The crabs blend well in to the rocks and the front one looks like it's trailing, uh, slime? The sharpness of the colour is a little too strong for my eyes for some reason. Not sure what you've done there, if anything.
That certainly is some good natural camouflaging, Denise...I can see how easy it would be to miss seing them too. I like how you composed this...and the way the larger one's form is set against the green water in contrast...neat how the eyes stand out on the top of the body. Nice photo, Denise...and an intersting subject to capture . MFC
