[Butler_AB_and_Hodos_W, Comparative_vertebrate_neuroanatomy:_Evolution_and_Adaptation_(1996)_New_York:_Wiley-Liss_Inc., p.27][VHOG] XAO:0000459 The lateral line that is located below the eye. The mechanosensory lateral line system is widely distributed in aquatic anamniotes. It was apparently present in the earliest vertebrates, as it has been identified in agnathans, cartilaginous fishes, bony fishes, lungfishes, the crossopterygian Latimeria, and aquatic amphibians.[well established][VHOG] infraorbital line UBERON:0003094 ZFA:0000524 One of eight distinct lateral lines in the 4-day larva. A sensory system on the surface of the fish, consisting of small sensory patches (neuromasts) distributed in discrete lines over the body surface. The lateral line system is stimulated by local water displacements and vibrations, and detects propulsion of the fish through the water, as well as facilitating shoaling, prey capture, and predator and obstacle avoidance.
