Field Notes
It was a wet and rainy day, the clouds were covering the sky. We had just arrived at the beach where we would look for the specimen we have decided to search for, it was about 9:00 am. The beach is called Kettle Cove Beach. It is almost in the very center of a local neighborhood. It was very wet and damp, and the rocks were slippery because it rained earlier that day. It was as if there was a fire, the air was so gray and foggy. It was cool but it was also very humid outside, because it was mid fall. The beach was rocky on the edges and sandy in the middle section of the beach. The fishing boats were like rubber ducks floating in the water as a faint silhouette. We could see the abnormal amounts of tidal pools and crabs. All throughout the day, you could faintly hear the waves crashing on the shore. There was a fresh smell of salt water which was infecting the fresh air. We could all hear the rumble of groups talking and yelling towards each other. The specimen our group was searching for is the Colopomenia Peregrina, also known as the Sea Potato. We ran into the problem of locating the specimen under all the seaweed and rocks in and out of the water. Our group was anticipating that we would have a very hard time finding the Sea Potato. We found the Sea Potato very rapidly under the seaweed, which really surprised us because it had not been located many times in Cape Elizabeth before. It was located in the crevice of a tidal pool , and detached from seaweed.
Supporting Evidence

We think we found the Sea Potato. The Sea Potato has green-brown to yellow-brown color. This basically makes it an olive color. As shown in the photo above the organism we found has an olive color. This clearly sets it apart from the Sea Cauliflower which has a muddy brown color. This is evidence on why we think we found the Sea Potato.

We think we found the Sea Potato. The Sea Potato has epiphytic growth which means it grows off organisms like seaweed. As shown in the photo above the organism we found looks as if it was attached to something like seaweed or something similar to seaweed. This clearly sets it apart from the Sea Cauliflower which had lithophytical, growth which means it can grow off things including rocks and similar things to rocks. This is evidence on why we think we found the Sea Potato.
Photo of my evidence.
We think we found the Sea Potato. The Sea Potato is very thin-walled, and hollow, and its middle section is usually collapsed in on itself. The Sea Potato has such thin walls you can almost see what is behind it. As shown in the photo above, the organism we found also has collapsed in on itself. This clearly sets it apart from the Sea Cauliflower, because the Sea Cauliflower has thicker walls, and looks like a brain. This is evidence on why we think we found the Sea Potato.

Wow! Very nice work Mullet mafia. You did a wonderful job explaining your reasoning and taking clear photos that connect well to your written evidence. I am nominating this post for "best all around observation". Keep us the good work.
