Picture guide to crayfish in Oregon; Crayfish information from SeaGrant; and ODFW Red Swamp Crayfish fact sheet.

Location

This was on a gravel road at the Finley National Wildlife Refuge south of Corvallis. I wasn't sure what it was; it looked like a crawfish but didn't have claws. I've discovered they can lose them and grow them back.
