Relative warps (RW) analysis results of the interspecific dataset. The plot shows that the two genera Choloepus and Bradypus occupy distinct regions of the morphospace. B. variegatus and B. tridactylus cluster together, whereas the two specimens, C. didactylus do so as well but show less overlap. In all analyzed sloths, the cervical vertebra 2 is very distinct in its morphology and is separate from the postaxial vertebrae
