Named for their acrobatic leaping spins, spinner dolphins rest in sheltered bays during the day and hunt cooperative fish schools offshore at night. Small pods frequently patrol the cave entrance and adjacent reef areas throughout the year.

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.
