Edmund Selous, The romance of the animal world (1905)
“ And all around, over the great, wide sea, these showers of living gems are leaping in and out of it. It is a most beautiful sight. The body of the fish is of a light, gleaming blue, and the delicate film-like wings, springing from just behind the gills, and extending backwards almost to the tail, set it, as they rapidly quiver, in a soft and silvery haze.It is, of course, the pectoral fins that thus perform the office of wings, and by moving them and steering a course, their owner flies as truly, for the time, as does either a bird or a bat. ”
