Due to a high variety of corals and wildlife in the area, the Blue Corner is a popular recreational dive site. It is variously called "the most requested dive in Palau" and "one of the most action-packed scuba dive sites in the world."
The golden jellyfish is a subspecies of spotted jellyfish that inhabits Jellyfish Lake on Eil Malk island in Palau in the western Pacific Ocean. Like the nominate subspecies, it derives part of its nutrition from symbiotic algae (Zooxanthellae) that live in their tissues and part of their nutrition from captured zooplankton.
