Caja de Muertos hosts recovering stands of elkhorn coral in the shallows, a species that was nearly wiped out across the Caribbean by disease and bleaching events. Their return here is considered one of Puerto Rico's most significant reef conservation success stories, with juveniles now visible alongside adult colonies.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
