Hibernation is convenient when you live in a shell
Wiggling antennae poke out from under coiled shell of the second-most prolific species on earth, the gastropodal snail. On land and in oceans and freshwater, 43,000 snail species live. North America has 500 land species, which brings them, usually stealthily, to all our gardens.
But you won’t see them this time of year, for many snails hibernate from October until April. Hibernation is convenient for snails as they carry their beds on their backs. In dry areas, snails can hibernate for years.
