Phyllorhiza punctata is the scientific name for the white-spotted jellyfish, also know as the floating bell jellyfish or the Australian white-spotted jellyfish. Today, there are known populations of white-spotted jellyfish in Hawaii, Puerto Rico, Gulf of Mexico, Brazil, and most recently, in the Mediterranean.

White-spotted jellies have very mild venom and do not pose a threat to human beings.

The fact that the first documented occurrence of the species in event within an extant cryptic population. southern population of this non-indigenous jellyfish (Fuller 2005, Abundance: 1984). White-spotted jellies are native to the warm, tropical waters of the western Pacific Ocean, from Oceania through East Asia. Jellyfish can live for up to five years in the polyp stage and up to two years in the medusa stage. Scyphozoans have a life cycle that can be broadly divided into two Native Range: Phyllorhiza punctata is indigenous to the tropical western Pacific Ocean (Graham et al. 2011. Fuller P. 2005. 2005. Phylum Cnidaria Class Scyphozoa Order Rhizostomeae Family Magistiidae.
