Finding a glistening piece of sea pork washed ashore may leave you thinking you’ve found just a piece of some other creature, resembling a piece of waterlogged pork or fatback (yummy!) This “blob” is actually a living creature, a very complex colony composed of thousands of tiny zooids wrapped in a cellulose housing, each in its own tiny sack like body. This celluloid housing is called a “ tunic” and protects the colony. You will find two external openings near each other that serve to circulate sea water through the sea pork in which nutrients are filtered out as food . Sea pork lives on the bottom and attaches itself to rocks, pilings, jetties or seaweed and is washed ashore by storms and high surf. Bottom feeders such as skates, and even some species of sharks, are known to eat sea pork. There are over 1,000 species of Ascidians worldwide, with numerous species of varying colors including red, yellow ,white , greenish-blue, and even purple appearing on our shores.
