Crawfish migration! - Procambarus clarkii - male - female

Crawfish migration! - Procambarus clarkii - Male Female
Marin County, California, USA
October 25, 2010
Size: 10-15 cm body length
I walked down to a creek a few days ago and noticed that there were hundreds of crawfish migrating upstream. The creek was newly-formed after a few day's worth of rainfall. Has anyone seen anything like this before? Were they seeking a new food source or something?

cool!
That's pretty interesting. These guys will bury in the mud, maybe they were just waiting for water to return to the channel?
