The underwater world in Bali offers a great variety of species. Located in the southwestern part of the coral triangle, the richness of the coral reefs is unique. More than 3.500 species have been discovered here. The Indonesian current is in charge of transporting plankton to the reefs around Bali. This very important current transports the water from the Pacific Ocean, via Java and Banda Sea, to the Indian Ocean. This optimal geographic situation guarantees the great diversity of fish, coral, and critters; including nudibranchs, rhinopias, ghost pipe fish, cowries, boxer crabs, mimic octopus, wonderpus and many more.
