Great work identifying this crab!

Wow! 109 crabs and all invasive. Is that what you predicted you might find or were you surprised by these results?

This was our first time doing this investigation, so we were unsure what to expect. We had hoped to find at least a few and were very surprised to find so many and all invasive!
