"lateral line"의 정의 및 의미

What is "lateral line"?

The lateral line is a specialized sensory system present in fish and certain aquatic animals. It consists of a series of small sensory organs called neuromasts, which are arranged in a line along the sides of the body. These neuromasts detect changes in water pressure and movement, allowing the animals to sense vibrations, water currents, and the presence of nearby objects or prey. The lateral line system plays a crucial role in the navigation, feeding, and social interactions of these animals in their aquatic habitats.
