Une grenouille au pays des ours blancs

Ticks have eight legs and are in the same class as spiders but they're in a different superorder. For comparison, egg laying monotremes (like the platypus) and hairy critters that don't lay eggs (kangaroos, people) are all in class Mammalia but they're in two different subclasses.

Ergo, ticks are like really creepy spiders. Creepy and crawly.
