Question

How does the oil from the liver provide limited buoyancy in the absence of a swim bladder

Answer 1

Unlike fish, which have a gas-filled swim bladder that keeps them afloat in the water, sharks rely upon a huge, oily liver to provide some buoyancy. The oil in the liver is lighter than water and gives the shark some buoyancy, but it is still heavier than water and will sink if it dos not actively swim.

Answer 2

The oil which is found in liver of the shark is called squalene, which is lighter than the water.

Since shark's body is heavier than the water he can sink into the water but the buoyancy provided by the oil help him to swim actively and prevent sinking.

fish have a gas- filled swim bladder that keeps them afloat in the water and prevent them by sinking into water.
