Reef Ecosystems
Coral reefs cover less than 1% of the ocean floor yet support more than 25% of all marine species. We explore the biology, the ecology, and the extraordinary complexity of these systems - from symbiotic relationships at the cellular level to the large-scale dynamics of reef recovery after bleaching events.
Explore Reef ScienceScience & Conservation
Reef science moves fast. Coral restoration, assisted evolution, acoustic monitoring, deep reef refugia - we track the research that matters and explain what it means for the future of reef ecosystems worldwide.
Conservation StoriesWhy CoralCoe Exists
Coral reefs are among the most studied and most threatened ecosystems on Earth. The science is rich, the stakes are high, and most of what reaches the public is either buried in academic journals or diluted into something unrecognisable.
CoralCoe is an independent editorial resource built to sit between those two extremes. We cover reef biology, marine ecology, conservation science, and reef travel - with the rigour of informed writing and the accessibility of a publication made for people who are genuinely curious, not just casually interested.
Our content draws on peer-reviewed research, field experience, and direct engagement with reef systems across the Indo-Pacific, the Red Sea, the Caribbean, and beyond.
The Voice Behind the Site
CoralCoe is led by Daniel Mercer, a reef writer and marine ecology enthusiast based in Queensland, Australia. With a background from James Cook University - home to one of the world's leading concentrations of coral reef scientists - Daniel has spent over a decade diving, researching, and writing about reef systems across the Indo-Pacific and beyond.
The site reflects a simple conviction: that reef science is too important and too fascinating to remain locked behind paywalls and academic language.

One Ocean, Countless Reefs
From the shallow coral gardens of the Great Barrier Reef to the deep mesophotic reefs of the Coral Sea, from the biodiversity hotspot of the Coral Triangle to the resilient reefs of the Red Sea - coral reef ecosystems exist across 109 countries and territories, each one distinct, each one connected to the same global ocean system.
CoralCoe covers all of it. Reef biology, dive guides, conservation updates, marine life profiles, and destination resources - built into a single independent reference point for anyone who takes the reef seriously.
