Looks like a wolf spider zoomed in a LOT. They carry hundreds of babies on their back. We get them all the time here in Florida. When you go to squish them, the babies run everywhere.......but the babies are about the size of a pinhead.

they are actually good to have around the exterminator tells us. They don't bite, and they eat bad insects.
