Scientists have discovered the largest coral ever recorded in the southwest Pacific Ocean, which could be over 300 years old.

Unlike traditional coral reefs, this mega coral is a collection of many tiny connected organisms, forming a single entity. It surpasses the size of a blue whale, measuring 34 meters wide, 32 meters long, and 5.5 meters high.

The coral was found by videographer Manu San Felix during a National Geographic expedition to study climate change's impact on remote Pacific regions. Felix, diving in the Solomon Islands, initially thought he had found a shipwreck but soon realized he had discovered something extraordinary. 'It was like seeing a cathedral underwater,' Felix said, reflecting on the emotional impact of encountering such a historic organism.

The discovery was made during a dive in deeper waters, which may have shielded the coral from the warmer surface temperatures affecting other reefs. Scientists have praised the coral's health despite the global threats to coral species from climate change. The specimen, Pavona clavus, provides a habitat for various marine life, including shrimp, crabs, and fish.

The discovery comes at a crucial time, coinciding with the COP29 climate talks in Baku, Azerbaijan. Trevor Manemahaga, climate minister for the Solomon Islands, expressed his pride in the discovery, emphasizing the importance of protecting such vital marine ecosystems for the country's economy. The coral's longevity offers scientists a valuable opportunity to study past oceanic conditions, adding hope amidst global coral decline.

A recent report revealed that 44% of corals in warm waters face extinction, highlighting the urgency of protecting these delicate ecosystems against further climate impacts.
