cont. of day 2

Once we arrived at the barking crab dock we formed into teams. okay just to let you know this is a late entry, but hey I'm trying, and what can I tell you? Doesn't matter what grade I get, it's that I learn and boy am I learning, thank you.
we measured the depth of the dock area which measured 18"6' give or take a few inches depending on the sludge on the bottom and we took the temperature which was 71 degrees 3 feet from the bottom (measured twice) and 74 degrees 3 feet from the top (measured twice).
at this point we cut out a portion of differently shaped shells and black moss, web like, what appeared to a clustered together by plant matter.
I've perused the Hitchhikers pamphlet and came across the tunicate and was able to identify some of the material we came across under the dock.
As a Group we made a particular discovery a translucent membrane bulb
found under the dock partially where it could get sun light,
which was squishy and dirt covered,
varying degrees of size 1 cm to 3 cm
several clustered together membrane on the outside was difficult to cut through, once cut a thick mucous oozed out, there was appeared to be a worm like encased within the mucous.

my other animal actually arthropod would be what appeared to be small slivers of sticks, like toothpicks or appendages (description from Audubon). In the "Audubon field guide" the closest description was between the long horn skeleton shrimp and smooth skeleton shrimp. where I got my descriptions of arthropod http://evolution.berkeley.edu/ bilateral symmetry, hard exoskeleton, jointed appendages or legs, many pairs of legs.

For plant life, we first saw a a green, mossy velvet like covering on the stone wall at the gangway to the boston Harbor cruises. To the right is a picture I drew of a green and dark green and black with bulbous ends when squeezed air and water (little) and slight pop sound. what I have found out doing a little research on http://www.britannica.com/ also looks a lot like Sargassum.

The velvet looking seaweed that was located next to a white hard shell cone looking (barnacles) a crustacean and arthropod, covering the wall in large formations.
