对一头体重约750公斤的幼年白色犀牛的腿长骨的长度和横截面的几何特性进行了测量。这些都被认为是与数据的电影白色犀牛小跑和疾驰。与其他大型哺乳动物相比，奔跑时骨骼中产生的应力相当低，这表明犀牛骨骼可能具有异常高的安全系数。大象的腿长，相对直（其骨骼承受更高的压力），与其他重力门哺乳动物的腿短，不太直形成对比。
Measurements have been made, of lengths and of geometric properties of cross-sections, of the long bones of the legs of a young white rhinoceros of about 750 kg body mass. These are considered in conjunction with data from film of white rhinoceros trotting and galloping. The stresses developed in the bones in running are rather low, in comparison with other large mammals, suggesting that rhinoceros skeletons may be built to unusually high factors of safety. The long, relatively straight legs of elephants (whose bones experience higher stresses) are contrasted with the shorter, less straight legs of the other graviportal mammals.
