Vase tunicate

The vase tunicate has a thin, smooth, weak sac. It is also translucent. Nevertheless, the sac is very tough. These animals are eaten in countries surrounding the Mediterranean Sea. They cut open the sac and slurp the animal up. Be aware if you plan on eating one that it makes some people feel very miserable! They discover that they are allergic.

  • Distribution and habitat

    Vase tunicates are common in the delta region, North Sea, Wadden Sea, in harbors on pontoons, buoys, stones, boats, wrecks, legs of drilling rigs and other such hard surfaces.
