Three toed sloth
Bradypus variegatus

Field Notes
Description:
Three-toed sloths have no incisor or canine teeth, just a set of peg-shaped cheek teeth that are not clearly divided into premolars and molars, and lack homology with those teeth in other mammals, thus are referred to as molariforms. The molariform dentition in three-toed sloths is simple and can be characterized as dental formula of:
5
4-5
Three-toed sloths are unusual amongst the mammals in possessing as many as nine cervical vertebrae, which may be due to mutations in the homeotic genes.] All other mammals have seven cervical vertebrae, other than the two-toed sloth and the manatee, which have only six.
