The Stalked Sea Squirt, Styela clava, is a solitary, hermaphroditic, ascidian tunicate that is found off Australia[2] and New Zealand,[3] both coasts of North America,[4] and Europe.[5]
These sea squirts are characterized by their brown or yellow, rough and wrinkled surface. They can grow to be about 6 in (15 cm) tall and can be found on lobster pots, pilings, and fishing nets. This species of sea squirts is native to Korea and Japan. It may have been carried to New England waters from Europe (where it arrived in the early 1950s) in ballast water or ship fouling.[6]
Styela clava is called Mideodeok(미더덕) in Korea and primarily consumed in there as food.
