Rostrum (from Latin rostrum, meaning beak) is a term used in anatomy for a number of phylogenetically unrelated structures in different groups of animals.
Crustacean: the rostrum of the shrimp Macrobrachium rosenbergii is serrated along both edges.
Insect: assassin bug piercing its prey with its rostrum
Cephalopod: the two-part beak of a giant squid
Proboscis of hawk-moth (Agrius convolvuli)
In mammals, the rostrum is that part of the cranium located in front of the zygomatic arches, where it holds the teeth, palate, and nasal cavity.
The beak or snout of a vertebrate may also be referred to as the rostrum.
Sailfish, like all billfish, have a rostrum (bill) which is an extension of their upper jawbone
The paddlefish has a rostrum packed with electroreceptors
Sawfish have an electro-sensitive rostrum (saw) which is also used to slash at prey
