Mastigias sp. 1
Taxonomic Group: Cnidarians-Scyphozoans


Mastigias sp. 1 is a rhizostome scyphozoan, with a large, conspicuous medusa and a small polyp stage. Rhizostome jellyfish of the genus Mastigias are widespread in the Indo-Pacific and they are most abundant in marine lakes on the islands. Mastigias sp. 1 was first identified from Kakaban Island, off Borneo, Indonesia, where the jellyfish are a tourist attraction for divers. A molecular comparison of 12 Mastigias populations found that Mastigias sp. 1 was most similar to introduced populations in Florida and Puerto Rico. Impacts have not been reported from introduced locations.
