ABSTRACT Our study describes the extraordinary capability of the endosymbiont-bearing bivalve Lucinoma aequizonata to tolerate environmental anoxia. The clam survives without oxygen for 262 days (50% mortality). The total quantity of glycogen in a specimen does not decrease significantly after long-term anoxia (10.5 too). Common glycogen-derived anaerobic products (opines, lactate, succinate, acetate, and propionate) are only produced in minor quantities. This indicates either seve...

The role of these symbionts, however, was not elucidated until a decade later when it was
