Also widely found are parrotfish, tuna and mantas. This is one of the reasons why this island is a scubadiver's paradise. The most numerous plant species are the cupey, the endemic Euterpe macrospadix palm, and huriki. Ferns, bromeliads, and selaginellas are also very abundant. The three endemic bird species are the Coco Island cuckoo.
