The Amazon Reef (also referred to as the Amazonian Reef) is an extensive coral and sponge reef system, located off the coast of French Guiana and northern Brazil. It is one of the largest reef systems in the world known to exist, with scientists estimating its length to be over 600 miles (970 km) long, and covering over 3,600 square miles ...
The channel runs east to west from 1.8 to 30 m (6 to 98 ft) deep with a fine white sand bottom, numerous mounds and patches of branching corals under the deep blue water. The north lagoon is an enclosed triangular coral reef platform partly exposed during low tide. It is relatively shallow with depths of about 2–10 m (7–33 ft).
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]
