The picture to my right I believe to be baby sea anemones. I say this because they are very squishy to the touch and when you do touch them, they retrieve into a smaller ball (look at the anemone on the left for that example) which larger anemones also do. I also believed they were anemones because the one on the right shows a bunch of white squigglies in the center. None of which come out, but that may be because they have yet to fully develop? Who knows. Either way, I looked them up and found they match a description of "Striped Anemones" especially considering their orange stripes on the black body.
In the picture to my right are two sea anemones and some Bushy Bryozoan. The two sea anemones while similar are quite different in color. The top anemone is a more pale apricot, while the bottom anemone has more of an organish-tint to it... interesting yes? Well I thought so, so I tried to see if they were any different in the guide book and came up with the following conclusion. They are the same. Haha, the speces just comes in different shades. They are both Frilled Anemones.
These creatures were easily seen by the hundreds along the dock. They were literally crawling and squiggling over and on everything. While when there are that many of them they can be hard to distinguish between, but I believe we either found more than one type of arthropod, or there is a major distinction between the female and male sex of these creatures... it's one of the two assuming they aren't asexual.
This picture on my left also suggests further that these specimen are not the same. Notice how the creatures you see in this picture are more transparent and have more defined claws than the darker red creature depicted above. For these reasons, I think this specimen on the left could be the Smooth Skeleton Shrimp. It is fairly long although not 2'' like the guide suggest, however it was the closest picture match I could find. However, as we discussed in class the pictures aren't the most important information to go off of, so though it could be the Smooth Skeleton Shrimp, I think it is more probable to be the Linear Skeleton Shrimp, since it's location includes Boston Harbor.
