Publisher Description: There are more than 500 known species of sharks living in our oceans today. Sharks are the apex predator at or near the top of their marine food chains. They regulate the populations of species below them. In research has shown that massive depletion of sharks has cascading effects throughout the ocean's ecosystems. Sharks belong to a family of fish that have skeletons made of cartilage and a tissue more flexible and lighter than bone. Sharks breathe through a series of five to seven gill slits located on either side of their bodies. All the sharks have multiple rows of teeth, and while they lose teeth on a continuous basis, new teeth continue to grow in and replace it those they lose. |
