Caterpillars lack the proboscis and have separate chewing mouthparts. Some species have a reduced proboscis or maxillary palps and do not feed as adults. In some species, the pharynx is modified into a lengthy proboscis. In typical bloodsucking species, the female has an elongated proboscis. They feed by extending a large proboscis that bears four hollow jaws. The maxillary galeae are modified and form an elongated proboscis. Nemertea is a phylum of invertebrate animals also known as ribbon worms or proboscis worms. Proboscis monkeys are known to make various vocalizations. She also documented the extended proboscis of feeding insects. Instead, they collect pollen in a mass on the ventral side of their proboscis. Some species in the subfamily Pangoniinae have an exceptionally long proboscis (tubular mouthpart). Adult butterflies consume only liquids, ingested through the proboscis. The island is one of the habitats of the proboscis monkey. For example, it is seen in honeybees, in the proboscis extension reflex paradigm. The creature's mouth is located at the collar behind the proboscis.
