  11. Identification do’s and don’ts • Do: • Always: 1000x, immersion oil • Well-contracted specimens! • External morphology • Carefull: watch out for: • Lorica ornamentation – use the “dry dorsal plate” trick • Cross section! • Don’t: • Squeeze the animals Hue University Rotifer Taxonomy workshop 6-12 March 2010

  12. Biogeography ? Some endemics Some cosmopolitan Hue University Rotifer Taxonomy workshop 6-12 March 2010

  13. Ecology • Marine: several, psammobiontic • Brackish water: several • Freshwater: the rest • Littoral • Psammobiontic • Habitat requirements: diverse • Feeding: browsersonbacteria film
