Hikkaduwa National Park is one of the three marine national parks in Sri Lanka. The national park contains a fringing coral reef of a high degree of biodiversity. There are 31 species of coral found and 170 species of reef fish. These include crabs, shrimp, ornamental fish, oysters, sea worms. Porites Desilveri is a species of coral native to Sri Lanka, while Chlorurus Rhakoura and Pomacentrus proteus are the two endemic reef fish species in Sri Lanka. You'll have to rent glass-bottomed boats to watch them. These are located at a depth of about 50 meters and give you easy arrive and see.
To reduce the effects to the ecosystem, the reef was declared a national park on September 19, 2002.
