The golden jellyfish (Mastigias papua cf. etpisoni[1]) is a subspecies of spotted jellyfish (Mastigias papua) that inhabits Jellyfish Lake on Eil Malk island in Palau in the western Pacific Ocean.[2] 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.[3]
The golden jellyfish is morphologically, physiologically, and behaviourally distinct from the spotted jellyfish. It was described as a separate subspecies in 2011, together with four other new subspecies inhabiting nearby marine lakes. The species identification is uncertain (denoted by cf. in the name) because the individuals local to Palauan lagoons may be only one of several cryptic species that make up the M. papua group. It is distinguished by the almost complete loss of spots on the exumbrella and the almost complete loss of their clubs, an appendage attached to the oral arms.[4]
