According to marine biologist and @TEDFellow Mike Gil, these fish copy each other all the time, constantly interpreting the tiniest movements, eating habits and cues of their fellow fish, and turning it into information about food sources or incoming predators. And they don't have to swim in schools or even be part of the same species to do this! “If even one fish sees a predator and flees, this can alert many others to danger,” explains Gil. “And a fish safely entering feeding grounds can show others that the coast is clear.” Watch Mike's full talk on the fascinating social lives of fish — and how their behaviors affect entire ecosystems — at the link in our bio.」11月9日 1時01分
