This Pachycheles rudis (Thickclaw Porcelain Crab) with a 1" carapace is right-handed.
This Pachycheles rudis (Thickclaw Porcelain Crab) with a 1" carapace is left-handed and was under a rock w/6 other crabs. I've never seen so many as today, when there were dozens under rocks.
This crab is dead but I don't usually come across these so took a photo, anyway.
This crab was only an inch or two wide.
Breeding colors, lovely!
Not confident on identification.

Porcelain crabs are decapod crustaceans in the widespread family Porcellanidae, which superficially resemble true crabs. They are typically less than 15 mm (0.6 in) wide, and have flattened bodies as an adaptation for living in rock crevices. They are delicate, readily losing limbs when attacked, and use their large claws for maintaining territories.
