Fish also migrated to same nest each year, but unlike migratory bird such as white storks or swallows, the fish does not migrate over long distances. Instead, it disappears for the month and travelling offshore to feed. Male shannies (Lipophrys pholis) were already known to return to their nest if they were artificially removed during their breeding season from October to April.
But, Paulo Esteves Jorge at University of Lisbon in Portugal stated that it is not yet clear how shannies find their way back, and they may use scent, visual landmarks or other cues. "many species od intertidal rock-pool fish have excellent homing capabilities backed up by fantastic spatial learning" says Culum Brown at Macquarie university in Sydney, Australia. The researchers also still wonder why these animals only stay in the breeding area for a month during the breeding season.
