Standard Common Name

Jelly Blubber

Identification

In Sydney waters, the Jelly Blubber's large bell is a creamy white or brown colour, but farther north it is usually blue. This is because the jellyfish has developed a symbiotic relationship with algal plant cells that are kept inside its body. These plants vary in colour from region to region. The algae photosynthesise, converting sunlight into energy that can be used by the jellyfish.

Size range

35 cm

Distribution

Jelly Blubbers are found in Queensland, New South Wales and Victoria.

Habitat

Jelly Blubbers tend to be found in intertidal estuaries and coastal waters.

Feeding and Diet

The Jelly Blubber has no mouth but there are many tiny openings in its tentacles. The tentacles also have stinging cells that can capture tiny crustaceans and other plankton.
