There, in the dark ocean, a unique food web thrives not on photosynthesis but rather on chemical energy from the venting fluids. Among the creatures having a field day feasting at the Gorda Ridge vents is a diverse assortment of microbial eukaryotes, or protists, that graze on chemosynthetic bacteria and archaea.

Summer picnics and barbecues are only a few weeks away! As excited as you are to indulge this summer, Escherichia coli bacteria are eager to feast on the all-you-can-eat buffet they are about to experience in your gut.
