• A. Shallow Sea fishes
• B. Deep Sea fishes
• C. Deep River fishes
• D. Shallow River fishes

Answer 1

Answer: (B)

Deep Sea fishes

A higher proportion of unsaturated fatty acids is present in deep sea fishes.

Deep sea fishes will need the unsaturated fatty acid chains in order to lower the critical temperature for the transition from a liquid crystal (fluid) to a gel phase. As the temperature in the deep sea is very low.

So, the correct option is 'Deep Sea fishes'.
