Resumen
The superorder Xenarthra (former Edentata) is grouped into two orders, Cingulata (armadillos) and Pilosa (anteaters and sloths). These are special mammals
that show unique traits: (1) the existence of secondary articulations called xenarthrales located between the lumbar vertebrae and the spinal column; (2) the
presence of fused pelvic bones; and (3) very low metabolic rate and variable body temperatures, which allow xenarthrans to conserve energy. They are also
highly specialized, but diverse in terms of dietary needs. Xenarthrans include strict folivores such as the three-toed sloth (Bradypodidae), omnivore-generalists
such as the two-toed sloth (Choloepus spp.), specialized carnivores such as the giant anteater (Mymecophaga tridactyla), and the tamanduas (Tamandua
tetradactyla, T. mexicana). Armadillos vary in their diet, with certain species feeding mainly on ants and termites but others, such as the common Dasypus
novemcinctus, are omnivorous.
