![]() When the animal dies in a watery environment and is buried in mud and silt, the animal skeleton becomes fossilised. Do you know what fossilize means? It is the process of an animal becoming preserved in a hard form. Their flexible skeleton allows sharks to open their mouth further for a strong bite and become powerful predators.ĭo you know that sharks can fossilize?!! Yes even though sharks don’t have bones, they still can fossilize. Some parts are made from softer cartilage such as their snout, which can act like a bumper that can absorb heavy blows without suffering and help them to absorb oxygen easily. Some areas are needed more protection, so they are made from calcified cartilages “calcium salts” such as sharks’ heads to protect their brains. Their bodies are made from different strengths of cartilage and some areas are stronger than others. The cartilage that makes up the spinal column of the shark is calcified enough to protect the spinal. Their spinal column is made from cartilages, which protect the spinal cord the same way that the bones do. Sharks have backbones but it is not made from bones, it is made from cartilage. How are sharks classed as vertebrates and they don’t have bones? Sharks are considered vertebrates, which means that they have a backbone. The cartilaginous skeleton also protects its organs and gives their bodies shape and structure. Although sharks have a cartilaginous skeleton, it does the same job that a skeleton made from bone does. Cartilages are the clear gristly stuff that our ears and nose tip are made of. ![]() They are from the class Chondrichthyes which means cartilage fish and from the subclass “Elasmobranchii” which includes all sharks, rays, and sawfish.ĭo you know what are cartilages? They are tissues that are more flexible and softer than bone, they also are much lighter than real bone. Certainly, we thought that sharks have tough bones but in fact, they have a skeleton that is made from cartilage rather than bone. Sharks are one of the most powerful creatures in the ocean and have an incredible bite force. Most living organisms have a skeleton that is made from bone that gives their body shape and gives them strength. They are the strongest predators in the world that can adapt well to the areas that they live in. They’re often known as “living fossils” as they have roamed the oceans for more than 400 million years, meaning they were even around before the dinosaurs. Some live near the surface, some live in the deep water, some live on the ocean floor, and others stay near shore or on coral reefs, while some live in open oceans. They can be found in the Atlantic, Pacific, Indian, Arctic and Southern oceans. Sharks are a special kind of fish that live in every ocean in the world, mostly in warm waters. Nowadays, there are more than 500 species of shark in the world and come in all different shapes and sizes. However, there are more interesting facts about sharks than you may know. Have you ever seen a shark? Sharks have a fearsome reputation.
