Divergent Chemosymbiosis-Related Characters in Thyasira cf. gouldi (Bivalvia: Thyasiridae)
Within the marine bivalve family Thyasiridae, some species have bacterial chemosymbionts associated with gill epithelial cells while other species are asymbiotic. Although the abundance of symbionts in a particular thyasirid species may vary, the structure of their gills (i.e., their frontal-abfront...
