The tentacles also end in white spots. In addition to this symbiosis, the spotted jelly has several small mouths used to grab animal plankton. This spotted jellyfish averages about 18-20 inches in bell diameter however, researchers have found one with a 28 inch bell diameter off of the coast of North Carolina. Here, it found an ideal place to breed, free of their natural predators … Out of reach of predators, it has progressively lost its cnidocyte cells, and is therefore now totally harmless to scuba divers. White spotted jellyfish live in oceans and coastal waters. Of course it depends on where they live and their size.

Like corals, sea anemones, and other sea jellies, it belongs to the phylum Cnidaria. However, some individuals may contain some rare cnidocytes spread on the arms of the animal but they are inoffensive because they have lost their stinging power.[3]. Also known as the floating bell, Australian spotted jellyfish or Phyllorhiza Punctata. This is especially true where white-spotted jellies are an invasive species. The jelly swims almost 2 kilometres a day, following the sun, therefore allowing zooxanthellae living in its tissue to optimize their photosynthetic activity.

The spotted jelly lives in trophic mutualism with a unicellular organism capable of photosynthesis: zooxanthella. They will also consume them in all forms of their lifecycle. This mutualism is based on a life cycle which permits an exchange of energy between the two species. The content in this site was created from the following resources.

Any type of aquatic life that has a filtering system for finding plankton such as species of Whales will consume Jellyfish. But jellyfish also have a number of other natural enemies that like to eat them. In fact, in many locations the numbers of Jellyfish are higher than ever due to decreases in the population of their predators. Their niche mostly revolves around being both a predator and prey. Since these filter eating animals can consume very large amounts of prey every single day they are a very large predator of the Jellyfish. Many experts believe that the food chain balance of these various predators heavily relies on the presence of the Jellyfish. Jellyfishes with stinging tentacles are usually hunters.
