The gill morphology of the date mussel Lithophaga lithophaga (Bivalvia: Mytilidae)

Morphological Effects of Pollution on Gill of Common Clam, Tapes decussatus Linnaeus, 1758 (Bivalvia: Veneridae)

“…Dufour and Beninger (2001) stated that the abfrontal surface is a vestigial mucociliary epithelium and that the different distributions of cilia and mucocytes seen on the abfrontal surfaces of bivalve gills result from selective forces that vary in nature and degree. This study demonstrates a distribution of cilia similar to other bivalves (David and Fontanetti, 2005;Aksit and Mutaf, 2014). Gregory et al (1999) studied the morphology of Perna perna gill filaments exposed to different concentrations of mercury and found some alterations that included loss of abfrontal cilia and an increase in the number of cilia on the lateral surface.…”

“…al. 1996), Perna perna (Gregory and George, 2000), Mytella falcata (David and Fontanetti, 2005) and Lithophaga lithophaga (Aksit and Mutaf, 2014). The lateral cilia are responsible for pumping water into the bivalve shell and latero-frontal cilia are clearly important for particle retention by filter feeding bivalves, as discussed previously (Moore, 1971;Jones et.…”

“…The blocks with a scabrous surface present in the slits next to the marginal groove and between the tissue junctions of the lamellae are assumed to grate captured food particles that are large relative to the size of the aperture through which they must enter into smaller pieces to be molded with mucus and consumed by the bivalve as stated by Aksit and Mutaf (2014).…”

alidation of reference genes for quantitative expression analysis by qPCR in various tissues of date mussel (Lithophagalithophaga)

“…Being a rock-boring bivalve, it is among the first to inhabit bare limestone rocks and, with burrowed tunnels and holes, form the basis for settlement by endolithic, benthic, and other sessile species (Gonzalez et al, 2000). Previous studies on the date mussel have focused on morphology (Morton and Scott, 1980;Owada, 2007;Aksit and Falakali Mutaf, 2014), reproduction (Valli et al, 1986;Šimunović et al, 1990;Kefi et al, 2014), colonization patterns (Grubelić et al, 2004;Devescovi and Ivesa, 2008;Devescovi, 2009), and burrowing (Jaccarini et al, 1968;Kleemann, 1973;Bolognani et al, 1976;Bolognani Fantin and Bolognani, 1979;Kleemann, 1996). Only a few studies have investigated the genetics of the species (Giribet and Wheeler, 2002;Martinez-Lage et al, 2005;Vizoso et al, 2011;Nishihara et al, 2016), and none have evaluated the expression stability of reference genes.…”

Mytilus galloprovincialis as a smart micro-pump

“…Frontal surface currents take the particles separated by latero-frontal cilia to the nutrient groove (Riisgård et al, 1996). While several research groups investigated the morphology and evolution of mussel gills in order to understand the flow mechanics through the interfilament canals and frontal surface currents (Brennen and Winet, 1977; Jørgensen et al, 1984; Gueron and Liron, 1992; Cannuel et al, 2009; Aksit and Mutaf, 2014), these studies lacked real-time flow measurements. This present study is unique in that it visualized and quantified the velocity field at the coronal plane during suction feeding through a particle image velocimetry (PIV) technique.…”
