Polymorphism in a local population can be an adaptation to prevent density-dependent predation, where predators preferentially prey on the most common morph.a form of body symmetry in which the parts of an animal are arranged concentrically around a central oral/aboral axis and more than one imaginary plane through this axis results in halves that are mirror-images of each other. Irukandji jellyfish are small and colorless, making them difficult to find. They do this quite often and the trailer 2010. Individuals of this species typically reach 25 mm in diameter, however it has been documented at a diameter of 35 mm. 1.
