120 VERTEBRATES: FISHES. 



lantic. The Remora has a flattened head, so constructed 

 that it is able to attach itself by this part to other 

 marine animals. It is a foot or more in length. Eels 

 have a long, round body, which is covered with a thick, 

 soft skin. They live in both fresh and salt waters, and 

 keep near the bottom, often lying concealed in the mud. 



TUFT-GILLED FISHES. 



These fishes have their gills in tufts, and are known 

 as Pipe-Fishes and Sea-Horses, on account of their sin- 

 gular forms. Pipe-Fishes have a very long and slender 

 body covered with hard plates, and long snout with the 

 mouth at the end. They live in the warm seas. After 

 the eggs are laid, the male takes them in a sort of sack 

 and carries them about with him till they are hatched. 

 Sea-Horses have a short body, which is covered with 

 spiny plates, a tail adapted for grasping small objects, 

 and the head and neck have some resemblance to those 

 of a horse. They are from three to six inches long, 

 and live in the sea. 



PUFFERS, TRUNK-FISHES, &c., OR PLECTOGNATHS. 



Puffers have the body covered with spines, and can 

 swell themselves like a balloon by swallowing air. The 

 Common Puffer lives in the Atlantic Ocean, and is about 

 a foot long. 



The Sun-Fish, of the Atlantic, grows to the length 

 of four feet, and weighs five hundred pounds. 



The Trunk-Fish has the head and body covered with 

 bony plates, so firmly attached to each other that they 

 form a shield, and the mouth, tail, and fins are the 

 only movable parts. Two or three kinds are found on 

 the Atlantic coast of the United States.
