Midrasch zu Ijow 29:18

(Gen. 8, 19) After their families. R. Jochanan said: "Infer from this that each family was placed separately." R. Chana b. Bizna said: "Eliezer, the servant of Abraham, questioned Shem the senior (son of Noah). 'As all the animals were placed separately, where was your family placed?' And he answered: 'We had great trouble in the ark to feed all the animals. The creature whose habit it is to eat in the daytime we had to feed by day, and those whose habit it is to eat in the night, we had to feed by night. A chamoleon, my father did not know what its food was. It happened one day that he cut a pomegranate and a worm fell out of it, and the chamoleon consumed it, and from that time he prepared its food from bran that had become wormy. The lion's fever fed its vital energies, as Rab said: Not less than six and not more than twelve days one can live in fever without taking any food. The phoenix my father found that it slept in a corner of the ark, and to his question, 'Dost thou need any food,' it answered, 'I saw thou wert very busy, and I thought I would not trouble thee.' And he blessed her that it should never die, and concerning it says the passage (Job 29, 18) As the chaul (phoenix) shall I have many days'."
