they don't come from the same family like bull sharks they are not part of the hammer-head shark
They just know......
well the main difference is that a horses spine is made of bone while a sharks is made of cartilage.
sharks have large crap we have crap 75% smaller
Well,there has to be a difference between them or people would not have named them differently.
Sharks are cold-blooded, and are a species of fish; Dolphins are warm-blooded, and are mammals.
Some sharks have bones like us however some sharks have bones that are made out of cartilage.
One difference is that fish are bony. Sharks have a skeleton made of cartilage (like in your nose or kneecap). Sharks have five to seven gill slits, while fish only have one. Fish have swim bladders for bouyancy, sharks do not.
sharks swim, have flippers. Dogs have fur, don't really swim and have no flippers.
Cats are mammals and sharks is a fish. One lives in land the other in water.
It is believed that sharks attack humans because humans vaguely resemble seals, and some species of sharks do eat seals. Sharks are not intelligent enough to tell the difference between a human being and a seal.
Sharks became extinct during the epic battle of the sea to decide which of the two mammals TRUELY ruled the seas between the sharks and the dolphins. The sharks were no match for the dolphin's almighty power which caused the sharks to all die off as the dolphin leader conquered all the sharks till they became extinct.
difference between that's it and that's all
