When an earthworm is underground, which type of receptors will relay information on directional movement?
A) Lateral line organs
B) Otoliths
C) Cristae
D) Stereocilia
E) Statocysts

Question

Quizplus · Accepted Answer

Statocysts are sensory organs found in some invertebrates, including earthworms, that help them sense gravity and orientation, thus aiding in directional movement underground. They contain small granules or statoliths that move in response to gravity, providing the animal with information about its position relative to the ground. This makes them crucial for an earthworm's navigation while burrowing.
