Multigene Molecular Systematics Confirm Species Status of Morphologically Convergent Pagurus Hermit Crabs
Introduction: In spite of contemporary morphological taxonomy appraisals, apparent high morphological similarity raises uncertainty about the species status of certain Pagurus hermit crabs. This is exemplified between two European species, Pagurus excavatus (Herbst, 1791) and Pagurus alatus (Fabrici...
