Caño Island National Park has been established as a protected national park as a part of the Osa Conservation Area, with a permanent ranger station on the island. It is a popular tourist destination for ecotourism such as whale watching, attracting visitors for its beaches, coral beds, and sea life. Researchers currently use the coral beds to study the factors surrounding coral death and recolonization. Marine life includes manta rays, dolphins, false killer whales,[3] sea turtles, whales, a wide variety of fish, and possibly manatees as well. The nudibranch Mexichromis tica was described from here and Darwin Island on the Galápagos Islands in 2004. The limited diversity of terrestrial fauna, however, is noticeable, with the island having less than one percent of the insect diversity of the peninsula and an absence of numerous animals native to the nearby mainland. Evidence of pre-Columbian human activity on the island is substantial, with some of the most interesting artifacts being stone spheres evidently carved by early civilizations.
