Day 8.230: What did we catch?

Back on Day 8.128, I set a little teaser, did you spot what we saw in the tide pool (in Acadia National Park - at the end of the Wonder Land trail) in this picture?

Maybe a closer look will help?

Do see it (about a third of the way up and in from the bottom right corner)?

The large crab was hiding very well - tucking its claws in, but was also managing to cling to the rocks, but tenacious Exile #4 eventually managed to dislodge it:

After a short examination, we let it go again - it posed for a photo:

and then scuttled away and found a new hiding place under a different ledge in the pool. I think it's a Jonah crab.
