τῶν μὲν οὖν ὀρνίθων ἔνιοι καὶ σκαρδαμύττουσιν 8 ὑμένι ἐκ τῶν κανθῶν, ταῦτα δὲ τὰ ζῷα οὐ σκαρδαμύττει· σκληροφθαλμότερα γάρ ἐστι τῶν ὀρνίθων. αἴτιον δʼ ὅτι ἐκείνοις χρησιμωτέρα ἡ ὀξυωπία πτηνοῖς οὖσι πρὸς τὸν βίον, τούτοις δʼ ἧττον· τρωγλόδυτα γὰρ πάντα τὰ τοιαῦτά ἐστιν. εἰς δύο δὲ διῃρημένης τῆς κεφαλῆς, τοῦ τε ἄνω μορίσυ καὶ τῆς σιαγόνος τῆς κάτω, ἄνθρωπος μὲν οὖν καὶ τὰ ζῳοτόκα τάν τετραπόδων καὶ ἄνω καὶ κάτω κινοῦσι τὰς σιαγόνας καὶ εἰς τὸ πλάγιον, οἱ δʼ ἰχθύες καὶ ὄρνιθες καὶ τὰ ᾠοτόκα τῶν τετραπόδων εἰς τὸ ἄνω καὶ κάτω μόνον.
