Leeches underline the need for linnaean taxonomy

A proposal for a systematic classification of airway devices similar to the Linnaean taxonomy.

The Linnaean Hierarchy and the Evolutionization of Taxonomy, with Emphasis on the Problem of Nomenclature

During the post-Darwinian history of taxonomy, the Linnaean hierarchy has maintained its role as a means for representing hierarchical taxonomic relationships. During the same period, the principle of descent has taken on an increasingly important role as the basis for reformulated versions of fundamental taxonomic concepts and principles. Early in this history, the principle of descent provide...

Leeches

Real worms don't eat bacteria. Leeches are segmented, eucoelomate worms of the phylum Annelida, distinguished from other annelids by anterior and posterior suckers used for locomotion and feeding — on blood or soft body parts of other animals. They are not to be confused with nematodes, which lack these (and most other) features. Leeches are mainly aquatic, but the Asian land leeches are well k...
