The seawater here is unpolluted and clear. It is an excellent place for snorkeling. Different sea areas have their own characteristics: some are situated on magnificent coral reefs, some are habitats of colorful fishes, and the seawater in the same area shows different colors due to the contrast of different marine organisms. Because of the exuberant parasitism of seafloor corals around the elephant island, there are many golden and silver tropical fish swimming among the coral bushes.
