The islet is a volcanic seamount and features rocky coastlines. It is mostly barren but has some scattered vegetation.[1]Large colonies must have existed formerly as the island has thick layers of guano. Its length is 2.3 km (1.4 mi) from southwest to northeast and the width is approximately 1.1 km (0.7 mi) from southeast to northwest. The island is an integral nature reserve.[2]
