Recently, researchers announced that a super-large coral found on the Great Barrier Reef—coral is a structure composed of small marine animals and calcium carbonate
.

This huge coral is the widest and sixth tallest coral on the Great Barrier Reef

This coral was discovered by snorkelers off the coast of Orpheus Island, which is part of the Palm Islands in Queensland, Australia
.

The Manbarra people who have been guarding the Palm Islands historically named this coral Muga dhambi (Great Coral)

Adam Smith of the Australian Coral Reef Ecological Alliance and his colleagues studied the large coral and found that it has a hemispherical shape with a height of 5.
3 meters and a width of 10.
4 meters, which is 2.
4 meters wider than the second widest coral in the Great Barrier Reef
.

Based on the coral growth rate and annual sea surface temperature calculations, the researchers estimate that the appearance of large corals occurred between 421 and 438 years ago, earlier than the earliest Europeans discovered and settled in Australia

In addition, after reviewing environmental events in the past 450 years, the researchers found that large corals may have experienced as many as 80 major hurricanes and have been exposed to invasive species, coral bleaching events, low tides, and human activities for hundreds of years
.

Researchers found that the large corals are in good health, with a 70% coverage of live corals, and the rest are green perforated sponges, turf seaweeds and green algae

Researchers recommend that this rare and extremely resilient large coral be closely monitored and believe that it may need to be restored to minimize future climate change, deterioration of water quality, overfishing and coastal development.
