Assassin Spider:
These spiders are specially adapted to hunt other spiders...their head being elevated upon a long stalk, with huge mandibles, so that they can attack from an elevated distance. They impale their victim, and hoist them into the air while awaiting them to die..
Mole Cricket:
Adorable little tunneling critters that, for whatever the reason, adore water.
Amusingly enough, they can swim as well as they can dig...and they can fly to top it all off. If you ever come across one of these, put it into water before you release it just to watch the thing swim about at mock 1, then release it onto the ground so you can see it dig at said speed as well.
Whip Spider: (
Not Whip Scorpion, although Whip Scorpions are also called Whip Spiders sometimes.)
Vinegaroon:
These guys spray acid when they're annoyed...but I've read that they make awesome pets.
