In a heart-wrenching display of self-preservation, a determined crayfish defied destiny and pulled off its own claw to escape a bowl of boiling water.

A video shared on the Chinese social media site Weibo shows a crayfish, also known as a crawdad, crawfish, mudbug, or freshwater lobster, at the edge of a pot of boiling water. Shockingly, the creature uses its right claw to pull off its left, leaving the wayward arm to become part of a meal, along with the other crayfish in the bowl, as you can see in the above video.
