Also known as the “Jelly Blubber”, C. mosaicus is a species of Catostylid jellyfish which is widely distributed throughout coastal areas in the Indo-Pacific, including Australia. Catyostlus mosaicus is a fairly commonly encountered species and can occur in large swarms at times. Like most jellyfish C. mosaicus uses stinging nematocysts to dispatch its prey which typically consists of small fish and zooplankton. C. mosaicus has several color morphs with more southern individuals possessing a white or brown color and northern individuals sporting a distinct blue color.
Also known as the Blue Blubber Jellyfish, the jelly blubber is a species of jellyfish that is native to the coastal regions of the Indo-Pacific. They usually remain in the coastal regions but can be found in intertidal estuaries as-well. Like most jellyfish the jelly blubber, despite its threatening name, is a predator and will feed on plankton, fish, and small crustaceans using its stinging nematocysts to dispatch its prey. These stinging tentacles can be very painful but will not cause death in humans.
