American Crayfish Atlas

The American Crayfish Atlas is a collaborative project developed in the lab of Dr. Christopher Taylor at the Illinois Natural History Survey, Prairie Research Institute. Dr. Taylor researches the conservation and systematics of North American crayfishes and serves as the curator of fish and crustaceans at INHS. This website is designed and maintained by Ms. Caitlin Bloomer. She is a graduate research assistant in the Taylor lab and currently studies burrowing crayfish conservation.

Crayfish locations have been sourced from peer-reviewed literature and online databases to provide high quality distributional information. Crayfish locations are mapped across the United States. The map can be used to explore and compare individual species distributions state-wide or nationally. ‘Species by State’ provides the species names and number of locations within each state.
