TUNICATES (Sea Squirts) 



Tunicates are soft— bodied, more or less leath- 

 ery animals of various irregular shapes, often 

 with a translucent covering (figs. 10 and ll) , 

 Each individual has two openings, one used as the 

 intake and the other as the discharge for the sea 

 water from which they sift their food, but as 

 some kinds are colonial, a single mass may have 

 more than one pair of holes. From their habit of 

 expelling sea water, sometimes from both openings 

 at once, these animals have also received the 

 name of sea squirts.
