1. SEA-HORSE IN SARGASSO WEED. In its frond-like tags of skin and in its colouring this kind of sea-horse is well 

 concealed among the floating seaweed of the so-called Sargasso Sea. 



2. THE LARGE MARINE LAMPREYS (PETROMYZON MARINUS), WHICH MAY BE AS LONG AS ONE'S ARM, 

 SPAWN IN FRESH WATER. Stones and pebbles, gripped in the suctorial mouth, are removed from a selected spot and piled around 

 the circumference, so that the eggs, which are laid within the circle, are not easily washed away. 



3. THE DEEP-SEA PISH CHIASMODON NIGER IS FAMOUS FOR ITS VORACITY. It sometimes manages to swallow 

 a fish larger than itself, which causes an extraordinary protrusion of the stomach. 



4. DEEP-SEA FISHES. Two of them Melanocetus murrayi and Melanocetus indicus are related to the Angler of British 

 coasts, but adapted to life in the great abysses. They are very dark in colour, and delicately built; they possess well-developed lu- 

 minous organs. The third form is called Chauliodus, a predatory animal with large gape and formidable teeth.
