Info
The sea anemone Nematostella vectensis occurs in two distribution areas, one in the western Atlantic (east coast USA to the Gulf of Mexico) and the other an eastern Atlantic population around the British Isles.
The anemone lives in isolated or semi-isolated brackish pools in salt marshes and lagoons, in ditches and on mud flats in salt marshes and shallow estuaries at or above high water, typically in soft mud, silty sand and muddy gravel, but is also found on vegetation.
The entire anemone is translucent and colorless, except for a more or less distinct pattern of opaque white on the column and disk; the tentacles are usually banded white. This pattern varies in intensity and is occasionally absent altogether.
The 9-16 tentacles are very strongly adherent and arranged in two cycles, the outer ones being longer than the inner ones.
Synonym:
Nematostella pellucida Crowell, 1946
