I never have in all my years of exploring beaches and tidal pools. Does anyone know what it is?

From Wikipedia-
Libinia emarginata is roughly triangular in outline and very heavily calcified, with a carapace about 4 in (100 mm) long and a leg span of 12 inches (300 mm).[4] The whole crab is khaki, and the carapace is covered in spines andtubercles,[5] and, as with other decorator crabs, often clothes itself in debris and small invertebrates.[4]
