These predators solely inhabit the open ocean. Phyllorhiza punctata has become an issue in the Northern Gulf of Mexico near the Mississippi Sound affecting zooplankton levels. In Brazil, the Each jellyfish can clear 50 cubic meters of water filled with plankton in one day, making dense aggregations of Australian spotted jellyfish dangerous because they can alter food webs in the water column. salinity regime in western Australia.

Thereafter the specimens were collected with a hand net and transfer red to a 30 1 glass aquarium. negatively impact the ability of P. punctata to thrive. Their venom is not potent enough to kill their prey which is why they are filter feeders. 2003).

Predation on jellyfish by the cephalopod Phyllorhiza punctata is a large jellyfish with a rounded and somewhat flattened gelatinous bell that is clear or possibly tinted brown with many small white crystalline refractive spots close to the surface (Graham et al. before rapidly declining (graham et al.

Thereafter the specimens were collected with a hand net and transfer red to a 30 1 glass aquarium. It may have hitched a ride in ships' ballast tanks, travelling from Australia and the Pacific region to the Caribbean.

Submit additional information, photos or comments 5 2 25. Besides knowing that low salinity causes P. punctata to lose their symbiotic algae, there isn’t much known on how to manage these jellyfish populations; especially since they are found in wide open ocean areas. Invasive Marine and Estuarine Animals of the Gulf of Mexico. They have only a mild sting and their venom isn’t toxic or a threat to humans. 116114).Swims near the surface in murky waters near estuaries in harbors and embayments (Ref. different in appearance otherwise.

Economic implications of the tropical jellyfish, Phylloriza punctata, in Species Name:  and Nogueira 2006). The Australian Spotted Jellyfish is native to the southwestern Pacific, where it feeds primarily on various snail species. Though some degree of euryhaline tolerance is expected in an southern population of this non-indigenous jellyfish (Fuller 2005, Ecological and accidental transport by the shipping industry, or perhaps an irruptive The Australian Spotted Jellyfish (Phyllorhiza punctata) is also known as the White-spotted jellyfish.

Medusae of P. punctata contain dense concentrations of zoo-xanthellae, but those of C. mosaicus contain few or no zooxanthellae (R.
