Characteristics A separate window opensReferences

These are the waters in the vicinity of the Danjo Islands (an island group in the South China Sea located southwest of the Goto Islands). Formed of welded tuff, the Danjo Islands are characterized by their coast of sea cliffs. They are home to a valuable natural environment in terms of geology and minerals, flora, and fauna, and they include breeding grounds for groups of birds including streaked shearwater and Japanese murrelet. Since they also are home to breeding colonies of Japanese murrelet (an IUCN endangered species) they are designated an Important Bird (IBA) (BirdLife International, 2012).
