Which of these male crabs have dimorphic claws?

I loved watching the little crabs scatter & create their abodes with the little sand spheres that they would dig out, as a kid I would watch them with great amusement on the shore line with the waves ebbing to & fro, making sand castles & collecting shells. Oh what simple days lol I loved digging for pippies with the feet too though I could never seem to find any I saw plenty of people doing it who did & others fishing .. oh a lovely life lived near the beach, near the sea, simple what blissful days.

* Seshati *, How lovely. I hope you’re an author as I was right there on that beach, toes in the sand, dodging waves and watching crabs scuttle about.

* Seshati *, Such a beautiful comment...who would give it a thumbs down???

crabs are creepy,the way they scuttle &look with their eyes on stalks!

I guessed right! Dimorphic?
