Proboscis

Male elephant seals can be easily identified by their large proboscis, which resembles an elephant’s trunk (and is the source of their name).

Males begin developing this enlarged nose, or proboscis, at sexual maturity (about three to five years of age) and it is fully developed by seven to nine years.

Don Caldwell, editor-in-chief of the site Know Your Meme, namechecks Brr Brr Patapim, “a proboscis monkey that is also a tree”, as one who made it to YouTube.

Unlike the proboscides of Lower brachyceran lineages, which are continuous with the head capsule and tend to dangle (Matsuda 1965), the proboscides of most cyclorrhaphan species are suspended by a membranous region and divided into three functional parts: the basiproboscis (rostrum), medioproboscis (haustellum), and distiproboscis (labellum), each of which is defined by internal muscles but also shares muscles with the other regions (Graham-Smith 1930; Lall and Davies 1971).
