Heterobranchia
Representative examples of Heterobranchia
Heterobranchia is the scientific name for the screw - About ordering of Verschiedenkiemer This superorder is a key taxon in the classification of snails ( gastropods ), which includes not only many, but also very different kinds of marine, freshwater and terrestrial snails. Since JE Gray (1840 ) is known, enter the Heterobranchia in adapted form in modern taxonomy of the worm on, most recently as a superorder in Ponder & Lindberg (1997 ) and as a clade in the current taxonomy of Bouchet & Rocroi ( 2005).
System
Taxonomy of Ponder & Lindberg (1997)
In the scheme of Ponder & Lindberg (1997) the Heterobranchia escape to the outside as a superorder. Internally, there is a dichotomy
- Class Gastropoda ( snails) G. Cuvier, 1797 Subclass Orthogastropoda ( True snails)
- Subclass Apogastropoda, L. Salvini - Plawen & G. Haszprunar, 1987 Superorder Caenogastropoda, Cox, 1960

- Order Opisthobranchia ( opisthobranch ), H. Milne Edwards, 1848
- Order Pulmonata ( snails ), G. Cuvier in HMD de Blainville, 1814
Taxonomy of Bouchet & Rocroi (2005)
In the taxonomy of Bouchet & Rocroi (2005) the Heterobranchia escape to the outside than a Cladus. Internally there is a tripartite division
- Class Gastropoda Clade of extinct Paleozoic molluscs with unsecured assignment
- Extinct clade basal taxa with assured assignment to the worm
- Clade Patellogastropoda ( limpets )
- Clade Vetigastropoda
- Clade Cocculiniformia
