Myriapoda
Myriapods can have anywhere from fewer than ten to nearly 200 pairs of appendages; they range in size from nearly microscopic to 30 cm in length. Most myriapods live in humid environments, and can be found in soils, in leaf litters, or under stones and wood. Many species possess repugnatorial glands, specialized glands that secrete foul-tasing compounds and thus function in defense.
