Black-tip reef sharks are shallower and more active than white-tips and are frequently seen cruising the reef crest at 5 m to 10 m at Shark Point. Their presence at a site accessible to beginner divers makes the Gilis unusual in the region: most comparable sites with reliable shark density require advanced certification.

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.
