Field Notes
We found a lot of green crabs under rocks and seaweed.Questions we ran into were there were no crabs in the first quadrant. You could see the green crabs, hear the current, and smell the salt water. I am surprised that we found a crab that was stuck in a rock and one that was 2 centimeters.

Very nice close-up images!

Hi Red Team 2,

Great observation! Your coordinates are off though. Please comment below with the coordinates of where you were sampling for these crabs and we can update your observation on the map.

sorry for the wrong coordinates I think these ones are right

These coordinates look closer but they still put you in the forest. Can you check in with your classmates and see if you have more accurate coordinates?

Thank you!
