The following keyis intended for use by amateur microscopists
examining samples from the Great Lakes. This key not organized as
a standard dichotomous key. Instead, it is designed to allow comparison
of all groups at each taxonomic level (e.g., Family, Genus and Species
levels). For larger groups, some scrolling may be required to see
all descriptions on a page. This key is based on taxonomic and identification
information derived from the following sources:
- Zooplankton of the Great Lakes: A Guide to the Identification
and Ecology of the Common Crustacean Species. 1984. Balcer, MD,
NL Korda and SI Dodson. University of Wisconsin Press.
- Freshwater Invertebrates of the United States. Second Edition.
1978. Pennak, RW. John Wiley and Sons, Inc.
Key to Cladocerans (Crustacea) of British Columbia (includes
Great Lakes families except Cercopagidae)
