rostrum

rostrum
1. A forward projection or extension of the snout (e.g. of a fish). The typical profile of an oceanic shark reveals a massive rostrum projecting well forward and above the low-slung mouth.

2. The snout-like extension to the head that forms the specialized piercing and sucking mouth-parts of the Hemiptera (true bugs). The stylets are sheathed by the labrum, which forms a jointed tube closed dorsally at the base by the labrum. In feeding, only the stylets enter the tissues of the host plant or prey.

3. In prawns, a spine-like extension of the cephalothorax.

4. (guard) In Belemnitida, a massive deposit of fibrous calcite.

5. In Brachiopoda, a beak-like process on the umbo.
