Rostrum (from Latin rostrum, meaning beak) is a term used in anatomy for several kinds of hard, beak-like structures projecting out from the head or mouth of an animal. Despite some visual similarity, many of these are phylogenetically unrelated structures in widely varying species.
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for pecking , grasping , and holding (in probing for food, eating , manipulating and carrying objects, killing prey , or fighting), preening , courtship , and feeding young.
The rostrum is very prominent and contains 11 to 14 dorsal teeth and 8 to 11 ventral teeth. The first pair of walking legs ( pereiopods ) is elongated and very thin, ending in delicate claws ( chelipeds ), which are used as feeding appendages.
