Aristotle [ca. 350 BCE] (De animalibus, Book 8, 20.14): In the river Hypanis in the Cimmerian Bosphorus, about the summer solstice, capsules larger than grape-seed are floated down the river: when these are ruptured, a four-footed, winged creature makes its escape, which lives and flies about till the evening. As the sun descends, it becomes emaciated, and is dead by sunset, having lived but one day; for which cause it is called ephenierum. - [Cresswell translation, 1887]

Thomas of Cantimpré [circa 1200-1272 CE] (Liber de natura rerum, Fish 7.30): Day-fish (dies piscis) is a fish of the sea, as Aristotle says, which after its completion does not live but for one day. And therefore it is called a "day" in which there is a perfect sunrise and a sudden sunset. And in this very wonderful nature, that an animal created for life forces life to end so suddenly. Here the diligence of the Creator is noted: for this animal has two wings and two feet, and lacks blood. But what should it do in such a brief service? It is truly a sufficient reason that God is said to be wonderful in his creatures. - [Badke translation/paraphrase]

Bartholomaeus Anglicus [13th century CE] (Liber de proprietatibus rerum, Book13.26.): Also in li. Jorath de Animalibus it is said, that a Fish yt is called Effimeron is bred without generation betwéene male and female: And when he hath lived thrée houres of a day, then he dieth. - [Batman]
