WebSymbiosis Over the course of evolutionary history nematodes and sulfur-oxidizing chemoautotrophic bacteria have formed symbiotic relationships in marine sediments on at least two independent occasions. Mouthless worms of the genus Astomonema have endosymbionts which live intracellularly or extracellularly in the gut rudiment of their host. WebThis chapter describes such symbioses, speciﬁcally those between marine invertebrate and protist hosts and chemosynthetic bacterial symbionts. These bacteria, which cluster primarily within the Gammaproteobacteria (Fig. 1), are chemo- autotrophs or methanotrophs.
