Phyllorhiza punctata
Taxonomic Group: Cnidarians-Scyphozoans


Phyllorhiza punctata is a rhizostome scyphozoan, with a large, conspicuous medusa stage. Most populations have medusae that contain zooxanthellae, symbiotic algae, which provide much of their nutrition through photosynthesis, and give the bell a brownish color. It was first described from Port Jackson, Sydney, Australia and its likely native range includes the Southwest Pacific from Thailand to New South Wales, Australia. Introduced populations have been found in North America (West, East, and Gulf coasts), Hawaii, the Caribbean, Brazil, and the Mediterranean. Large biomasses can develop in sheltered estuaries and lagoons, and occasionally in offshore coastal waters. This species has the potential for massive blooms, which could disrupt fisheries by clogging nets.
