Most of the species in the family Planctomycetaceae are of interest for their eukaryotic-like cell structures and characteristics of resistance to extreme environments. Here, we report draft genome sequences of three aquatic parasitic species of this family, Singulisphaera acidiphila (DSM 18658T), Schlesneria paludicola (DSM 18645T), and Zavarzinella formosa (DSM 19928T).
