FISHES

The useful purpose of such light organs to their owners 

 is apparent. Less obvious, however, is the advantage to 

 be gained by luminous teeth as seen in certain deep-sea 

 Anglers, whose enormous fangs advertise themselves to 

 intended victims by a bluish radiance. 



Deep-Sea Fishes 



One luminous fish (Photoblepbrori), common around the 

 Island of Banda in the Pacific Ocean, is put to commercial 

 use by the local fishermen, who cut out the enormous light 

 organs from either side of the head and use them as bait. 

 The light organs continue to function long after removal 

 from their rightful owner and tempt other fishes to seize 

 the hook which they are employed to conceal.
