Now see, this animal mentioned must be because of it's purpose, always with it's head in the atmospheric air, therefore it needs just this trunk-like foot; for at the time of night or winter it stands on it's extended foot, reaching out above the surface of the snow, lures a species of night bird, which are not unlike the small earth-bats, into it's vicinity, catches them there, or rather lets them fly into it's wide-open mouth, which breathes pleasant warmth, and then consumes them at once. See, this is the one purpose of this long foot. – The Moon, Chapter 3, Paragraph 7
