Extreme Mangrove Corals Found on the Great Barrier Reef

The first documented discovery of "extreme corals" in mangrove lagoons around Australia's Great Barrier Reef is yielding important information about how corals deal with environmental stress, scientists say. Thirty-four species of coral were found to be regularly exposed to extremely low pH, low oxygen and highly variable temperature conditions making two mangrove lagoons on the Woody Isles and Howick Island potential "hot-spots" of coral resilience.
