Starting on top with the broadest level of taxonomy, is the domain. Hirudio medicinalis belongs to the domain, eukarya, meaning the cells making up the leech have a true nucleus and membrane bound organelles. Most organisms that people are familiar with belong to this group, including all animals, plants, and fungi. The next level of classification is the kingdom. Hirudo medicinalis belongs to the Animal Kingdom, which is characterized by organisms that are heterotrophic, multicellular, and lack a cell wall. Generally speaking, most animals have some type of mobility. They also lack plant characteristics like chloroplasts and chlorophyll. Hirudo medicinalis belongs to the phylum, annelida.
