Answer 1

The correct option is A

Fish

A lateral line is a system of sense organs that fish use to detect movement and vibration in the surrounding water. They use it to detect depth and water pressure, prey, predators, sense current movement and orientation in the current, as well as to avoid collisions. All fish have some form of a lateral line, some having a more developed one then others. Lateral lines are usually visible as faint lines running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. Most amphibian larvae and some adult amphibians also have a lateral organ.
