Anuraeopsis miraclei, a new planktonic rotifer species in karstic lakes of Spain

  • Walter Koste
Article

Abstract

Two taxa of Anuraeopsis, A. fissa fissa (Gosse, 1851) and A. miraclei nov. spec. occur in meromictic and stratified karstic lakes in Spain. They coexist, but may also live separated in different strata with A. miraclei restricted to a zone near the chemocline, characterized by low temperatures and low oxygen concentrations. The two Anuraeopsis species differ from each other in size, shape, structure and thickness of the lorica, size of the trophi elements, shape of Weber's organ, and egg-structure.
