Genus Ocypode, these are called Ghost crabs of their ability to disappear from sight almost instantly. Their once Claw is generally larger than the other. I had been to Ullal beach, Mangalore where I spotted these small crabs. Finally, it's a break from posting birds in the previous many posts.
They take in oxygen from the water that washes over their gills, hence they need to get frequently washed by the surf.It was a thrilling experience tracking these crabs and getting larger than life images of them.
