Derawan islands is part of the Coral Triangle, which contains some of the richest marine biodiversity on earth. Located in a biodiversity hotspot, the Derawan Islands feature 872 species of reef fishes, 507 species of coral, and invertebrates, including protected species (5 giants clam species, 2 sea turtles, coconut crab, etc.).

Derawan Islands have at least two lakes containing stingless jellyfish, one in Kakaban Island and the other in Maratua Island with Haji Buang Pond. Kakaban is more famous than the second, which is also more difficult to access. The lake in Kakaban consists of millions of jellyfish, ranging from small to large ones, some, twice as big as an adult's palm. Indonesia has at least 7 lakes with stingless jellyfish. Some others are located in: Raja Ampat, West Papua, Togean Island, Central Sulawesi and one in Rote Island, East Nusa Tenggara. [1]
There are two inhabited islands, namely Derawan (with a village of 1,259 people) and Maratua (comprising four villages with 2,704 people). Fishing is an important income-generating activity for the community. Since the early 1990s, people have caught live groupers, Napoleon wrasse, and lobsters, to fill high demand. There are three diving resorts in the Derawan Islands, while more additional resorts or facilities are in the planning process.
Maratua Island has an area of 35.5 square kilometers and has at least 13 caves, but the prediction is that there are more than a hundred caves which are not yet explored. The caves usually have connection directly to the sea. These caves originated from reef which sea water infiltrated into, creating underground channels. [2]

The Coral Triangle (CT) is a roughly triangular area in the tropical waters around the Philippines, Indonesia, Malaysia, Papua New Guinea, the Solomon Islands and Timor-Leste. This area contains at least 500 species of reef-building corals in each ecoregion. The Coral Triangle is located between the Pacific and Indian oceans and encompasses portions of two biogeographic regions: the Indonesian-Philippines Region, and the Far Southwestern Pacific Region. As one of eight major coral reef zones in the world, the Coral Triangle is recognized as a global centre of marine biodiversity and a global priority for conservation. Its biological resources make it a global hotspot of marine biodiversity. Known as the "Amazon of the seas", it covers 5.7 million square kilometres (2,200,000 sq mi) of ocean waters. It contains more than 76% of the world's shallow-water reef-building coral species, 37% of its reef fish species, 50% of its razor clam species, six out of seven of the world's sea turtle species, and the world's largest mangrove forest. In 2014, the Asian Development Bank (ADB) reported that the gross domestic product of the marine ecosystem in the Coral Triangle is roughly $1.2 trillion per year and provides food to over 120 million people. According to the Coral Triangle Knowledge Network, the region annually brings in about $3 billion in foreign exchange income from fisheries exports, and another $3 billion from coastal tourism revenues.
