Outside my experience: possible Rusty Crayfish (Orconectes rusticus), literally 1000's of them on the beach during a very windy day with large waves, Lake Simcoe, McRae Point Provincial Park, Orillia, ON, Aug 5/17
Nestled between two Mudpuppies in a bed of Leptodyctium riparium.
With the downward pressure of my boot, I was able to propel the crayfish out of its semi-flooded chimney.
Note (2022-02-16): The most significant threat to this occurrence would be European Common Reed (Phragmites australis ssp. australis). A stand exists within ~15 m to this observation.
If this occurrence is situated within suitable habitat, there is a myriad of suitable habitat locally for this taxon.
This was an incidental observation. This taxon was not known to exist in this area until this observation was confirmed.
Not sure if it can be determined it's a Short-tailed or Long-tailed from this photo
Three at once.
Was at least six individual skunk visitors that night.
