Lophotrochozoa (/ləˌfɒtroʊkoʊˈzoʊə/, "crest/wheel animals") is a clade of protostome animals within the Spiralia. The taxon was established as a monophyletic group based on molecular evidence.[2][3]

Groups

See also: List of bilaterial animal orders

The Lophotrochozoa has basal Cycliophora and Mollusca groups, and more derived Lophophorate, Nemertea and Annelida groups.[4][5]

With the introduction of Platytrochozoa and Rouphozoa, one candidate phylogeny is pictured below – though other studies recover a range of different alternative possibilities:[6][7][8][9][10][11][12][13]

Protostomes

A number of fossil taxa can be identified as early Lophotrochozoans, even if their precise affinity remains contested.
