蚯蚓具较强的再生能力早已为实验所证实。在中等师范学校《生物学》教材中明确提到,蚯蚓的身体受到损伤或者切会了一小部分,过了一段时间后,所损失的部分能够重新生长出来,且蚯蚓身体后端的再生能力强,损伤部分容易重新生成;前端的再生能力较弱, The strong regeneration ability of cooking utensils has already been confirmed by experiments. In the “Biology” textbook of secondary normal schools, it was explicitly mentioned that the body of the skeleton was damaged or cut a small part. After a period of time, the lost part can be re-grown and the ability to reproduce at the back of the body is strong. The damage part is easy to regenerate; the front end has a weak regeneration capability.
