The white morph of the northern Clearwater crayfish (F.propinquus) is the rarest and most endangered native crayfish in Canada. It is threatened by the expansion of the invasive Rusty Crayfish in Lake Simcoe where it is now difficult to find. @thetorontozoo.bsky.social !

For her MSc, lab alumna Jaime Grimm (now a prof of Biology at UVic) conducted a novel trans-Atlantic comparison of the ecological performance of populations of the spinycheek crayfish (Faxonius limosus), in its native & non-native ranges.

This is one reason why I love ❤️#crayfish:
They are tough as nails little survivors.
By the way, this is why you never stock a backyard pond with non-native crayfish. They can walk on ground as long as their gills are damp.
They WILL get out and crayfish are among the worst invasive species.
