The feeding mechanism shown here - jaw protrusion - allows a fish to envelope prey items by extending its reach, in one example (the sling-jawed wrasse), by up to 65% of the normal resting length of the head. This animation illustrates the preparatory, expansion, and recovery phases in the opening, protrusion, and closing (respectively) of the jaw in a stylized bony fish's head.
