Jelly Blubber

Description:

Quite a big jelly. Maybe 25cm in diameter? 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. 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. Its bell pulses in a distinctive, staccato-like rhythm. There is no obvious mouth on the underside, but there are small openings on each arm, through which food is passed to the stomach. The tentacles also have stinging cells that can capture tiny crustaceans and other plankton. It grows to a diameter of 35 centimetres (14 in). The sting can be painful but generally poses no serious risk to humans.

Habitat:

Australian Estuary Smiths lake, NSW

This jellyfish was unfortunately dead
