Examples of proboscis in the following topics:
-
- Nemertea, or ribbon worms, are distinguished by their proboscis, used for capturing prey and enclosed in a cavity called a rhynchocoel.
- A unique characteristic of this phylum is the presence of a proboscis enclosed in a rhynchocoel.
- The proboscis serves to capture food and may be ornamented with barbs in some species.
- The proboscis may be extended or retracted by the retractor muscle attached to the wall of the rhynchocoel.
- This image shows the internal structures of a basic nemertean, including the proboscis and the rhynchocoel: 1: Proboscis 2: Rhynchocoel 3: Dorsal commissure of brain 4: Rhynchodeum 5: Proboscis pore 6: Ventral commissure of brain 7: Mouth 8: Foregut 9: Stomach

- In the sandfly's midgut, the parasites differentiate into promastigotes, which multiply, differentiate into metacyclic promastigotes, and migrate to the proboscis.
