Zoophagus

Zoophagus is a genus of zygomycete fungi that preys on rotifers and nematodes. 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. thumb|alt=A hypha of Zoophagus insidians runs from the top of the image to the bottom of the image slightly left of center.
