AUSTRALIAN SPOTTED JELLYFISH or WHITE SPOTTED JELLYFISHPhyllorhiza punctata ©cheesekid
This gorgeous shot was taken at the Monterey Bay Aquarium 
Phyllorhiza punctata is a species of jellyfish, also known as the Australian spotted jellyfish or the White-spotted jellyfish.  It is native to the southwestern Pacific, where it feeds primarily on  zooplankton. P. punctata average 45-50 cm in bell diameter but there had  been a maximum reported size of 62 cm. However, in October, 2007, one  72 cm. wide, perhaps the largest ever recorded, was found on Sunset  Beach, NC. In July 2007 smaller ones were seen in Bogue Sound much  further north along the North Carolina Coast. They have only a mild  venom and are not considered a threat to humans. However, their ability  to consume plankton and the eggs and larvae of important fish species is  cause for concern. Each jellyfish can filter as much as 13,200 gallons  of sea water per day. While doing that, it ingests the plankton that  native species need.
True jellyfish, Phylum Cnidaria, 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.
