Field Notes
I am happy because we found an Asian Shore Crab and got pictures and information about it. We saw a green crab but could not catch it. I'm surprised that we caught the Asian shore crab but not the green crab.

We did not find the green crab. But we found an Asian-shore crab. How we know this is because this crab has 3 spines. The green crab has 5 spines

Agreed - what a great sketch!

Wow! That sketch is great. You clearly took your time and looked really closely. It also looks like you know crab anatomy. Thanks for sharing.
