龜毛（愧逵反字統曰龜水介蟲也外骨而肉內也從它龜頭與它頭同天地之性也廣[一/(尸@肉)]無雄龜鼈之類以它為雄左象其足右象背文頭尾象形）。

Guimao 龜毛 (pronounced with the fanqie 愧逵. The Zitong says: "The tortoise is an aquatic shelled creature; its bones are outside and its flesh is inside. It is formed with 它 [snake]; the head of a tortoise is the same as the head of a snake, being of heaven-and-earth's nature. Generally among shelled creatures there are no males, and creatures like tortoises and turtles take snakes as their mates. The left side depicts its legs, the right side depicts the pattern on its shell, and the head and tail are pictographic").
