Field Notes
We went to Reid State Park and Todd’s Landing on Tuesday, October the 24th to pick up the traps we previously set and collect new data as well. We left our school at eight-thirty to get on a bus to go to Todd’s Landing. Our teacher went out with waders and collected the traps. We found a fish and some lobsters. After collecting our traps we got back on the bus and went to Reid State Park. There were traps there as well, and while other groups went to collect data first, our group and few others went to take the traps out. We found even more lobster and more crab. Then we went back to the other side of the bridge and set up a quadrant. We took several pictures and found very few green crabs in the area. We found zero Asian shores and found about two green crabs on our own. It was obvious they were green crabs because they all had five spines and were small. After taking notes and finishing up our research, we went back to school and continued our work.
Supporting Evidence
In this photo we found a green crab. We knew this because the crab had 5 spikes instead of 3 spikes like the Asian shore crab.
Then in this photo of a green crab, we knew it was a male because its telson was skinny unlike a females telson which is wider.
