Classifications of the acanthomorphs


Classification is one of the most fundamental parts of our understanding of the living world. Classifying is about rationalizing and designing boxes to organize our understanding of the world. Researchers working on classifications (they are called "systematists") do nowadays group species on the basis of lineage relationships: species that are together in a box are more closely related to each other than to species that are not included in the box (they share a more recent common ancestor than with species outside the box).


Trees and classifications

Classifications can be represented both by trees (left) or by boxes (right). Boxes illustrate the branches. On this website, you will find both type of representations, and both represent the relationships between the specimens. The two systems are equivalent, they deliver the same information.
