Hi, welcome to Spider ID. 🙂 This looks like a White-banded Fishing Spider, Dolomedes albineus. Like most spiders they have venom but are not considered to be medically significant. Everyone’s immune system is different though.

I’m looking at the placement of the eyes and patterns on the spider’s back. The Carolina Wolf Spider (Hogna carolinensis) is a Wolf Spider (Lycosidae) in range that can be similarly large, even bigger.

This is a Fishing Spider (Pisauridae, Dolomedes albineus), the ID is above the image. I was just saying you can’t always distinguish between the two by size because you mentioned you thought a Wolf Spider (Lycosidae) would be smaller.

Hi, while I agree with D. albineus, I had them in Florida, up close and personal.
Fishing spiders are very often mistaken with wolf spiders. I have also been up close and personal with carolina wolf spiders, and few of those, significantly larger than white banded fishing spiders or dark fishing spiders. The largest I have seen is the raft spider/giant swamp spider, the Dolomedes okifenokensis, estimated 6 inches across the legs. Largest wolf spider, 4 inch legspan,and about the largest white banded, just over 3 inches. Intimidating, but all gentle giants.
