They are differnet colours
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.
About 5-10 years old.
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.
The only way to tell if a snail is dead is to sniff the snail, if it gives off a strong, odorous scent, it is most likely dead.
