Crustaceans, insects and to a lesser degree arachnids have been employed in regeneration studies. Amputation and ligation of the legs was used to determine occurring in a Black Widow spider complied with the developmental gradient model of regeneration. The occurrence of autotomy in this species was also documented. Amputation indicated the most proximal point from which regeneration of the leg could occur was the femoral mid-point. Amputation proximal to that area did not result in leg regeneration. Autotomy following amputation was not observed. Ligation of the legs resulted in autotomy when applied at and proximal to the mid-point of the tibia, increasing in frequency as more proximal segments were ligated. Autotomy always occurred at the trochanter-coxa joint. Autotomized legs did not regenerate. The regeneration observed complied with the developmental gradient model.
甲壳类动物、昆虫以及在较小程度上的蛛形纲动物已被用于再生研究。对腿部进行截肢和结扎，以确定黑寡妇蜘蛛身上发生的情况是否符合再生的发育梯度模型。该物种自切现象的发生也有记录。截肢表明腿部能够再生的最近端点是股骨中点。在该区域近端进行截肢不会导致腿部再生。截肢后未观察到自切现象。当在胫节中点及近端进行结扎时，腿部会发生自切，随着结扎的节段越靠近近端，自切频率增加。自切总是发生在转节 - 基节关节处。自切的腿部不会再生。观察到的再生符合发育梯度模型。
