Abstract

COSTA, Fabiana R et al. Kinematic description of the vertical climbing of Dasypus novemcinctus (Xenarthra, Dasypodidae): the first report of this ability in armadillos. Mastozool. neotrop. [online]. 2017, vol.24, n.2, pp.451-456. ISSN 0327-9383.

Armadillos are well-known quadrupeds whose digging abilities classify them differently into many fossorial categories. This is the first time a kinematic description is provided on the vertical climbing sequences performed by these animals, more specifically by the nine-banded armadillo Dasypus novemcinctus. After an opportunistic observation of climbing behavior, video recording sessions were setup to document wire mesh climbing. The individuals climbed up to its top showing four distinct ways of vertical progression, such as lat­eral and diagonal-sequences as well as few styles that resemble the asymmetrical motions used by quadrupeds on land. Sharp claws were used as strategic points of attachment on a substrate, and tails provided additional support during vertical progression. Thus, the locomotory repertoire of armadillos is far more diverse than previously considered.
