OTHER CREATURES WHICH LIVE IN THE 



SEA. 



ESIDES the mollusks, there are a great 

 number of other creatures in 

 the sea which claim our atten- 

 tion. As we go down to the 

 beach on a bright morning, 

 perhaps the first living things which we notice 

 are the birds. Sea-birds have a look of their own, 

 and you would hardly mistake them for land-birds, 

 if you were to meet them many miles inland. 



While our land-birds are mostly fitted for short 

 flights, as from tree to tree, the sea-birds go wing- 

 ing along over miles of waves, and perhaps alight 

 at last on some bare rock, in the midst of a flock of 

 their companions. Land- 

 birds sing, at least many of 

 them do, but sea-birds are 

 silent, or utter a few harsh 

 cries. Besides this, they are 

 all fitted for swimming or 

 wading, and many of them 

 for diving as well.
