Juvenile reef fish in St. Croix reveal the hidden value of small coastal habitats

Along a rocky St. Croix shoreline, every single reef fish we observed was a juvenile. These shallow coastal pools, crevices, and rock shelters are easy to overlook, but they provide exactly the complex spaces young fish need. Larger coral reefs rightly command conservation attention, yet this observation gives us a compelling reason to investigate these smaller habitats more closely. Understanding which environments support juvenile fish is essential work. For deeper context, see our coverage of "Validated plastic debris now measurable in the deepest ocean trench."
