Animal Trivia : Snail and slug

When we remove shell from the snail, does it become a slug?






A snail and a slug are a different creature as expected.  
Snail shell is made of lime that was seeping from the body.   
Since the shell is attached to the body, if it is torn off from the body by force, the snail will die. 
The shell is same as a shell of short-necked clam and clam.  
  
 The shell of snail is alive. In the evidence, even if shell is damaged and there is a small hole, it is cured in 2-3 days.
