Distribution

States

Northern Territory, South Australia, Tasmania, Victoria, Western Australia

Extra Distribution Information

Originally described from South Australia, this species was subsequently reported in Western Australia by Thiel (1926), Northern Territory by Kramp (1965), Victoria by Fancett (1986) and Tasmania by Edgar (1997). It is one of the commonest and most conspicuous jellyfishes in temperate Australian waters. Curiously, it does not seem to have made its way along the eastern seaboard.

Ecological Descriptors

Carnivorous, marine, neritic, planktonic.
