Snails stink horridly when they die. If you have the stomach, you can pick he/she up and get a little whiff. Trust me, you'll know then if he/she is dead or not.
If I could do that, I would be very famous, and very rich.
Snails that do not move for a day are definitely not well. An easy way to tell is to pick it up and smell it, and if it smells rotten, then its dead or dieing. Don't inhale too deeply, as rotting snail smell is one of the most disgusting smells you can smell.
you can tell by it shell
They are differnet colours
Why? i dont think snails get unhappy unless they are hungry or dying.
Many snails have different length and sizes so you can't tell what is the length of a snail if you didn't tell what snail it is.

you can tell by how many stripes they have on there shell
The conus or cone snail is a sea snail. Sea snails live in the ocean and cannot survive out of water like garden snails. These snails are predators and are equipped with painful poisonous stings. There are reports of people dying after being attacked, but it usually only causes severe pain.
you can't tell because snails have many predaters so if you have a pet snail try to keep it away from bugs,mice,cockroachs,spider, and etc
you cant really because snails are hermaphrodites; they have both male and female organs.:)
i don't know but i have a snail i don't know if it is healthily if it dies i will cry I Love My Pet Snails.
