Abstract
Prokaryotes lacking a cell wall, formerly known as mycoplasmas were recently designated as the new class, Mollicutes. The association of unidentified “mycoplasma-like organisms” with aquatic animals has been suggested previously on the basis of visual observations alone. We report the pure-culture identification of a true mollicute, anAcholeplasma, that consistently associates with the larvae and adults of the marine bryozoanWatersipora arcuata. This represents the first confirmed nondisease association between a mollicute and an aquatic invertebrate.
