''Zoophagus'' is a
genus of
zygomycete fungi that preys on
rotifer
The rotifers (, from the Latin , "wheel", and , "bearing"), commonly called wheel animals or wheel animalcules, make up a phylum (Rotifera ) of microscopic and near-microscopic pseudocoelomate animals.
They were first described by Rev. John H ...

s. It was established in 1911 by Sommerstorff, who originally considered it to be an
oomycete. It is common in a variety of freshwater habitats, such as ponds and sewage treatment plants.
Morphology
The
mycelium is composed of non-septate hyphae that bear lateral adhesive pegs. Spores are sometimes septate long, fusiform merosporangia with tapered ends that are borne on lateral sporangiophores.
Ecology
''Zoophagus'' species have been reported from ponds, brooks, and fens, usually in association with algae or decaying plant matter.
Exceptions are ''Z. cornus'', which was described from rice paddy mud, and ''Z. pectosporus'', which was described from moss and additionally reported from leaf litter. ''Zoophagus insidians'' in particular has also been reported from sewage treatment plants where it can pose a significant threat to water quality. ''Zoophagus'' spp. prey on a variety of rotifer species.[ ''Zoophagus pectosporus'' primarily preys on nematodes and seems to be restricted to species of ''Bunonema'', though it is also capable of trapping rotifers.] When prey encounter one of the traps, an adhesive is released and the animal is caught. Hyphae later grow into the body and digest it.[
