I love snakes and people make me mad calling legless lizards snakes even though they look alike. 
Wow!  Why do you like snakes?
I love the elongated, legless carnivores because they are actually reptiles of suborder Serpentes!  So cool. 
What is a legless lizard?  I've never heard of such a thing!
They are like snakes but have eyelids, external ears which snakes don't have. 
Where are they located?
Well snakes are found on every continent except Antarctica and on most smaller land masses but not Ireland, Iceland, Greenland, Hawaiian aarchipelago and New Zealand and small Atlantic and Pacific islands. 
Why are there no snakes in those places?
Not sure but snakes have skulls and joints so they can swallow prey that are much larger than their heads with their mobile jaws!
You are quite the snake expert!  Do you own any snakes?
