Blacktip Reef Shark

Carcharhinus melanopterus

Sighting evidence at Bulan Reef Turtle Garden, Donsol

Blacktip reef sharks cruise the outer edge of the reef in loose groups, their distinctive black-tipped fins cutting the surface in the shallows at dawn and dusk. These sharks are inquisitive but non-threatening, approaching divers within a few meters before veering away, and their presence is a reliable indicator of the reef's good ecological health. Juveniles shelter in the extremely shallow sandy lagoon areas, making them observable even by snorkelers.

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.
