Moved from Spiders.

Wolf Spider?
A beauty! I'm having a hard time seeing the detail, but the eye arrangement looks like wolf to me.

a Hogna helluo?

It looks just like it. You can see it on this site: CLICK HERE

H. helluo
It does appear to be one. That's a very impressive specimen.

It was
a little bigger then the young slimey salamander next to it. A am about to add another picture.

Misidentified... This is Hogna aspersa
This is an adult Hogna aspersa female.

Hogna aspersa can be distinguished from helluo by the tiger stripes on the base of the legs, hence it's common name: The Tiger Wolf Spider. Females and males are very different looking. Juveniles are also very different, being brownish yellow with a slightly purplish sheen. Most adult female aspersas tend to be a jet black color, wheras Helluo is more of a dusky brown with lighter legs. I'll be posting pictures soon...

According to Penn State Entomology, here's a description:

"Hogna aspersa females are 18 to 25 millimeters in length, and the males are 16 to 18 millimeters. They are similar to H. carolinensis in body color but have a distinct narrow line of yellow hairs on the carapace in the vicinity of the eyes. The legs are banded with a lighter brown color at the joints. The males are much lighter in color than the females, and only their third and fourth pairs of legs are banded with a lighter color."
