Grey reef sharks at Shark Paradise patrol the reef edge in groups of three to twelve individuals, making coordinated sweeps along the reef crest at dawn and dusk when prey fish are transitioning between diurnal and nocturnal resting areas. Their social patrolling behaviour may allow coordinated prey herding that increases individual hunting success rates beyond what solitary hunting would achieve. The population density at this site is exceptional by Indian Ocean standards and reflects Rodrigues Island's lack of reef fishing pressure.

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.
