I don't know know the Shasta Crayfish well, but it is apparently critically endangered.
A new mural by Louis Masai, The Art Of Beeing, is now on the back of the G2 Gallery, and features this fish and a bee, and now I'm glad to know about it. The Shasta Crayfish is not the only thing critically endangered these days. We all are. Please watch the climate change documentary Before The Flood (from Leo DiCaprio) and realize that it doesn't matter at all who political leaders are if there is no human life left to lead. It's seriously coming to that.
Let's focus on what is truly Important. Life on this planet.
