It could be worse: Find out what would happen to you if you were a shark sibling in this chilling tale of embryonic cannibalism. To begin with, sharks are a the most vicious and terrifying creatures to roam the big blue. They, like other Chondrichthyes, have skeletons made of cartilage instead of bone. Cartilage is tough, rubbery material which is less rigid than bone. Cartilaginous fish also include skates and rays. This lady here is full on insights as far as sharks go and their capabilities. She has done the research and she is eager to tell you all about it. If you happen to be interested or even upgrade your knowledge on these species go ahead and take a look at this video as it is bound to broaden you horizons. There are more than 350 different kinds of sharks, such as the great white and whale sharks. <a href="https://rumble.com/v4gtmp-teen-gets-wish-granted-will-search-for-fossils.html" target="_blank">Fossils</a> show that sharks have been around for 420 million years, since the early Silurian. The great white shark is one of the biggest sharks. Most sharks are predators, meaning they hunt and eat fish, marine mammals, and other sea creatures. However, the largest shark eats krill, like whales. This is the whale shark, the largest fish in the world. It is widely believed that <a href="https://rumble.com/v38hin-great-white-sharks-circle-divers-at-guadalupe-island.html" target="_blank">sharks</a> are "silent-killers" but in a recent study it has been proven that sharks emit a low/soft but evident growl from their throats resonating through their scales. Some common kinds of shark include the hammerhead shark, the great white shark, the tiger shark, and the mako shark. Most sharks are cold-blooded but some, like the great white shark and the 'mako' shark are partially warm-blooded.
