Ascidian

/əˈsɪdiən/noun

A sea squirt: a sac-shaped marine animal that filters food through two siphons.

The Greek roots

ἀσκίδιον
askídion
little wineskin

Literally: little wineskin

The story of the word

ἀσκός is a wineskin, the sewn goat hide that carried wine and water, and ἀσκίδιον is the diminutive. Sea squirts earned the name by shape, a leathery bag with two openings, cemented to a rock. Their larvae swim with a notochord and a nerve cord and then settle, glue themselves down and reabsorb the lot, which is how an animal named after a wine bag turns out to be a near relative of the vertebrates.
