Good job - this is indeed a green crab. Next time, you can also count the spines on each side of the eye. 5 spines means it is a green crab.

Looks like your coordinates are a bit off. I like to use this online tool to figure out the right spot. It's handy because it gives you your latitude and longitude in the right units (decimal degrees).

Looks like a green crab to me too!
