Field Notes
We are happy because we get to go find crabs! Questions and problems we ran into were that we had to dig through lots of seaweed/rock to find crabs. We can hear and smell the ocean, the waves, the salty air, see seaweed, smell mud, and hear the scurrying of crabs. We are surprised of what we found and didn't find because we found an awful lot of green crabs and few native crabs.

Hi Yellow Team 2,

Great work on your observations! We noticed that you said you mentioned you were searching around Reversing Falls, but your 5 observations (this one, Asian shore crab, green crab, rock crab, and Jonah crab) are all on the next point over.

If you could comment below and with the correct coordinates, we can update your observations and get them back on track!

Thanks for all your hard work.

Looks like you are all set. Thank you, YellowTeam2.
