Field Notes
I am happy because we are outside and found many crabs. The Questions and problems I ran into are they were aggressive and kept trying to crawl out of the box we had the crabs in. I see seaweed, I hear the water and the wind, and I smell saltwater.

Great pictures Green Team 3! About how many crabs did you all find during your search? Were any other species found within your class group?

Thank You! We found around 20 crabs in our class group. We did not find any species other than Green Crab.
