Characteristics A separate window opensReferences

These are the waters in the vicinity of the Kerama Islands. The Kerama Islands are a leading region where rare species are identified, with fringing coral reefs and a high degree of diversity of species. Corl of these are an important source of larva on the coral reef in Nansei islands (Ministry of the Environment, 2001). Coral reefs are distributed densely in these highly transparent waters. The waters in the vicinity of Yakabijima Island and Kubajima Island are both important green turtle and loggerhead turtle spawning grounds and home to a valuable ecosystem in which the Ryukyu odd-tooth snake (a species of Colubridae) come down to the shore to eat hatchlings of sea turtles. They also are a feeding ground for green turtle and hawksbill turtle (Ministry of the Environment, 2001; Kamezaki, Taniguchi, 2013; Miyahira et al., 2000; Tomiyama and Miyahira, 2007). These also are important waters where humpback whales raise their young in the winter (Ogasawara Maritime Center and Kato, 2002; Calambokids et al., 2001).

* This is the species list of which meet the criteria. In that matter, this list does not include all species that inhabit the individual area.
Abbreviation in the information is as follows.
[Br/Ne] : Adjacent water of breeding area or nesting site
[Sp] : spawning area
[Ad] : species not used for analysis but add to the list because inhabit information was collected later
[Ex] : species used for analysis but considered to be possibly extinct in the EBSA region (area)
No mark : data of species distribution
