Home > Coral Photo Gallery > Ishigaki
Ishigaki Island is the third-largest island in the Ryukyu Archipelago, after Okinawa Island and Iriomote Island, with an area of approximately 222 km². The island is roughly pentagonal in shape, with the elongated Nosoko Peninsula and Hirakubo Peninsula extending toward the northeast. Coral reefs are developed along the entire coastline. In particular, the sea area between Ishigaki Island and neighboring Iriomote Island to the west is known as the Sekisei Lagoon, where numerous smaller islands, including Taketomi Island and Kohama Island, are scattered. This lagoon supports extensive shallow-water coral reefs with exceptionally high biodiversity. On the southeastern coast, Shiraho Reef is renowned as a habitat for more than 120 coral species and for its large colonies of blue coral (Heliopora coerulea).
By examining the coral reefs surrounding the entire island, this photographic archive may reveal whether differences exist in the coral genera that compose these reefs in relation to biogeographic factors, such as contrasts between the northern and southern coasts or between the eastern and western sides of the island. We hope that these photographs will provide new insights into the diversity and distribution of coral reef communities around Ishigaki Island.
