General methodology for determining growth rate of elephant toenails. (A) An initial marking was made near the cuticle of the elephant toenail at the start of the study date (indicated in red). (B) Every 2 weeks, the distance the mark travelled from the cuticle was measured (indicated by the red arrow). Growth rate was determined by dividing the distance travelled by the time interval between the initial mark and the new position. Image credit: Chase LaDue.
