Are small fish actually safer from predators in a dense school rather than spread out?

225 views

It seems to me that if they spread out from each other, so a predator could only eat one in every bite, any single fish is safer because it’s less likely to be that single one, whereas if they’re huddled together and the predator can gobble ten at a time, the likelihood for any single fish being eaten in a bite is 10x higher.

I understand if the optics of a school are designed to look big and maybe scare off predators, but it’s always been phrased to me as if the “game theory” for a single fish makes it safer to pack in with others.

If you’re in a street fight against 2 dudes, do you think you’re more likely to get hit if there is 1 of you, or 10 of you? Who gets hit is all about statistical probability.
