About this site
Same Ana (サメ穴) is a shallow site of several rocks a three-hour boat run from Chichijima in the Ogasawara Islands, Tokyo, with a maximum depth of 14 m and an average around 10 m. Sand tiger sharks sometimes lie inside its hole, and many tunnels make the site maze-like; whitetip reef sharks and drummers are also seen. It is unusually shallow for the Keita island group; current runs at times and the site is for advanced divers only.
