... and retraction can be modeled as a fixed pulley that lacks the speed amplification occurring in gnathostome jaws. Hagfish gape cycle times are approximately 1 s,and are longer than those of gnathostomes, suggesting that a functional advantage of jaws is the speed that allows gnathostomes to exploit elusive prey...
