This has to be someone’s pet haha, this is a “skeleton tarantula”
How big do they get?
Hi. This is one of the trap door/cork lid spiders. Ones we have out west don’t excede 2 CM body length.
Yours looks adult or nearly, so close to full grown.
That sounds about right on this one. Its far from home if they typically live in the west.
