Abstract
Endozoic microalgae were found in most snails collected from coral reefs and beachrock communities in the Red Sea. Algae were identified microscopically as well as by chromatography and spectrophotometry of pigment extracts. The algae were located in the hepatopancreas and the gonads, organs which are permanently concealed within the shell. According to pigment analysis, most of the endozoic algae belong the Chromophyta, perhaps dinoflagellates, except for a few chlorophytes.
