Catostylus mosaicus, also known as the jelly blubber or blue blubber jellyfish, is a species of root-mouth jellyfish of the order root-mouth jellyfish. The jelly blubber is distinguishable by its colour, which ranges from light blue to a dark blue or purple, and its large (250–300 mm (9.8–11.8 in)), rounded bell which pulses in a staccato rhythm.
