Some of the Scopeloids which live in the ocean depths, 

 notably those of the genus Scopelus, are remarkable for the 

 presence of a series of phosphorescent spots known as 

 .photophores along the body; and. in some species, also on 

 the head ; where they may form large patches on the snout. 



One species known as Bathypterois longipes, in which 

 one of the rays of the pectoral fin on each side is tremen- 

 dously elongated, exists at a depth of over 3 miles.
