Biological Teaching Collections

NCTC maintains collections of North American birds, fishes, and freshwater mussels for use in training.  The collections’ primary purposes are to support NCTC identification courses and to serve as a source of species information for the public through the National Digital Library (USFWS).  So far there are approximately 19,650 specimen records and the collection continues to grow.

Collection records include scientific and common names, collection locality, and a photograph of the specimen or a representative specimen of the lot (fish only).

We accept donations of specimens. For additional information and guidance, please contact the Science Lab Technician, Michele Atha at

Search Tips

Click on a collection link (e.g., 'Freshwater Mussel Collection'), to be taken directly to holdings listed within the National Digital Library.  All records within that specific collection will be displayed as images and corresponding metadata.

To make a query (order, family, genus, species, common name, or location), simply enter the information into the Search field.  Click on the 'Search' button, and all holdings for that taxon will be displayed. 

For searches that involve more than one species, sort by 'Title'.  For example, enter the genus Fusconaia in the Search field and leave the drop-down as 'within results'.  Click on the 'Search' button, and all collection holdings of Fusconaia will appear.  Sort by 'Title'. 

Click on any thumbnail image for an enlarged picture and the associated metadata.  Go back by clicking on the back arrow.  Now, run a new search for a particular species.  You MUST first delete 'Fusconaia' under the 'You’ve searched: Images' box, but leave 'freshwater mussels'.  Then, enter Elliptio jayenis into the Search field.  Click on the 'Search' button.  The Elliptio jayensis collection records will appear.
