§173.1Fr. 173
Θ. ἐν τῷ περὶ τῶν μεταβαλλόντων τὰς χρόας τὸν πολύποδα φησὶ τοῖς πετρώδεσι μάλιστα τόποις συνεξομοιοῦσθαι· τοῦτο ποιοῦνται φόβῳ καὶ φυλακῆς χάἐυ ριν.
Theophrastus, in his *On Those Which Change Their Colors*, says that the octopus assimilates itself especially to rocky places; they do this out of fear and for the sake of self-defense.
Ἐν δὲ τῷ περὶ τῶν ἐν τῷ ξηρῷ διαμενόντων ζώων οὐ δέχεσθαί φησι τοὺς πολύποδας τὴν θάλατταν·
And in his *On Animals That Remain on Dry Land*, he says that octopuses do not tolerate the sea.
ἐν δὲ τῷ περὶ κατὰ τόπον διαφορῶν ὁ Θ. πολύποδας οὐ γίνεσθαί φησι περὶ Ἑλλήσποντον· ψυχρὰ γὰρ ἡ θάλασσα αὕτη καὶ ἧττον ἁλμυρά· ταῦτα δʼ ἀμφότερα πολέμια πολύποδι.
Furthermore, in his *On Differences according to Place*, Theophrastus says that octopuses do not occur around the Hellespont; for this sea is cold and less salty, and both of these are hostile to the octopus.
