Evolutionary relationships of the bivalve family Thyasiridae (Mollusca: Bivalvia), monophyly and superfamily status. Webb5 mars 2024 · Chemosymbiotic thyasirids are mixotrophs that appear to rely on particulate food to a greater extent when symbiont abundance is low , or at times when environmental sulfide concentrations are low . All thyasirid symbionts identified to date are gammaproteobacteria [ 23 , 25 , 26 ].

The burrows are formed by the foot of each bivalve, which can extend up to 30 times the length of the shell, and may be the most extreme case of animal structure elongation documented to date. q22 tws stereo headset manual
