. Advances in marine biology: volume 17. Coral fisheries. ECOLOGY AND TAXONOMY OF Holimeda 305. Fig. 102b. The lagoon floor, here near the base of south Medreii pinnacle at approxi- mately — 40 ni, appears to be essentially barren of Halimedae, although the occasional plants were observed. Some of the erect structures in this photograph in the sand near the rock outcrop, height approximately 8 cm, are cylindracea. to — 5 m on the lagoon reefs of Jimini. Among green algae Tydemania is second only to Holimeda as a carbonate producer at Enewetak. Other noteworthy algal associates of Holimeda on vertical or near vertical faces of pinnacles, particularly below 20 m, were species of Cyanophyta, their reddish or purply filaments at times streaming from under overlapping plates of coral colonies. Masses of some of these filaments also grew out of the sand-rock substrate some distance from pinnacles. These Holimeda populations of the sides of pinnacles require more study because they may well be principal suppliers of carbonate to the reef floor. Gilmartin (1960) showed, and our own dives confirm, that the lagoon floors have very low densities of Halimedae growing on them, and yet there are the various bits of drill-core evidence that Holimeda segments are important constituents of the lagoonal sediments (Section IX). Holimeda macrophysa and some of the Opuntioids growing.
