It is largely sunk, only in the west the fringing reef penetrates the water surface and forms with Pratas Island (2.8 km × 0.9 km; 1.74 km²) the only significant land mass.
The islands were occupied by Japan from 1907 to 1909 and from 1939 to 1945 . Today they are under the control of the Republic of China in Taiwan and are inhabited by only about 200 marines stationed there .
