![]() ![]() It can also be located near the surfaces of murky waters near estuaries in harbors and embayments. The jellyfish is native to the tropical western Pacific Ocean. The phyllorhiza punctata lives in warm temperate waters. EcologyĪ world map of the locations where the Australian Spotted Jellyfish has been sighted The study concluded the cause of this was linked to extended photoperiod and seasonal high water temperatures. One study concluded that small Western medusa and ephyrae grow in the early summer, but when researching in Brazil, they found that in the winter and spring, all sizes of Phyllorhiza punctata are present. Ephyrae develop into mature medusae over a period of usually several weeks. It may then either directly form additional scyphistoma through a process of budding, and/or develop into a strobila, a benthic form which asexually produces and releases young medusa known as ephyrae, detach from the ends of the sessile scyphistomae in a process termed strobilation. The planktonic planula larvae of the sexually reproducing medusa search out suitable settlement sites and leave the water column to normally settle to the bottom where it attaches and grows (which is the scyphistoma stage). The adult planktonic medusa is commonly referred to as a jellyfish. Sexes are separate in the medusae and these produce haploid gametes that combine through external fertilization to form free-swimming planula larvae. The scyphozoan reproductive cycle is typically dominated by the medusoid stage. This alternation of generations may facilitate the transport of jellyfish by shipping through ballast water (planktonic planula, ephyrae or medusa) or fouling (benthic scyphistoma or strobila). This way of reproduction is known as "alternation of generations". It involves an asexually reproducing polyp stage, alternating with a sexually reproducing medusoid stage (the "jellyfish stage"). The basic cnidarian reproduction cycle can be divided broadly into two parts. Shows the life cycle of a typical Jellyfish, including the Australian Spotted Jellyfish. They don't have well developed resiratory system but their skin is so thin on the body and tentacles that the oxygen flows through their body and goes through to their vital organs, carbon dioxide is removed the same way. They use muscle contraction of their bell, and muscular contraction of the tentacles to circulate seawater and nutrients. They excrete from their internal cavity, the coelenteron. They achieve movement by both floatation and relying on the oceans currents and winds. In most cases, adults release sperm and eggs into the surrounding water. They reproduce both sexually and asexually. ![]() The White Spotted Jellyfish has a simple digestive system with only one opening. It has radial symmetry with two germ layers which are the ectoderm(innermost layer) and the endoderm(outermost layer). The White-Spotted Jellyfish has a beautiful body with white spots over their body. Unlike some other jellies, the sting contains only a mild venom that does not cause a serious reaction in humans. Most jellyfish use their sting to hunt or for defense mechanisms. Each tentacle is covered with cells called cnidocytes that can sting or kill other animals. These jellyfish are a member of the Cnidaria family –“cnid” referring to the stinging barbs on their tentacles. This deprives other species such as corals, anemones, and some whales of their food source. They are generally found in large swarms which can threaten their local ecosystem because of the amount of plankton they filter from the water. They are native to Australia, but an invasive species in many other areas. The White-Spotted Jellyfish is a species of jellyfish known by the scientific name Phyllorhiza punctata. Jellies are measured in diameter from tip to tip.Different angle of Australian white spotted jellyfish ![]() Orbit 20, Neo 4, Omni 9, Omni 15, Neo 16, Medusa DesktopĬan be kept with other Rhizostomate jellyfish: Upside Down Jellies, Fried Egg Jellies, Blubber Jellyfish, Lagoon JellyfishĪll orders of live jellyfish will be shipped with our $38 priority flat rate service. Medium, Hardy but minor special requirements If you have never ordered live jellyfish before, please review how our shipping system works. We've kept many species here at the Jellyfish Warehouse, and these jellies certainly stand out to us. The golden brown symbiotic algae blends in with the rich blue color of the jellyfish, giving them a striking appearance. Their bells are covered with raised white spots and each arm is decorated with a white pointed tip. Similar in care and appearance to Spotted Lagoon Jellyfish but packed with fascinating personality. Phyllorhiza punctata roughly 1” round and 2” longĪ highly sought after and charismatic jellyfish native to the Indo-Pacific Ocean.
