Sea Urchin, Green – Maine

Green Sea Urchins, members of the phylum Echinodermata (“spiny skin”), are found in the Pacific and Atlantic oceans.  In the Atlantic they are found from the Canadian Arctic down to New Jersey.

They are hand-caught by divers, so bycatch is minimal with no damage to the habitat. However, along the coast of Maine, Green Sea Urchins are at a critically low abundance.

Sea Urchins graze on seaweed and are eaten by many animals, and therefore are an important link in the marine ecosystem.
