bosci-, bosc-

(Greek > Latin: to feed, to graze)

Apparently bosci is always used in combination with pro-, "before", as in proboscis.

An order of terrestrial mammals (Ferungulata) comprising the elephants and their extinct relatives; typically with a large body size and showing development of a trunk from the nose and upper lip; teeth reduced, upper jaw often with tusks.

It includes elephants and mammoths (Elephantidae), mastodons (Mammutidae) and the Deinotherioidea, Moeritherioidea and Gomphotheridae.

1. A long flexible snout or trunk, as of an elephant.
2. The slender, tubular feeding and sucking organ of certain invertebrates; such as, insects, worms, and mollusks.
3. A human nose, especially a prominent one.
proboscidian, proboscidean
Of or belonging to the Proboscidea, an order of mammals typified by a trunk or proboscis and including the elephant.
1. Any tubular extension of the head or mouth parts; especially, one used for feeding.

An elephant's trunk, perhaps the best known example, is a long muscular elongation of the upper lip and nose. It is used for transferring food to the mouth, and for sucking up water, which is then squirted into the mouth.

The end of the trunk has a pair of nostrils and also finger-like lobes, which can pick up small objects.

2. The slender tubular feeding and sucking structure of some insects (moths or butterflies) and worms.
3. In general, a proboscis is an elongated appendage of a living organism.

The most common usage is to refer to the tubular feeding and sucking organ of certain invertebrates like insects, worms, and mollusks.

4. The term is used for primate organs as well: an elongated human nose, especially a prominent one, is sometimes called a proboscis (as a joke) and the Proboscis Monkey is named for its enormous nose.
