Introduction to the Myriapoda
... All myriapods are terrestrial forms. Like insects and other uniramian arthropods, myriapods have appendages with only one branch, or ramus. 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 ...

Anti-predator adaptation
Anti-predator adaptations are mechanisms developed through evolution that assist prey organisms in their constant struggle against predators. Throughout the animal kingdom, adaptations have evolved for every stage of this struggle.The first line of defence consists in avoiding detection, through mechanisms such as camouflage, living underground, or nocturnality. Alternatively, prey animals may ward off attack, whether by advertising the presence of strong defences in aposematism, by mimicking animals which do possess such defences, by startling the attacker, by signalling to the predator that pursuit is not worthwhile, by distraction, by using defensive structures such as spines, and by living in a group. Members of groups are at reduced risk of predation, despite the increased conspicuousness of a group, through improved vigilance, predator confusion, and the likelihood that the predator will attack some other individual.Some prey species are capable of fighting back against predators, whether with chemicals, through communal defence, or by ejecting noxious materials. Finally, some species are able to escape even when caught by sacrificing certain body parts: crabs can shed a claw, while lizards can shed their tails, often distracting predators long enough to permit the prey to escape.
