Marine Endolithic Cyanobacteria - 2
An ooid sand grain, less than 0.5 mm across, contains an entire
assemblage of endolithic cyanobacteria and other microorganisms that penetrate
carbonate substrates. Microborings were embedded and cast in araldite,
cured, cut open, and the surrounding carbonate removed by dilute
hydrochloric acid. Shallow subtidal waters (ca 2m depth) off the coast
of Saudi Arabia at Dhahran (cf. Al-Thukair & Golubic 1991a, b;
Al-Thukair et al. 1994).
