Ctenophora

Ctenophora (del greco ancian ktenos 'pectine (en)' et phorein 'portar') es un phylo de animales marin con circa 1000 species. Illos es notabile per le gruppo de cilio (evocante un pectine) utilisate pro natar.

Secundo un studio de 2023, Ctenophoros serea le gruppo le plus basal de animales actual (mesmo si spongias parece minus complexe):^[7]

	Cnidaria

	Placozoa

Bilateria

Secundo iste nove cladogramma, le subregno Eumetazoa perde su legitimitate.

Phylogenia interne[modificar | modificar fonte]

Phylogenia intra Ctenophora:^[8]

Ctenophora

Mertensiidae (Cydippida)

Platyctenida

Pleurobrachiidae (Cydippida)

	Lobata

	Thalassocalycida

	Cestida

	Haeckeliidae (Cydippida)

	Beroida

Le ordo Cydippida se revela polyphyletic, dunque non valide.
