Endosymbiosis in the lucinid clams lucinoma aequizonata lucinoma annulata and lucina floridana a reexamination of the functional morphology of the gills as bacteria bearing organs



Endosymbiosis in the lucinid clams lucinoma aequizonata lucinoma annulata and lucina floridana a reexamination of the functional morphology of the gills as bacteria bearing organs



Marine Biology (Berlin) 96(1): 79-86



A three-dimensional representation of the structure of the endosymbiont-containing gills of Lucinoma aequizonata, L. annulata and Lucina floridana was constructed using light and electron microscopy of fresh and plastic-embedded thin-section samples. The gills of these lucinids are identical in overall structure, each being composed of three structurally and functionally distinct regions here called the ctenidial filament zone (CFZ), the transition zone (TZ), and the bacteriocyte zone (BZ). Rather than a simple medial extension of the filament tissue, the bacteriocyte tissue is organized as an array of cylindrical tubes, the walls of which are composed primarily of bacteriocyte cells covered by a thin microvillar epithelium. The physical relationship between the symbionts, the host tissues and the external environment are examined, and structural constraints on the potential functions of bacteria in this host-symbiont system are discussed.
