                                   Five Kingdom Classification Early biologists classified all species as either plants or animals. Since this method makes it difficult to research specific creatures, American taxonomist R.H. Whittaker created the five-kingdom classification in 1969. This system divides all organisms into groups based on how they are organized and how they are fed. Important standards for this classification include - The complexity of cell structure i.e. Prokaryotic and Eukaryotic. The complexity of the Organisms body is Unicellular and Multicellular. Mode of nutrition Autotrophs and Heterotrophs. Lifestyle. Phylogenetic Relationship. Based on these criteria, Whittaker classified the living world into the following categories  - Kingdom Monera                 Kingdom Protista Kingdom Fungi Kingdom Animalia Ki...

Their body color changes based on what they eat, so they can be blue, pink, or other colors. Let's learn more about Aurelia in detail.
