[1] Bazinga rieki has a thick round translucent and colourless body, the aboral (upper) surface of which is covered in tiny warts with yellow centres.
It has a large circular stomach that takes up over half the jellyfish's body and is visible from underneath.
[1] Marine biologists Lisa-Ann Gershwin and Peter Davie described the jellyfish in June 2013, from the holotype, which was collected in shallow water in the Brunswick River in northern New South Wales at high tide.
The specific epithet refers to Denis Riek, who photographed a specimen in northern New South Wales, leading to the discovery.
The genus name, Bazinga, has two cultural references: firstly, as a colloquialism meaning "fooled you!"
