Types of sharks
There are more then 340 different species of sharks. Each shark looks alittle different from the other species that helps us tell them apart.
Types of sharks:
Great white sharks, whale sharks, hammerhead sharks, bonnet-head sharks, dogfish sharks, bull sharks, mako sharks, thresher sharks, tiger sharks, blue sharks, basking sharks, leopard sharks, nurse sharks, white tip reef sharks, megamouth sharks, lemon sharks, gray reef sharks, epaulet sharks, brownbanded bamboo sharks, porbeagle sharks, silky sharks, sand tiger sharks, oceanic whitetip sharks, great hammerhead sharks, goblin sharks, wobbegong sharks, zebra sharks, cookie cutter sharks, swell sharks, catsharks, longnose catsharks, varied catsharks, six-gilled sharks, bloodnose six-gilled sharks, and much, much more.
Sharks don't have bones, they have cartliage, (the stuff our ears and tips of our noses are made of).
Most sharks have to keep swimming in order to stay alive. If they stop swimming they sink to the bottom. They must keep swimming in order to pump the water and oxygen through their gills. The nurse, lemon, bull, and other sharks don't have to swim to breathe. They can pump water over their gills by opening and closing their mouths.
Sharks actually have several rows of teeth. When one tooth falls out, the tooth in the row behind it moves forward to take its place.
The biggest shark is the Whale shark. Some people mistake it for a whale, but it is a shark.
Sharks appeared on earth more than 100 million years BEFORE the Dinosaurs.
Bull sharks are the only type of sharks that can survive for a limited period of time in fresh water.
The liver, in some sharks, makes up more than 30% of their body weight.
There are four different feeding methods for sharks. 1. Ram Feeders who over swim their prey. 2. Suction Feeders who suck their prey in. 3. Bite and Gouge Feeders who bite into their prey then gouge (swallow) that piece whole. 4. Filter Feeders who take in water and take the tiny animals such as plankton from the water then release the water through their gills.
