The fish alepo does not live out of water.
This bird converts iron into nourishment, and hatches its eggs by its gaze;--Armies under commanders.
The swan is white without any spot, and it sings sweetly as it dies, its life ending with that song.
This bird, by drinking saltwater purges itself of distempers. If the male finds his mate unfaithful, he abandons her; and when it grows old its young ones brood over it, and feed it till it dies.
