Ciliopagurus caparti belongs to the group of hermit crabs that is sometimes called left- handed because the left claw is larger than the right, as opposed to the situation in other hermit crabs. C. caparti was originally described as a new genus Trizopagurus. The original description in Bulletin, Institut Royal des Sciences Naturelles de Belgique, 28(39): 1–8 is available for download from ATOL:Decapoda. We hope that our just submitted samples will yield DNA-barcodes of the species in the BOLD database.
