Please identify yourself...
I was very surprised to discover the diversity of organisms living on the floating docks of Boston Harbor. This is some of what we found and tentatively identified:
1) Rock Weed - flat; broad; bladder-like air-filled sacs on the ends; Y-shaped forks.
2) Star tunicate - flat, star-like system; common in our area; whitish outline with clear or brown interior
3) Sea lettuce - bright green, ruffled, single broad sheet; common in brackish pools
4) Blue mussel - smooth bluish-black valved shell; violet inside; common in brackish water
5) Skeleton shrimp - pinkish-red; multiple segments; mantis-like claws; can stretch or collapse; tiny legs on final segments; abundant on fouling organisms
6) Orange sheath tunicate - number of orange stars compounded into a squishy mass; lives on docks
7) Northern rock barnacle - common in intertidal zone; plates are furrowed; white
8) Striped anemone - orange with numerous white tentacles
9) Spongomorpha - greenish-yellow; ropy and tangled
Much more that I was unable to identify:
