Many symbionts live in association with different species. It can be expected that these
distinct hosts might have a different effect on key life-history traits of the associated …

We studied how host-associations and geography shape the genetic structure of sister
species of marine snails Coralliophila radula (A. Adams, 1853) and C. violacea (Kiener …

The great diversity of marine life has been shaped by the interplay between abiotic and
biotic factors. Among different biotic interactions, symbiosis is an important yet less studied …

Many members of the bivalve superfamily Galeommatoidea have symbiotic associations
with other marine benthic invertebrates. Among them, Koreamya arcuata (A. Adams, 1856) …

Bivalves commonly associate with other organisms, however, examples of true parasitic
associations are described only for members of the marine superfamily Galeommatoidea …

The bivalve Tellimya fujitaniana (Galeommatoidea, Heterodonta) was described based on a
fossil shell. Until now, the biology of living animals has not been reported. In this study, we …

The development of host races, genetically distinct populations of the same species with
different hosts, is considered to be the initial stage of ecological speciation. Ecological and …

Sagamiscintilla thalassemicola (Bivalvia: Galeommatoidea: Galeommatidae) is a rare
ectocommensal bivalve that lives on the proboscis of echiuran worms, Anelassorhynchus …

Compared to host shifts, the importance of within-host cladogenesis in the diversification of
symbionts remains less well understood in marine systems. Yoyo clams (Galeommatidae …

Evolutionary transitions to parasitism are rare. In this study, we documented a potential step
toward parasitism in the commensal clam Kurtiella pedroana (Bivalvia: Galeommatoidea) …
