Field Notes
What I heard that day was the wind brushing against my skin, and I heard the loud yelling of kids. Also I saw the fine compact sand on the beach and I also saw large gropes of rocks piled together. All I could smell was the strong sent of salt water.

Supporting Evidence
Photo of my evidence.
We think that we did not find this species of crab, because in this photo the crab we found had a distinct spotted back. We compared the photo we were Supplied with and we saw the Asian Shore Crab witch had a spotted back Instead of the Chines Mitten Crab.
Photo of my evidence.
In this photo we think that we did not find the Chines Mitten Crab, because the one that we found only had three spines. We figured out that three spikes is one less then the Chines Mitten Crab has four spines. In conclusion we think we only found the Asian Shore Crab.

Lastly the crab that we found had claws that did not look like mittens witch the chines mitten crab had. Instead the crab that we found did not have the mittens like the chines mitten crab.
