More information: F. Javier González-Barrios et al, Emergent patterns of reef fish diversity correlate with coral assemblage shifts along the Great Barrier Reef, Nature Communications (2025).

Their findings show Great Barrier Reef fish communities differ substantially from those of the 1990s, and the pace of change has increased.

Covering nearly 133,000 square miles (345,000 square kilometers), the Great Barrier Reef is the world’s largest coral reef, home to more than 1,500 species of fish and 411 species of hard corals.
