Field Notes
It was a beautiful sunny day at Kettle Cove Beach. We did not find it. which is good. We found lots of green crabs big and small and sea potatoes of all sizes. we also found dead mans fingers but, no sign of the mitten crab anywhere. My partner and I thought we had found a baby but it was just a green crab.
Supporting Evidence
Photo of my evidence.
This is a green crab. we know this because we used our ID card and saw it had 5 and under spikes, so it was invasive and not native and we compared the spikes of the two crabs and it was the green crab spikes instead of the chinese mitten crab.

(these are all the same crab just different evidence for each square) The claws where different they didn't have the stuff on them. The green crab has no rock looking stuff on the end of there claws.
Photo of my evidence.
The number of spines is different. the green crab has five spines and the Chinese mitten crab has four. The crab we caught or the one up above has five spines, not four.
