Text Translation:
Here begins the account of fish. Fish, pisces, get their name, like cattle, pecus, from the word for grazing, namely, pascere. They are called reptiles because, when they swim, they have the appearance and manner of crawling. Although they can dive deep, nevertheless they crawl as they swim. On this subject David says: ‘So is this great and wide sea, wherein are things creeping innumerable’ (Psalms, 104: 25)
