Please help to identify this crab

Caribbean.
Could not get a better shot because it was under a ledge, under sea urchin.
Thank you in advance.

Interesting, it appears that both answers are correct at least according to Wikipedia. Thank you to both of you!

The problem is common names.
Two quite separate and distinct species are called Sally Lightfoot: Percnon gibbesi and Grapsus grapsus; the latter is found on the Pacific coast and is also called the red rock crab, the former is also called the nimble spray. You were in the Caribbean; you saw a P. gibbesi. To avoid confusion you'd best call it a nimble spray. And if you'd seen it in the Galapagos, you'd best call it a red rock. They don't even look alike. The leg markings are your ID key for your picture.

Grapsus grapsus

Percnon gibbesi

Yes, thank you.
Nimble spray is what how I saved it in my photo library. Although sally lightfoot is a very cool name.
