Spiders are the most common type of arachnid found around the world, with roughly 3400 species found in North America alone with a fossil record that dates back a staggering 400 million years! All true spiders produce silk, and most species have venom that both kills and liquifies their prey.

Scorpions are a fascinating group of arachnids that are very easy to identify: two claws in the front and a venomous stinger held up from behind and above its body. Modern day scorpions have evolved from massive eight-foot marine ancestors, and have a fossil record that stretches back 430 million years. They are now found all over the world except Antarctica.

Also called camel spiders, wind scorpions, or sun spiders - these secretive and seemingly ferocious invertebrates are not commonly seen, and are distinguished by their two large chelicerae (think "mouth-claws") that rip their often still-living prey to pieces as it slurps the liquids into its mouth.
