lateral lines
Lateral lines are specialized sensory organs found in aquatic animals, particularly in fish and some amphibians. They consist of a series of small, fluid-filled canals located along the sides of the body. These canals are lined with sensory cells that detect changes in water pressure and movement, allowing the animal to sense nearby objects and other creatures.
This ability helps fish navigate their environment, avoid predators, and locate prey. The lateral line system is crucial for survival in dark or murky waters where visibility is limited. It is an excellent example of how evolution has equipped animals like fish with unique adaptations for their habitats.
