Solution
The correct option is C Fishes
The lateral line is a system of sense organs which is found in aquatic vertebrates, mainly fish. It is used to detect movement and vibration in the surrounding water.
The sensory ability is achieved with the help of modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses.
Lateral lines play an important role in schooling behavior, predation, and orientation. For example, fish can use their lateral line system to follow the vortices produced by fleeing prey. They are usually visible as faint lines running lengthwise down each side.
