Est-ce Androniscus roseus?
Sous une grosse pierre à moitié enterrée.
I highly recommend taking a look at this fascinating article on the remarkable rediscovery of Scyphacella arenicola by Dr. Pallieter De Smedt, featured on the Smithsonian's Website!

This is the second beach, out of four, with the species.
Undescribed genus; covered protracheoniscus type lungs places this in Agnaridae and not any of the other families. Exoantennal conglobation and coxal plates 2-4 demarcated from the pereionite proper are notable. Coxal plates 4-5 being modified for conglobation but not 3 or 2 seems very unique, I don't think this is yet known from any other crinochetan; All other conglobating groups I've checked seem to have coxal plates 2/3-4/5 modified.
Not 100% sure with initial ID, but some sort of roly-poly sandy coloured pill bug found on beach
The first isopod had an interesting pattern.
Many (100's) meandering on surface and re-entering numerous burrows into the sand.
