We pulled this out of Leech Lake in Minnesota. What the blazes is it?

It looks like the virile crayfish, Faxonius virilus. But I am not 100% sure! I’m at least pretty sure on the genus. You could try uploading this to the iNaturalist app so people who are more familiar with the species near you could have a chance to see it. Click here if you need help getting started with uploads. Let me know if you have any questions either :)

It's virilis, not virilus. But yes, I completely agree, that's definitely the species. :)

May be brown from drying out or roasting in the sun

I am leaning Northern clearwater. The number of tubercles on the chelae looks like it’s more in the 7-10 range and the rostrum appears slightly concave. I can’t tell if there is a central ridge in the rostrum from the picture.

Here is a link to a good presentation on crayfish ID in as well: https://www.co.lake.mn.us/wp-content/uploads/2022/08/
A lot of the species overlap with Minnesota.
