The upper mandible is strong, but light,the hooked tip serving as a guard against the escape of fish,while the lower mandible is simply a light frame which sup-ports the pouch. As the bill is opened in grasping the preythe sides of this frame are bowed outwardly by the actionof a set of muscles for that purpose, the tip being contracted,and the mandible and pouch becoming a very serviceable dipnet.
