How do snakes take care of their babies

I don't like snakes but I went to a zoo where they were telling something like this and the answer is. That means that the baby snakes develop inside their mother. When they are born they are covered with a thin membrane, kind of like a goopy baggie. The baby uses an egg tooth to rip out of the membrane and wriggle free. Other snakes lay eggs in a safe, warm place like in a hollow log or buried in the ground.

Making sure the equipment is cleaned daily and insuring proper hygiene is kept up with the working staff.
