The White Spotted Jellyfish are native to Australia and have migrated to many other areas.  They have just one opening in their digestive system.  They are able to move by floating and reliance on ocean currents and winds. In order to circulate seawater and nutrients they use muscle contraction of their bell and  tentacles. The White Spotted Jellyfish has 2 stage life cycle. The first stage is the polyp (juvenile) stage and then the medusa (adult) stage.  They are filter feeders because they don't contain enough venom in their tentacles to kill prey.      

Taxonomic Breakdown:

Species:punctata Genus:Phyllorhiza Order:Rhizostomeae Class:Scyphozoa Phylum:Cnidaria Kingdom:Animalia

Conservation & Helping:

The White Spotted Jellyfish is a threat to different species of shrimp. They consume massive amounts of plankton, eggs and larvae which is causing an issue for the fishing industry. They also got tangled up in fishing nets and can ruin fishing gear. The consumption of large amounts of plankton are causing other marine animals to not have enough to eat. As of now, nothing is being done to remedy the situation.
