divers in Hawaii, has four lobes on the leading edge of the "hammer", and generally reaches between 5 to 10 feet long.
		Hammerheads are especially vulnerable due to their schooling behavior and the predictability of the schools' locations.

		Long-winged and long-tailed, the hammerhead, or hammerkop (as it is called in Africa), may reach a body length of 20 in.
		Hammerheads reside singly, in pairs, or in small flocks, near water and seldom far from trees, in the forks of which they build intricate domed nests, some 3 to 6 ft (91.5–183 cm) or more in diameter.
		Hammerheads are classified in the phylum Chordata, subphylum Vertebrata, class Aves, order Ciconiiformes, family Scopidae.

		The hammerhead shark is rare in the waters off San Diego and northern Baja California.
		It also extends the shark's sensory systems: the eyes are placed far apart, improving its field of vision; the ampullae of Lorenzini and lateral line have a larger surface area, increasing their sensitivity.
		Hammerheads are efficient predators and feed on bony fishes, other sharks, crustaceans, and especially stingrays that they can find buried in the sand.

	Shark facts and photos with Hawaiian Islands commentary by Rico Leffanta
		Scalloped Hammerhead sharks are notorious for swishing about, doing corkscrews, etc., but no one knows for certain whether that is just shark aerobics, or part of a mating ritual which has changed very little since it was first described by the Marquis de Sade.
		Stomachs of adult scalloped hammerhead sharks, in Hawaii, reveal an appetite for bony fish - especially needle fish, eels, squid, octopus, shrimp and lobster, a diet which clearly establishes hammerhead sharks are using their heads to find food, much the same as French pigs use their snouts to find truffles.
		In shark culture, the scalloped hammerhead shark is immediately identifiable by five dents in the front rim of its skull.

	Hammerhead Sharks
		As their name suggests, hammerhead sharks have wide, flattened heads that are reminiscent of hammers.
		Because hammerhead sharks have one eye and one nostril at each end of their heads, they have a broader range of vision and sense of smell than most (if not all) oceanic predators.

		As its name implies, the dual EL-34, 25 watt Hammerhead is designed to deliver the rough and tumble tone of a big amp on '10' in a sensibly-powered and compact package.
		And unlike some well-known 'master volume' circuits of the past, the Hammerhead succeeds in righteously pumping out true harmonic distortion at variable volume settings rather than relying on a few extra capacitors or a push/pull circuit to merely imitate gain and output tube distortion.
		Built with just one duet of matched EL-34's and two 12AX7 pre-amp tubes, the Hammerhead is designed with an ultrapure signal path that allows every subtle (and not-so-subtle) nuance of your guitar to be heard and savored.

		This is true for some sharks, such as the hammerhead, but not all sharks live in a school, or a group.
		Hammerhead's eyes are three feet apart from each other which gives it a wide range of vision.
		At this time I do not know exactly how far apart the eyes of a hammerhead shark are, but I feel that it actually depends on which of the five spieces of hammerhead, and the size of the hammerhead that determine the length beteen the eyes.
