1.44

nakrāḥ śiśumārādayaḥ | kacchapaḥ kūrmaḥ | yāni caivamprakārāṇi kṛkalāsādīni sthalajāni | evaṃrūpāṇyaudakāni jalajāni śaṅkhādīni |

Medhātithi’s commentary (manubhāṣya):
‘Crocodiles’—includes the Porpoise and the rest;—‘Kacchapāḥ’ are the Tortoises;—‘other animals of similar kinds’—i.e., wizards (lizards?) and the like, which are ‘terrestrial,’ born on land, and such others of similar kinds as are ‘aquatic’ born in water; such, for instance, as conches and the rest.—(44)
