Threats to Evolution of Sharks? Sharks have existed for over 400 million years. Sharks predate the dinosaursAs sharks are cartellagenouss, fossil evidenceof early sharks is from fossilized teeth and a few skin impressions. Cladodonts, primitive sharks, had double-pointed teeth, were up to 6 feet (2 m) long, ate fish and crustaceans, and lived about 360 million years ago (mya). Finning - shark fin soup...Sharks mature slowly, and reach reproductive age anywhere from 12 to 15 years. This, combined with the fact that many species only give birth to one or two pups at a time, means that sharks have great difficulty recovering after their populations have declined CountershadingFusiform ShapeAmpullae of LorenziniLateral LineGillsDermal DenticlesHeat Exchangers There are now over 400 species of sharks!

While some species inhabit shallow, coastal regions, others live in deep waters, on the ocean floor and in the open ocean. Some species, like the bull shark, are even known to swim in salt, fresh and brackish waters.
