Sharks never lose teeth if one falls out another comes right back. Sharks can have up to 1 to 100 babies at a time depending on what shark it is. Some sharks are harmless. Sharks have been around for 40 million years. They were alive before the dinosaurs. Sharks are the top predators of the ocean's natural food chain. Every shark has a diffrent shaped tooth depending on its diet. A sharks jaws (top and bottom) both move unlike most other animals.

The oceans cover 71% of Earth's surface. The ocean consits of 6 levels ( The Sunlight, Twilight, Midnight, Abyss, Ocean Basin, and the Trenches).
Under water vents are sometimes called submarine volcanoes. These are estimated to a account for 80% of annual magma outputs. They can make islands when the head of a volcano's head sticks out. When the magma bubbles cool, they will burst. Since the water is realy cold, the magma cools realy fast. When they erupt they build up a layer and the more it erupts the more layers it builds up.
