lateral line canal

The lateral line system is a unique sensory organ found in aquatic vertebrates like fish and amphibians. It's composed of specialized mechanoreceptors called neuromasts, arranged in a network along the head and body. These organs detect subtle water movements and pressure changes, allowing animals to sense nearby prey, predators, or even stationary objects through water displacement.12

In many fish, these neuromasts are housed within mucus-filled canals beneath the skin, known as lateral line canals. These canals have small openings to the outside, allowing water displacement to stimulate the neuromasts within. This system is crucial for navigation, detecting movement, and understanding the surrounding aquatic environment.231
