Why? Because fish are actually 'social' creatures. In the sea they swim in shoals, so it makes perfect sense that they would need companions.
你问为啥?因为鱼类实际是“社会性”生物。在海里它们成群地游动,因此它们需要同伴合情合理。
"It turns out the amazing synchronised swimming that fish in shoals exhibit is actually caused by each fish using very simple rules to respond to its neighbours," says Herbert-Read.
