Mona Island hosts one of the densest Caribbean reef shark aggregations in Puerto Rican waters, with individuals cruising the wall drop-offs at depths of 15–35 m. Their presence reflects the reserve's strict no-take status, which has allowed predator populations to recover significantly over the past two decades.

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.
