Field Notes
I am happy because we found a lot of crabs and other species. I see the ocean, sand, people, and the glare of the sun on the ocean. I hear people talking, and boats, and I smell the ocean

Supporting Evidence
Photo of my evidence.
I think I found it because it has 5 spines and if you look on the id chart it says invasive species have 5 or fewer spines and was a greenish brown color.

Also, I think we found it because on the id chart it says green crabs have thin claws but shape at the end and that is what the crab we found has. another example is it has a pentagon shape and in the id chart, it says green crabs have a pentagon-like shape shell.
