This Applied and Environmental scholarly article reports experimental evidence of parallel speciation patterns in Squid-Vibrio symbioses. The article presents the derived molecular phylogenies for an array of sepiolid squids and their symbiont strains, an analysis of these phylogenies that revealed parallel cladogenesis between these partners, and an experimental demonstration that a hierarchy exists in the ability of bacterial symbionts from different species of squids to colonize the Hawaiian squid, Euprymna scolopes.
