What is the correct sequence of events required for fish to detect the physical presence of other fish within the school?
A) Water currents cause the cilia within the gelatinous membrane to bend, which causes a nerve impulse to go to the brain.
B) Sound waves cause the cilia within the gelatinous membrane to bend, which causes a nerve impulse to go to the brain.
C) A chemical signal will cause the cilia within the gelatinous membrane to bend, which causes a nerve impulse to go to the brain.
D) Water currents cause a nerve impulse to go directly to the brain.
E) A chemical signal will cause a nerve impulse to go directly to the brain.

Question

Quizplus · Accepted Answer

Fish detect the physical presence of other fish primarily through changes in water currents. These currents cause the cilia within the gelatinous membrane of their lateral line system to bend, which then generates a nerve impulse that is sent to the brain. This system allows fish to sense movements and vibrations in the water, helping them navigate, avoid predators, and stay within a school.
