Field Notes
it was fun looking for the Chinese mitten crab even though we didn't find it. though it was never in Maine, to begin with so we would never have found it. the Chinese mitten crab is easily identified because it has five ridges on the top.

Supporting Evidence
Photo of my evidence.
we did not find it because it inhabits freshwater which was not in the area we looked. Also, it has not been previously found in Maine before so we probably couldn't have found it even if we looked in fresh water.

we did not find the Chinese mitten crab because it is not in Maine yet so maybe in a year they will be in Maine but not now.

we did not find the Chinese mitten crab because in the area we looked there was no fresh water which is where the Chinese mitten crab inhabits so we did not find the Chinese mitten crab on this adventure
