Question

What happens when a piece of shark liver is placed in water? What is an advantage of such property?

Answer 1

Ans: Shark liver consists of a low-density compound which is naturally organic and is called Squalene. Squalene is mostly present in the cartilaginous fish such as shark because these organisms lack a swim bladder. So this Squalene reduces the density of the body with fat and oils present in the shark liver. As specific gravity plays a pivotal role in the fluid which relates to viscosity and the density property. Shark liver is generally lighter than the water with the specific gravity of 0.855 which indicates a floating property of the body and opposed the condition of drowning into the water. Hence If that liver of shark is placed in water it will float by regulating the bouncy property in the water.

The advantage of such property of Squalene in the liver of shark is to regulate the bounciness into the water and helps it to swim properly into the water irrespective of its weight.
