''Bathylychnops exilis'', the Javelin spookfish, is a species of barreleye found in the northern Pacific and in the eastern Atlantic Ocean near the Azores where it is found at depths of around . This species grows to a length of SL. The species is notable for unusual protuberances that grow from its eyes, which each have "a well developed lens"〔Pearcy WG, Meyer SL, Munk O (1965). A 'Four-Eyed' Fish from the Deep-Sea: ''Bathylychnops exilis'' Cohen, 1958. ''Nature'' 207, 1260-1262.〕 and a retina, and which have led to the species being called a "four-eyed" fish.〔 It has been suggested that the purpose of these extra eyes is detection of threats from below, since these eyes point downwards.〔Dawkins R (2009). ''The Greatest Show on Earth: The Evidence for Evolution''. London: Bantam Press.〕 ==References==
