Animal superfamilies

The Filarioidea are a superfamily of highly specialised parasitic nematodes. Species within this superfamily are known as filarial worms or filariae (singular filaria). Infections with parasitic filarial worms cause disease conditions generically known as filariasis. Drugs against these worms are known as filaricides.

Geoplanoidea is a superfamily of freshwater and land triclads that comprises the species of the Geoplanidae and the Dugesiidae families.

Planarioidea is a superfamily of freshwater triclads that comprises the families Dendrocoelidae, Kenkiidae and Planariidae.

Metridioidea is a superfamily of sea anemones in the order Actiniaria. Members of this clade live in shallow subtropical waters worldwide.

Actinioidea is a superfamily of sea anemones in the order Actiniaria.

Tylenchoidea is a superfamily of roundworms. Its members are either plant parasites or detritivores.

Thelazioidea is a superfamily of spirurian nematodes in the large order Spirurida. Like all nematodes, they have neither a circulatory nor a respiratory system.

Actinostoloidea is a superfamily of sea anemones in the order Actiniaria.

The Mormyroidea (synonymy: Mormyriformes) are a superfamily (formerly an order) of fresh water fishes endemic to Africa that, together with the families Hiodontidae, Osteoglossidae, Pantodontidae and Notopteridae, represents one of the main groups of living Osteoglossiformes. They stand out for their use of weak electric fields, which they use to orient themselves, reproduce, feed, and communicate.

Habronematoidea is a superfamily of spirurian nematodes in the large order Spirurida. Like all nematodes, they have neither a circulatory nor a respiratory system.

Teleosauroidea is an extinct superfamily of thalattosuchian crocodyliforms living from the Early Jurassic to the Early Cretaceous. It is phylogenetically defined by Mark T. Young and colleagues in 2024 in the PhyloCode as "the largest clade within Thalattosuchia containing Teleosaurus cadomensis, but not Metriorhynchus brevirostris". This group contains two main families, the more piscivorous and gracile Teleosauridae and the more macropredatory and robust Machimosauridae.

The Schistosomatoidea are a superfamily of digenetic trematodes.
