    "description": "The development of the octavolateralis system in fish ancestors created the\nphenomenon of sensory reafference associated with the fish's own locomotion.\nParticularly in fish species living and moving in groups, there is a potential to\nproduce complex pressure waves and other water movements interfering with the\noctavolateralis perception of critical environmental signals. The hypothesis\npresented is that the development of the octavolateralis system may have initiated,\nor been a factor in, the evolutionary development of synchronized group\nlocomotion, eventually leading to schooling behaviour. Theoretical models suggest\nthat schooling may be related to a reduction in masking of environmental signals,\nas well as to survival mechanisms, e.g. confusion of the lateral line and electrosensory\nsystems of predators by overlapping pressure waves and overlapping\nelectrical fields. The combined effects of reduced masking and predator confusion\nmay help explain why schooling became an evolutionary success. Including\npressure waves and other water movements in the model of join, stay or leave\ndecisions might shed some light on fish shoal assortment. A model encompassing\nthe complex effects of synchronized group locomotion on octavolateralis and\nelectro-sensory perception of both prey and predator fish might increase the\nunderstanding of schooling behaviour.",
