Field Notes
When my group got to Reid State Park we helped unload the bus and got all of our materials. We worked in a quadrat and put it over places that had seaweed and rocks. We were trying to find an Asian shore crab, but unfortunately we did not. Reid State Park smelled like the ocean and at times you could smell something fishy. The sounds we heard there were birds, people, waves, and wind. The weather that day was sunny, but cold. The highest temperature was 60 degreesF. I was surprised because I did not expect some of the crabs to be so feisty. I even got pinched a few times!
Supporting Evidence

The Asian shore crab has three spines. The crab we found was a green crab because it has 5 spines. This shows that this is definitely not a Asian shore crab because it has a pentagon.
