The jelly blubber (Catostylus mosaicus), also known as the blue blubber jellyfish, is a species of jellyfish from coastal regions in the Indo-Pacific. It is the most commonly encountered jellyfish along the Australian eastern coast and large swarms sometimes appear in estuarine waters.
In Sydney waters, the jelly blubber's large bell is a creamy white or brown colour, but farther north in Australia it is usually blue.[1] The colours are derived from symbiotic algal plant cells within the body of the jellyfish.[2][3] There is no obvious mouth on the underside, but there are small openings on each arm, through which food is passed to the stomach.[4] The tentacles also have stinging cells that can capture tiny crustaceans and other plankton. It can grow up to 35cm across.[2]
The sting can be painful but generally poses no serious risk to humans.
This jellyfish is found in coastal parts of the Indo-Pacific. In Australia, it occurs off the coasts of Queensland, New South Wales and Victoria. It can also enter intertidal estuaries.[5]
Eats mainly plankton, small fish, some crustaceans, and small particles in the ocean water.
