Question

Lateral line system found in fish has been lost in amphibians due to

• A. Development of limbs
• B. Change over to herbivorous feeding
• C. Occurrence of metamorphosis in frog
• D. Evolution of terrestrial habit

Answer 1

The correct option is D Evolution of terrestrial habit

The lateral line is a system of sense organs found in aquatic vertebrates, mainly fish, used to detect movement and vibration in the surrounding water. The regression of the neuromasts and their innervation at metamorphosis shed light as to how the lateral line system was lost with the evolutionary origin of terrestrial amniotes.
Therefore, the correct answer is option D.
