Geograpsus severnsi Paulay & Starmer, 2011

Severns' terrestrial crab



Taxonomy & Nomenclature



Conservation Status

Allied to G. grayi, the finding of sub-fossil remains of a terrestrial species of crab was a major find. Previously it was believed that no fully terrestrial decapod had colonized the islands. However, the species did not just colonize the islands, but at least several of them as sub-fossil remains have been found on Maui, Kauai, Molokai, Oahu, and Hawaii itself (Paulay & Starmer 2011, see Table 2).
