Sharks detect motion in the water or waves by their:

A) lateral lines.
B) electroreceptors.
C) keen olfaction.
D) sight.
E) dorsal fin.

Lateral Lines

A sensory system found in aquatic vertebrates, used to detect movement and vibration in the surrounding water.

Electroreceptors

Specialized sensory receptors that certain aquatic animals possess, allowing them to detect electrical fields in their environment.

Keen Olfaction

The highly developed sense of smell, often found in animals, enabling them to detect and distinguish odors more acutely.
