Meet the Misfortunate and Okanagan Crayfish

Paperleap podcast ·

2025/11/13

Scientists have identified two new species of crayfish in the Pacific Northwest: the Misfortunate Crayfish (found in Oregon) and the Okanagan Crayfish (found in British Columbia and Washington). Using genomic analysis, they split what was previously considered a single species, the Signal Crayfish, into three distinct lineages. The Misfortunate Crayfish is facing a severe threat from invasive crayfish, making its conservation a high priority, while the Okanagan Crayfish faces a slower but similar
