Finfish in the Rano Kau Caldera of Easter Island

The Rano Kau Caldera is the largest inactive volcano on Easter Island. This Chilean island, a triangle of volcanic rock located 2,600 miles west of Santiago, is the most remote of all populated islands on our planet. Rano Kau is located on the southwestern tip of the island. Its crater is the basin of a large freshwater lake. As part of the cooperative expedition undertaken by the National Park Service of the United States and CONAF of Chile, fish specimens were collected from the Rano Kau Caldera and brought back to the United States for identification and study.
