This is a solifugae or Camel Spider, which aren’t spiders but are in the arachnid class.
Is this photo from a website? For our record keeping of locations where spiders are found it is helpful to know if you found this spider in Colorado. Please let us know 🙂
I have found these in my tub on occasion. Location: Ellicott, CO
Sunspider, sunscorpion also windspider. Relative of the Camel Spider. Harmless. Great for taking care of other pest insects. Good info on Britanicca.com
