Jellyfish restored: they eat fish eggs and juvenile fish, and compete with fish for food, preventing fish stocks from recovering. Some small fish are immune to the stings of the jellyfish and live among the tentacles, serving as bait in a fish trap; they are safe from potential predators and are able to share in the fish caught by the jellyfish.

Jellyfish form large masses or blooms in certain
Bazinga (jellyfish) Bazinga (jellyfish) Bazinga is a genus of rhizostome jellyfish with only one known species, Bazinga rieki, found off the central eastern coast of Australia.

The specific epithet refers to Denis Riek, who photographed a specimen in northern New South Wales, leading to the discovery. "Bazinga rieki" could not be placed in any known family or suborder of rhizostome jellyfish, so a new family Bazingidae was erected; it
