In the future, you might want to let us know what part of the world you are from....it helps when wanting an identification.

Your critter is not a spider, though it looks like one. It's one of the many species of what are commonly called wind scorpions (though not a scorpion, either), sun spider, sun scorpion, etc. They are Arachnids, related to spiders but not spiders.

These animals are active predators and can be considered helpful around your property. They can bite if handled, but they are not venomous.

rhizo_1, a curiosity - is the smaller set of "legs" between the front two pairs for gripping prey? Do you know what they are called? Thanks,

These arachnids have 5 pairs of appendages. The set in the front are really modified mouthparts that they use as pinchers. Compare them to the pedipalps on true spiders. The other 8 legs are just true legs in every sense of the word, though they are of different sizes.

This critter is probably still evolving, as we all are, to be the best he can be. Perhaps in a few jillion years, they'll lose those smallest legs.
