There is one small, barren and uninhabited islet, Ngaruangel Island, in the center of the eastern rim of the atoll, at its easternmost point. Ngaruangel Island is 200 m long north-south, and from 65 m wide in the south to 105 m in the north. There is a sand spit attached to the island, pointing southwest into the lagoon, 75 m long and 20 m wide. The total area of the island is 1.5 ha.

The islet consists almost entirely of pieces of rough coral rock thrown up by surf. Most of the pieces are rough or sharp and are largely of the Acropora reticulata type, or of similar form. Sand and sandy gravel are limited to the lagoon side and the southern tip. The altitude is a little less than one meter above high tide.

There is no vegetation on the islet. Animal life is represented by numerous marine crane flies, probably Limonia, subgenus Dicranowia. Terns are abundant.
