四分律行事鈔資持記 1.797

畜生中。同取變化，故亦前科。律下，引證。即《善見》龍王厭身，化為外道出家受戒已，因睡現本形；佛即制斷，如文所引。龍為緣起，餘畜皆然。

Under 'animals': Likewise, taking on a transformed state applies here, so it also follows the previous heading. The text from 'The Vinaya' down cites evidence: That is, in the Samantapāsādikā, a dragon king, disgusted with its body, transformed into an outsider, went forth, and received the precepts; afterward, while asleep, it manifested its original form, whereupon the Buddha prohibited it, as cited in the text. The dragon serves as the origin, and all other animals are the same.
