Hawksbills use the bay's sponge-rich boulders as a feeding ground, grazing on encrusting sponges that most species cannot digest. Resident individuals are regularly seen resting under ledges at 8 to 14 m, making close-range observation reliable. Nesting season peaks June through October on Chachacual's beach, bringing additional females into adjacent waters.

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.
