Document Summary
For each posture type, name the limb elements (hind limb) that touch the ground. Also, name one mammal that is representative of each posture type (provide either common or scientific name). Examples include elephants and hippopotamuses: plantigrade- sole stepping ; place the full length of their foot, including tarsals, metatarsals, and phalanges, on the ground during each stride. Examples include humans, raccoons, and bears and armadillos: digitigrade-walk with most of the length of their digits (phalanges of foot), but not the soles of their feet, in contact with the ground. This increases leg length to increase stride length tarsals and metatarsals do not touch ground. ), walk on hooves with only tip of 3rd digit touching the ground to increase leg length so can run longer and faster. Stride rate and stride length: list three major advantages of large body size in mammals (i gave you four in class).
