Field Notes
During our field trip our group was looking for the invasive Asian Shore Crab. At the beginning of our field work we found some shells of the Green crab. After ten minutes we found a live Green Crab we detected this because from our observations we made. We also found several other marine organisms other than crabs like sea stars, sea urchins, periwinkles, bladder wrack, and mussels.

Supporting Evidence
Photo of my evidence.
It is not Asian because it did not have spotted bands on its legs, it turned out to be a green crab because it had no bands and had the shell design (pentagon-shaped shell) of a green crab.
Photo of my evidence.
It is not Asian because it has 5 spines like the green crab, unlike the Asian shore crab which has 3 spines.

It is not Asian because it doesn't have a trapezoid shell, it has a pentagon-shaped shell like a green crab.
