Gio's Great Page of Shark's

 

 

 

Sharks have been on this earth nearly 400 million years.

 They have the most powerful jaws on earth. They never run out of teeth the have many rows of them. They may go through 20,000 teeth in their life! They also very in sizes from the size of a pointer finger to 40 feet long !

 

  

 

 

                                                                              Many people think that sharks are dangerous and killers, but truthfully most shark attacks are do to mistaken identity. They are very very fascinating creatures. There are over 380 species of sharks on earth ! About 115 of shark species live in North America. One specie can be found in every ocean. Sharks come in differant sizes like these photos above, they can be short,long,fat,and wide. The one thing sharks have in common is that they are all fish. Shark's may have 5 to 7 gill slits. Shark's get most of their air by taking water in through the mouth,passing it to the gills and out the slits. They must also swim constantly or they will die. There might be other sharks such as the the nurse sharks that do not have to be in motion to live,they spend most of their time on the ocean floor.

 

              Like most fish, sharks have fins. They have five differant kinds. The pectorl,dorsal,pelvic,anal, and caudal. Some sharks may swim in bursts of up to 30 mph ! But they usually swim 1-5 mph. Some sharks swim many miles in a day such as the soupfin shark swims 35 miles a day! They body shape of a shark may tell up how they live.
