Getting a fish to bite is one of the most important aspects of angling, but how exactly does a fish eat? Fish jaws are much different from our own; the simple act of taking a bite is the result of a heavily coordinated movement that involves a number of fused bones called an operculum. This bony flap is what allows fish to take a gulp of water and flush it back out through their gills in one fluid motion.

Smarter Every Day and Dr. Jamie Seymour of James Cook University take a closer look at the mechanics of a fish bite in the following video.
