Phyllorhiza punctata is a species of jellyfish, also known as the floating bell, Australian spotted jellyfish, brown jellyfish or the white-spotted jellyfish. It is native to the western Pacific from Australia to Japan, but has been introduced widely elsewhere. It feeds primarily on zooplankton. P. punctata generally can reach up to in bell diameter, but in October 2007, one wide, perhaps the largest ever recorded, was found on Sunset Beach, North Carolina. Description True jellyfish go through a two-stage life cycle which consists of a medusa stage (adult) and a polyp stage (juvenile). In the medusa stage, male jellyfish release sperm into the water column and the female jellyfish gathers the sperm into her mouth where she holds the eggs. Once fertilization occurs and larvae are formed they leave their mother and settle to the ocean floor. Once on the bottom a polyp form occurs and this form reproduces asexually by "cloning" or dividing itself into other polyps. Jellyfish can live for up to five years in the polyp stage and up to two years in the medusa stage (active). When found in warm waters these jellyfish flourish. They are mostly euryhaline but low salinities may have a negative effect on the species. In times of low salinity, these jellyfish exhibit loss of their zooxanthellae. Their dispersal patterns are locally patchy. They have only a mild venom and are not considered a threat to humans. They have a mild or non-noticeable sting which can be cured with dilute acid. (Usually white or cider vinegar) Ecology The Phyllorhiza punctata is a part of the Rhizostomatidae family and the genus Phyllorhiza. Their venom is not potent enough to kill their prey which is why they are filter feeders. Their main food source is zooplankton. Normally they travel in large groups, which tends to result in huge swaths of them consuming all of the zooplankton in the area. This leads to detrimental impacts for the local ecosystem in which they travel through. Since they eat all the zooplankton, there is a lack of food for the other species relying on the plankton as their food source. Their native distribution is around Cairns, Queensland, Australia, and Thailand. Having its native habitat extend north from eastern Australia up to South East Asia. They have also been found in non-native regions such as Western Australia, United States, the Atlantic Basin, Brazil, Puerto Rico, the eastern Mediterranean,
