Spiders

Lets not exaggerate.

I'd like to point out that the show that clip is from, Walking with Monsters, is one of the best, most fascinating productions in the history of television.

Not technically a centipede.

Given that it's part of an extinct family, I'm willing to accept an approximation.  ALthough it more resembles a millipede.
