1.1 Entomology (In many insects) an elongated sucking mouthpart that is typically tubular and flexible.
- Its proboscis, which looks like a nose but is actually the longest mouthpart of any known fly, protrudes as much as four inches from its head - five times the length of its bee-size body.
- On the underside of the head is the paired proboscis, which is used to suck nectar from flowers.
- When the hawk moth proboscises were long compared to the length of the flower tube, the hawk moths did not efficiently pick up pollen, and the flowers did not reproduce well.
1.2 Zoology (In some worms) an extensible tubular sucking organ.
- Echiurans have an extensible proboscis and a set of small hooks at the posterior end; hence the Latin name of the phylum, ‘spine-tails.’

- They are carnivorous, scavenging among carrion or preying on other molluscs, using their extensible proboscis, tipped with a radula, to reach into and extract nourishment from their victims.
Early 17th century: via Latin from Greek proboskis 'means of obtaining food', from pro 'before' + boskein '(cause to) feed'.
