The Irukandji jellyfish is one of the most venomous jellyfish in the world. It is very small, usually 5-10mm wide, but its venom is extremely powerful, 100 times more potent than a cobra's venom. Little is known about its life cycle due to its small and fragile nature. It is believed to reproduce similar to other jellyfish, starting as an egg that develops into a polyp then buds off ephyra that mature into adult jellyfish. Their sting can cause excruciating "Irukandji syndrome" within 30 minutes of the sting.
