Dense aggregations of golden Mastigias-type jellyfish occur in sheltered lakes, lagoons and calm bays around the Derawan archipelago (Maratua, Kakaban, Derawan islands).
These jellyfish form large, gently pulsing swarms that are ideal for snorkel and shallow dive viewing and are notable because many individuals have reduced or harmless stings.
