The humble garden snail is one of the most common sights of the British countryside but how much do you actually know about them? Walk - or slide - this way. Old heads. A snail's lifespan is dependant on what exact species they are and what habitat they live in. Some only live for 5 years but can if lucky enough can live to as long as 25. Best foot forward. While it may not look like it snails slide around on a single foot. The one long muscle acts just like a human extremity and helps them grip and push themselves along the ground. Are they poisonous?
