Best places to dive with Kakaban golden jellyfish

Mastigias cf. papua

The most numerous of four stingless jellyfish species isolated in Kakaban's marine lake, alongside Aurelia, Tripedalia and Cassiopea. Long isolation has left its stinging cells too weak to penetrate human skin. This is a separate population from Palau's endemic Mastigias papua etpisoni, and Indonesian sources apply both Mastigias papua and Mastigias cf. albipunctatus to it, so the name recorded here is provisional.

Thousands of jellyfish were reported in the lake in 2026, redistributed away from the old jetty after the 2023-24 disappearance. The uncertainty here is access, not the animals: the lake reopened in February 2025 with swimming banned and operating rules still being drafted, so you may be limited to viewing from the boardwalk.
