Derawan islands consist of 31 islands including Pulau Derawan, Pulau Kakaban, Pulau Sangalaki, Pulau Maratua, Pulau Panjang dan Pulau Samama. It lies on Sulawesi sea at Berau Regency, East Kalimantan Province. Two inhabitant islands are Pulau Derawan and Pulau Maratua. The islands is home for dolphins, green sea turtles, hawksbill sea turtles, manta rays, whale shark, whitetip shark and hammerhead shark and many pelagic fish.
Long time ago, tectonic activity forces some area of atoll to surfaces above the sea level to became an island and surrounded some sea water in the middle of the island to form a lagoon. Some animals trapped inside lagoon evolved to adapt the new environment including 4 species of jellyfish. The lack of the predator evolved the jellyfish to lose it’s sting ability and become stingless and non-poisoned to human. And that their name came from: stingless jellyfish. The island is called Pulau Kakaban and the brackish water lagoon is called Danau Kakaban.
Recently, Stingless jellyfish also found in several places in Indonesia such as Pulau Maratua (Derawan islands, East Kalimantan), Raja Ampat (West Papua), Togean islands (Central Sulawesi) and Rote island (East Nusa Tenggara).
