“…Indeed, because genera were initially poorly defined in Vesicomyidae, recent work has attempted to clarify the taxonomy of the family (see Krylova and Sahling 2010 for review). However the taxonomic and phylogenetic study of this group is still in progress, and the incongruence between clades and named genera is fairly evident from our, as well as from other authors' phylogenies (Peek et al 1997;Goffredi et al 2003;Kojima et al 2004;Decker et al 2012). …”

“…Genome sequencing of symbionts has emphasized several traits typical of maternallytransmitted bacteria, including genome size reduction coupled with the loss of certain genes (Kim et al 1995;Harada et al 2009;Kuwahara et al 2008;Stewart et al 2008). The systematics and evolution of Pliocardiinae hosts have also been studied but their taxonomy is still under debate as genera are typically found non-monophyletic in phylogenetic reconstructions (Kojima et al 1995;Baco et al 1999;Osborn 2001;Goffredi et al 2003;Kojima et al 2004Kojima et al , 2006Decker et al 2012). Yet, apart from large-sized Pliocardiinae vesicomyids, there are in this subfamily smaller-sized species which have been overlooked, and for which very little data is available, both for hosts and associated symbionts.…”

The smaller vesicomyid bivalves in the genus Isorropodon (Bivalvia, Vesicomyidae, Pliocardiinae) also harbour chemoautotrophic symbionts

Species of Isorropodon are vesicomyid bivalves for which little information is available regarding host phylogeny and bacterial symbioses. In this study we investigated the symbioses in three Isorropodon species from three cold seep areas: Isorropodon bigoti (Gulf of Guinea), Isorropodon megadesmus (Gulf of Cadiz) and Isorropodon perplexum (Eastern Mediterranean). Analysis of bacterial 16S ribosomal RNA gene sequences demonstrated that each vesicomyid species harbours a single symbiont phylotype, that symbionts from the three species cluster together, and that they are closely related to other known vesicomyid symbionts. These results are confirmed by other marker genes (encoding 23S rRNA and APS reductase) and by fluorescence in situ hybridization. Due to their extended depth range and transoceanic distribution Isorropodon species are interesting examples to further study evolutionary processes in bivalve hosts and their associated symbionts.

“…Molecular phylogenetic studies indicate two separate groups among species with the general shape of Pliocardia: one includes the species Vesicomya stearnsii, Calyptogena ponderosa, C. cordata, and 'Pliocardia' krylovata, the other includes Vesicomya kuroshimana, V. crenulomarginata, and specimens called "cf. venusta" (Kojima et al, 2004;Martin and Goffredi, 2011;Audzijonyte et al, 2012). Several additional extant species for which no molecular data are available are also included in this genus (Krylova and Sahling, 2010), as well as several fossil taxa Kiel, 2007, 2012).…”

Abstract.-Eleven species of chemosymbiotic bivalves are reported from middle to late Miocene methane seep deposits ('Calcari a Lucina') in the Italian Apennines, including seven new species and one new genus. The new species are Bathymodiolus (s.l.) moroniae and B. (s.l.) miomediterraneus among the Bathymodiolinae and Archivesica aharoni, A. apenninica, A. strigarum, and 'Pliocardia' italica among the Vesicomyidae; specimens from the middle Miocene of Deruta are reported as Archivesica aff. aharoni. Samiolus iohannesbaptistae new genus new species is introduced for an unusual mytilid with a commarginally ribbed surface, which might be the first non-bathymodiolin mytilid obligate to the seep environment. The two large lucinid species from which these deposits derived their informal name 'Calcari a Lucina' are identified as Meganodontia hoernea (Des Moulins, 1868) and Lucinoma perusina (Sacco, 1901). With Chanellaxinus sp., we report the first thyasirid from a Neogene deep-water seep deposit in Italy and the first fossil occurrence of this genus.

“…These differences in reproductive periodicity are puzzling, considering the very close phylogenetic relationship between C. kilmeri and the C. soyoae/okutanii complex. In fact, C. kilmeri may be conspecific with C. soyoae based on molecular analyses presented by Kojima et al (2004). Reproductive periodicity appears variable in chemosynthetic mussels.…”

Our knowledge of the reproductive biology and ecology of most deep-sea animals is very limited due to the logistic difficulties of deep-sea investigations. In this study, spawning by males and females of the vesicomyid bivalve Calyptogena soyoae and C. okutanii complex were observed in situ over 1 yr using the long-term deep-sea observatory located at cold seeps in Sagami Bay, Japan. Egg-and sperm-spawning events by clam aggregations occurred roughly 90 and 213 times m -2 for 1 yr, respectively, and the local population of the C. soyoae and C. okutanii complex yielded 5.8 × 10 8 eggs m -2 yr -1 into the water column over the seep location studied. Males displayed a 'sprinkle siphon' behavior, waving their siphons left and right to sprinkle sperm into the water. Female spawning by egg release into the water column was always preceded by male spawning and decreasing near-bottom current speeds. Two hypotheses are proposed for cues to stimulate egg release by C. soyoae/okutanii females. First, a 'double trigger' hypothesis requires the presence of sperm in the water column and decreasing current speed before eggs are released. Second, a 'single trigger' hypothesis requires that egg release is induced when compounds in or released with sperm exceed a threshold concentration. These results demonstrate the utility of long-term observatories for studies of deep-sea reproductive biology, particularly for species characterized by rare, episodic spawning events.
