Note 2466 — BOOK IX. THE NATURAL HISTORY OF FISHES.
John Bostock translation
Aristotle, Hist. Anim. B. viii. c. 75, says the same, and likewise that they feed mostly at night. The reason for their not floating when dead, he says, is their peculiar conformation; the belly being so remarkably small that the water cannot find an entrance; added to which they have no fat upon them.
