Abstract

Endolithic algae living inside skeletons of living corals are exposed to very low light intensities. Assays carried out on the coral Porites compressa revealed drastic diurnal fluctuations in pH and O₂ levels within the skeleton, dominated mainly by coral photosynthesis by day and respiration at night. Enzymatic activity of carbonic anhydrase and catalase, as well as photosynthetic adaptations to low light level and low metabolic activity rates, enable the algae to grow in this unique habitat.
