Injured Squid Have Higher Survival Chances

A painful injury can up a squid’s chance of survival against predators, National Geographic reports. Researchers who wanted to see how a minor wound affects the longfin inshore squid’s behavior snipped off a tip of its arm. When the animals encountered a predator, 45% of squid that knew they were hurt survived, whereas less than 25% of those that had been anesthetized and could not feel the pain lived. The finding, published online this week in Current Biology, suggests pain can make animals act more self-protectively.
