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
  • About Heterobranchia order, ( Different - Kiemer ) JE Gray, 1840 Order heterostropha, (miscellaneous rotator ) P.H. Fischer, 1885
  • 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
  • Clade Neritimorpha
  • Clade Caenogastropoda
  • Clade Heterobranchia ( Mixed - Kiemer ) informal group Lower Heterobranchia
  • Informal group Opisthobranchia ( opisthobranchs )
  • Informal group Pulmonata ( snails )
