Scientific name : Phyllorhiza punctata
Family : Mastigidae
Distribution : Western Pacific
Biology : This jellyfish is recognisable by its bluish-brown umbrella with white spots. It can measure up to 50 cm in diameter with a record of 70 cm. It has been accidentally introduced into the Gulf of Mexico in the ballast water of ships, where it is considered an invasive species.
It feeds mainly on zooplankton, fish eggs or larvae and small fish.
It has photosynthetic cells, called zooxanthellae, which enable it to transform light into oxygen and nutrients, which it feeds on.
Its sting, although harmless for humans, can be stinging if there is a large quantity of the jellyfish.
