Which part of their body do snakes use to inject venom?

About the explaination & "highly modified saliva", I'd say that's quite the understatement. Like "World War II was a bit unpleasant". As for being a food item, the taste may be OK; but snakes are very "boney" & I doubt worth the trouble.

Zedo, If they were, we would be plagued by rodents in many parts of the world, yours included.

devil snake should be erradicated from the world!

I hate snakes.
