If you worked for Fisheries and Oceans Canada and found a mussel shell
in a river, how would you go about identifying it quickly and accurately? Activity:
1. Working with a small group of colleagues, use your field guide to identify your
2. Write down the number on the shell and your proposed identification
(common name, species name, field guide page #).
These shells are the property of the Department of Integrative Biology
? and were collected under permit. Many of them are endangered.
It is illegal to possess these shells without a permit.
So please BE CAREFUL and BE SURE TO RETURN THEM!

2. What was the biggest challenge to getting a
correct identification? (Choose one)
1. Did your team correctly identify the specimen? A) We narrowed it down to a few species, but variation in
characters within species made it hard to choose one.
B) No B) The specimen lacked one of the key characteristics we
expected for that species and/or had one normally
found in another species.
C) The specimen was damaged, dirty, immature, or the
wrong part of the shell.
D) The information in the field guide was not organized in a
straightforward way (i.e., no taxonomic key).
E) None, we were awesome and got it right easily.
