Continenticola
Continenticola is a clade that includes the land planarians (Geoplanidae) and the freshwater triclads (Dendrocoelidae, Dugesiidae, Kenkiidae and Planariidae).

Phylogeny
On the basis of molecular evidences, Carranza and colleagues suggested in 1998 that the families of freshwater and land flatworms must be grouped together in a monophyletic group that they coined Continenticola. This grouping was accepted by Ronald Sluys in 2009. Despite the molecular evidences, there are no morphological apomorphies supporting this clade.[2]

gollark: I mean, you can go without oxygen input for a few minutes (I think because of stuff held in the lungs, though - stopping time would break absorption of that), but stuff does actually need it.
gollark: You can't just "not require oxygen".
gollark: The air doesn't move, so you're fixed in place (by air), but also can't breathe any.
gollark: If you stop time for everything but you, you can't actually do anything and rapidly suffocate or something.
gollark: It's not well-defined. If you literally "stop time", it can never start again.
