Jumping Spiders
Ah yes, I love them little guys. They're beautifully colored, and their fur is stripped and spotted, often with iridescent blue and green scales over their fangs. I especially like the way they turn and face you and gesture with their front legs to try and scare you off (or maybe they have sensors on their feet?). They really are fearless. And they have those cute little turret heads with eyes facing every which way.
I guess if they were the size of hamsters they'd freak me out, but at under an inch long I think they're adorable.
