The freshwater zooplankton are comprised of three major groups of inverte.te metazoans: the rotifers, copepods, and cladocerans. The copepods and cladocerans are both groups of the large subphylum Crustacea, and are not included on this web site. P.os and further information for these groups can be found at .A GUIDE TO IDENTIFICATION OF ROTIFERS,. CLADOCERANS AND COPEPODS FROM. AUSTRALIAN INLAND WATERS. R.J. SHIEL. Murray-Darling Freshwater Research Centre. Co-operative Research Centre for Freshwater Ecology. Identification Guide No. 3. Presented at the Taxonomy Workshop held at..At left, you can see a p.omicrograph identifying basic anatomical features of Epiphaneschionus. The general body plan of a rotifer consists of four basic regions: head, neck, trunk body , and the foot. In most species, the head carries a corona crown of cilia that draws a vortex of water into the mouth, which the rotifer .
Identification of rotifers should proceed with the use of taxonomic keys. A key to the families of freshwater Rotifera can be found in Wallace and Snell 2001 and genera can be identified using Edmondson 1959 or Stemberger 1979 . For identification of species, see Ruttner-Kolisko 1974 and Koste 1978 ..Rotifers are an ecologi.y and morphologi.y diverse group of small multicellular inverte.tes body length: 0.03 - 2 mm that are common to all aquatic and moist, terrestrial habitats. In creeks and rivers, rotifers are one of the species-richest inverte.te group, reaching high abundances often deep in the inters.ial sediments 1-4..The rotifers Rotifera, commonlyed wheel animals make up a phylum of microscopic and near-microscopic pseudocoelomate animals. They were first described by Rev. John in 1696, and other forms were described by Antonie van Leeuwenhoek in 1703..Introduction to the Rotifera Rotifers : At left, you can see a p.omicrograph identifying basic anatomical features of Epiphaneschionus..
