The hammarhead shark is perhaps
the most unique of all sharks. It has a large flat rectangular head. They can
be up to 20 feet long and grow up to 1,000lbs in their 30 year lifespan. Their
eyes are set on the edges of its head, which it can use to attack prey. Having
their eyes set so widely gives them an advantage when hunting for prey. They
have a larger visual range than other sharks, making it easier to scan the
ocean. Also, having a wide head allows them to have a larger ampullae of
lorenzini, which is what sharks use to detect the electrical fields of their
prey. This increased sensitiviy allows them to find the foods it likes, even if
they are burried in the sand. There are many types of hammerhead, with the
great hammerhead being the largest, most are relativaly small. Although they
are very defensive and attack when they are bothered, hammerheads are not very
aggressive. In fact, they are generally considered harmless to humans. These
sharks have triangular teeth that are very jagged and like to migrate to cooler
waters in the summers. Generally they like temperate or tropical waters around
the world. They like to eat smaller fish, octopuses and squid.
These sharks are known to swim
in large schools off the coast of the galapagos islands. They have been found
to have routines, where they are very quiet in the day and active at night,
where they make many trips out into the open ocean. See Here for more details.
