Those are actually pretty low on the myriapod totem pole, in terms of leg number. Scolopendromorphs have forty-two legs. Some of the soil centipedes and millipedes have many, many more than that. I think the little suckers we find under most logs in temperate climates of North America have thirty legs.. scutigeromorps and lithobiomorphs. They are little. While they are, technically, poisonous, they haven't the venom, nor the biting power, to ever harm a human. Scutigera (house centipede) isn't even that aggressive if it was able to inflict a wound.
They are the only centipedes with compound eyes.
Wow... I never planned on knowing all this.
