Coral reefs are living colonies made up of thousands of small individual corals (called polyps) on the ocean floor. They’re slow growing and are a key marine ecosystem – supporting a huge range of animals like fish, molluscs and sea urchins. In recent years, they’ve taken a battering from overfishing, unsustainable tourism, pollution, and global heating.
But it’s not all doom and gloom. Recently, there’s been a little reason for optimism when it comes to these crucial living structures.
Chinks of light
Here are three positive reef stories that have recently come to light:
- Marine researchers discovered one of the biggest coral reefs that’s ever been found off the coast of Tahiti – and it appears to be in pristine condition. At between 35-70 meters, it’s slightly deeper than most coral reefs, so it’s hoped there could be more undiscovered gems out there.
- Dolphin poo could help save coral reefs, according to a recent study by the Zoological Society London. Spinner dolphins feces contains special nutrients that can help boost the resilience and productivity of coral reefs. In light of these findings, scientists are calling for their protection.
- The Australian Institute of Marine Science’s Annual Summary Report on Coral Reef Condition 2021/22 shows increases of 7-9% in some parts of the northern and central Great Barrier Reef.
Let’s hope the coming months and years bring more good news when it comes to the health of coral reefs, so vital to the wellbeing of our marine world.
