Why don t sharks just have bony jaws? There are several reasons why sharks don’t have bony jaws. One reason is that their cartilaginous skeleton makes them more flexible and agile in the water. Additionally, their jaws are filled with sharp, tooth-like structures called dermal denticles which help them to tear apart their prey. Finally, the size and placement of their gill slits also contribute to the efficiency of their swimming and feeding.

Why does shark don’t have bones? The main reason sharks don’t have bones is because they are composed of a substance called cartilage. Cartilage is much lighter and more flexible than bone, which makes it ideal for the fast-moving shark. Additionally, cartilage doesn’t break down as easily as bone, so it can better withstand the high pressures of the deep ocean.

How Come We Don’T Have Fossils Of Shark Skeletons?

There are a few reasons why we don’t have many fossilized shark skeletons. First, sharks have a lot of cartilage instead of bone, and cartilage doesn’t fossilize well. Second, sharks are constantly shedding their skin and teeth, so there aren’t many left behind to be fossilized. And finally, sharks live in the ocean where conditions aren’t ideal for fossilization.

How Do Sharks Have Teeth If They Don’T Have Bones?

Sharks have a unique type of tooth that is embedded in their skin. These teeth are made of a tough material called dentine, which is similar to human bone. The teeth are arranged in rows, with new teeth constantly moving forward to replace those that are lost.
