The island was formed by volcanic action which left a curved and complex coastline. Coastal beach terraces and cliffs drop to colorful coral reefs where schools of tropical fish make their abode. Along the shoreline, white coral beaches can be found and numerous coves which lead into warm tropical waters.
Surveys show that the island is home to more than 300 species of fish, with reef fish being the most abundant. Most of these fish are brightly colored in complicated patterns; and the sight of these beautiful fish flitting among the coral, which itself vies for attention with a multitude of shapes and shades, forms a wildly colorful undersea tableau.
Warm, clear, shallow seas provide an ideal environment for the growth of coral. Green Island is surrounded by this kind of excellent ocean environment, and thus has produced a beautiful world of coral. There are a large number of coral species here, and their ratio of cover is high; everywhere, you can see cityscapes of coral flourishing under the waves. There are also a large number of shellfish and crustacean species, and the huge quantities of miniature shellfish along the shoreline is one of the unique features of the island. More than four species of sea snakes thrive in the waters off the western side of the island; they have a gentle nature but are also equipped with strong poison, so wise skin-divers maintain a safe distance from them.
Shihlang Diving Area is close to the most bustling Nanliao Village on the island and is the most famous diving site on Green Island. Here coral reefs are gentle, and intertidal zone is long. Whether snorkeling or deep diving is very suitable here. Farther inside the ocean, you can visit the largest mushroom under the water—“mushroom coral.” It is the world’s largest Porites coral, estimated over 1,200 years old. What a spectacular view!
