This hard coral is common in shallow water exposed to surge, in the highest wave energy environments. [8] M. flabellata is less common and more restricted to shallow reef habitat, colonies of the species were found between 1 and 4 m depth. [9] The species is a broadcasting, simultaneous hermaphrodites that release egg-sperm bundles. [9]
The results of Job and Ceccarelli's 2010 survey [20] were published as the Tuvalu Marine Life Scientific Report in 2012. [21] showed that the mean hard coral cover of Funafuti, Nanumea and Nukulaelae were 15%, 11% and 6%, respectively. with Funafuti having a higher mean coral cover, which was attributed to better water flow through the large reef passes (ava) and greater habitat diversity due ...
