Today was our first day getting out to the islands and in doing so we got a look at completely different bio-diverse environment and had all day to explore it. We got right into the tide pools and started to explore. Today I did a lot of things I have not done before - well touched a lot of things I never thought I would. There was so much life in the tide pools and because the environment was so different from the docks at the barking crab the life inside was too. The environment at the barking crab was brackish water and in an urban area - and the tide pools on the island were salt water and more open to the environment with less pollution and people around them.
The first things we saw were the crabs - they were moving quickly and large enough to see from a good distance so they were the first thing to catch my eye. There were 3 types of crab that I believe I saw today: asian shore crabs , rock crabs, hermit crabs (I think it was the acadian hermit crab to be exact). We also saw a lot of other plant and animal life: periwinkles , sea squirts - which I found so interesting since they actually squirt water when lifted out of the water, mussels, clams, sea urchin shells, lobster, and tunicate - grey and orange in different areas, this had a hard shell and based on what I learned today contains a jelly substance on the inside, and I found a sea urchin shell but there was nothing alive in it anymore - the shell was very intricate, green and bumpy & it was very delicate and thin.
The periwinkles and crabs were the most common and the sea urchin was the least common since I only saw shells.
Then we were also asked the question of why some shells have a perfect circular hole in them. In the past I have seen these at the beach and the first time I saw them I thought that maybe there where shells people were making necklaces with that they threw back - obviously not the case - so this challenge was very interesting to me. The wholes are created from predators that are hunting the animals inside the shells. In Massachusetts this is most likely whelks.
See you all on Wednesday for some more exploration!
