Sydney Aquarium - The Experience []

The hierarchy of the 7 categories in the classification system is thus: Kingdom Phylum Class Order Family Genus Species The further down the hierarchy you go, the more closely related the organisms in that category. For example: there is a greater level of diversity between organisms in a class than there is in a family. Organisms in a species have the most features in common.
