This is a shot of a centipede protecting its young by curling up around them. I don't know about you, but I would definitely feel safe with those dagger legs wrapped around me. This is the exact same reason why I always sleep with an unsheathed ninja sword at night. "To protect your young?" Yes. "But I thought you didn't have any kids." I do, they're just still in my nuts.
Keep going for a couple videos of centipedes protecting their young in case you're really determined to have nightmares tonight (PROTIP: Eat seafood or a spicy sausage right before bed).
Thanks to Eric A, who is a firm believer in letting your children fend for themselves gladiator style.
