DEEP-SEA FISHES .(drawn to various scales) 



The fishes of the deep sea are highly carnivorous forms, often 

 provided with formidable teeth. The eyes are either very large or 

 else greatly reduced. Luminous organs are often present. Many ot 

 these fishes are of bizarre appearance, as may be gathered from 

 the plate, which represents eight species, as follows : 



1. Sternoptyx diaphana: small and translucent, with rounded 



luminous organs on the sides of head, body, and tail. 



2. Cyema atrum : a small deep-sea eel, with reduced eyes. 



3. Malacosteus Indicus: very large eyes, two luminous organs 



on the side ot the head, and enormous mouth. 



4. Idiacanthus ferox : a greatly attenuated form, with numer- 



ous small rounded luminous organs on the side of the 

 body. 



5. Nemichthys ingens : a greatly elongated deep-sea eel, with 



large eyes, and jaws drawn out into a slender beak. 



6. Saccopharynx ampullaceus : a large deep-sea conger-eel, 



which has succeeded in swallowing a fish much bigger 

 than itself. 



7. Bathypterois longicauda : a deep-sea fish with reduced eyes, 



and much elongated fin-rays serving as feelers. 



8. Macrurus crassiceps : a species of a widely distributed deep- 



sea family related to that including the cod, &c. Eyes 

 extremely large, and mouth on the under side of the head.
