Snails are
not known for their quick thinking
but can make complex decisions using just two brain cells , scientists have learned. One cell tells the mollusc if it is hungry or not while the other lets it know when food is present.
Do slugs have feelings?
“It's one of those things that drives you to avoid those [painful] things in the future,” he said. But animals with simple nervous systems, like lobsters, snails and worms, do not have the ability to process emotional information and therefore
