Deep-sea fishes, as a rule, have either very large eyes or no eyes at all. The large eyes are fitted to make the most of the littlo light that is present at great depths, and this is amplified by tho phosphorescence of certain deep-water denizens themselves. A bunch of polyps oii a flexible stem was brought up from a depth of 2175 fathoms, between Madeira and the Spanish coast. As it came to the surface it gave out a brilliant phosphorescence, as . did many alii eel forms dredged in deep water. No doubt these creatures, like their congeners m shallow waters, emit light in the deep sea; and the deep-sea animals with eyes probably congregate round them or grope their way in the gloom from one collection to another as they lie scattered ovtw *he bottom.
