Handling of autotomized, thrashing and autotomized, exhausted tails of the lizard Scincella lateralis by mammals and snakes was tested to examine the function of postautotomy tail movement. Tail movement attracted a mammal's attack to the tail, permitting the lizard to escape and increased the time required for a snake to subdue a tail before swallowing it, increasing the lizard's escape time by 40 percent. Lactate concentrations of autotomized tails after movement were compared to those of intact tails after rest in S. lateralis, a species with a high rate of autotomized tail thrashing, and Anolis carolinensis, a species with a low rate of thrashing. Postautotomy movement increased tail lactate concentration in both species, but mean tail lactate concentration in S. lateralis was 60 percent higher than that in A. carolinensis, and a third higher than that reportedfor whole-body lactate content of the very mobile lizard Dipsosaurus dorsalis.
通过测试哺乳动物和蛇对侧纹石龙子自断、剧烈摆动以及自断且疲惫的尾巴的处理方式，来研究自断后尾巴运动的功能。尾巴运动吸引哺乳动物攻击尾巴，使蜥蜴得以逃脱，并且增加了蛇在吞下尾巴之前制服尾巴所需的时间，将蜥蜴的逃脱时间增加了40%。比较了剧烈摆动自断尾巴的侧纹石龙子和摆动频率较低的卡罗来纳安乐蜥在尾巴运动后自断尾巴的乳酸浓度与休息后完整尾巴的乳酸浓度。自断后运动增加了两个物种尾巴的乳酸浓度，但侧纹石龙子尾巴的平均乳酸浓度比卡罗来纳安乐蜥高60%，比活动性很强的背甲龙蜥全身乳酸含量报道值高出三分之一。
