Captive tilapia study shows cold-blooded animals using behaviorally-induced fever to battle infection

A team of life scientists at East China Normal University has found that at least one type of cold-blooded animal uses behaviorally-induced fever to battle infections. In their paper published in Proceedings of the National Academy of Sciences, the group describes how they put Nile tilapia, a type of fish, in tanks with a heat gradient, infected them with a bacterium and then watched how they behaved—and what they learned by doing so.
