digitigrade /ˈdɪdʒɪtɪˌɡreɪd /adjective Zoology(Of a mammal) walking on its toes and not touching the ground with its heels, as a dog, cat, or rodent. Compare with plantigrade.Because of their digitigrade stance, walking down stairs was difficult for them to do rapidly....- Bear in mind that this rule applies even in the case of extreme digitigrade organisms in which a ‘ventral’ or ‘plantar’ view of the ankle in a natural life position requires one to look down on the tarsals and see the top side of the foot.
- Thus, by the early Late Triassic sauropods had relatively small forefeet that were held in a nearly vertical, digitigrade posture in which the five weight-bearing digits were arranged in a gentle arch.
Origin Mid 19th century: from Latin digitus 'finger, toe' + -gradus '-walking'. |
