An enormously developed giant cheliped with the other small one characterizes the adult male fiddler crab. Some experiments with artificial severances of cheliped indicate that such a handedness in the cheliped size is maintained even after the regeneration of severed cheliped. Other experimental researches give some results about an unknown physiological system which controls the emergence and the regeneration of the handedness in the cheliped size. In this paper, with two hypothesized factors relevant to the regeneration of a severed cheliped, we propose a simple mathematical model to describe the experimental result about the cheliped regeneration with a handedness after the cheliped severance for the fiddler crab. Our model gives a suggestion about an underlying system for the cheliped regeneration in the fiddler crab or some other crustacean species.
成年雄性招潮蟹的特征是一只螯极度发达成为巨螯，而另一只则很小。一些关于螯足人为切断的实验表明，即使切断的螯足再生后，螯足大小的这种不对称性仍会保持。其他实验研究给出了一些关于控制螯足大小不对称性出现和再生的未知生理系统的结果。在本文中，基于与切断螯足再生相关的两个假设因素，我们提出了一个简单的数学模型，以描述招潮蟹螯足切断后具有不对称性的螯足再生的实验结果。我们的模型为招潮蟹或其他一些甲壳类动物的螯足再生潜在系统提供了一个见解。
