Sharks: Pictures of Sharks - 50 Most Secret With Sharks Facts

     Sharks have adapted to living in a wide range of aquatic habitats at various temperatures. While some species inhabit shallow and coastal regions, others live in the open ocean, on the ocean floor and in deep waters. Like the bull shark, some species are even known to swim in fresh, salt, and brackish waters.

     Most sharks are especially active in the evening and night when they hunt. Some sharks swim over great distances to feed and breed. This can take sharks over entire ocean basins. Even some shark species are solitary, others shows social behaviour at various levels. The Hammerhead sharks, for instance, school in the time of mating season around seamounts and islands.

     Some shark species, like the great white shark, from below surprise their prey, usually seals and sea lions. Species that dwell on ocean floor have developed the ability to bottom-feed and others attack schooling fish in a feeding frenzy, while the large sharks like the whale and basking sharks filter feed by swimming through the ocean with their mouths open wide, do filtering large quantities of plankton and krill.

     Sharks mature slowly, and reach reproductive age anywhere from 12-15 years. This, combined with fact that many species only give birth to one or two pups at a time, means that the sharks have great difficulty recovering after their populations have declined.

Soon after birth, sharks pups swim away to fend for themselves. Sharks are born with fully-fledged sets of teeth and are able to feed and live on their own.
