What Do Sharks Have To Help Them Float?
For flotation, sharks rely on their liver which is filled with oil and fats.
Their liver has two parts which are filled with oil and fats, substances that are lighter than water helping in this way to float.
Liver is as much as 25% of the shark weight and although it helps for buoyancy, sharks must swim continuously or otherwise they will sink.
