Water snails have heavy shells that help keep them on the bottom.
Yes,they will die in water because snails will die under water so yes.
because land snails normally stay on land and pond snails stay in the water
Aquatic snails (as opposed to land snails) and fish live entirely in water - either fresh or salt, depending on their nature.
Yes they do breathe air from water they is how they stay alive they can live for a month under water you also may see a pond snail upside down with their bottoms out of the water they are breathing!
You find Them under Water =]
Pouch snails eat things under water such as algae and underwater plants.
Over time the snails have evolved. this evolution developed structures of the snails body so that it could live under water i.e. a siphon to obtain air without having to leave the safety of water, gills, water vascular system for circulation of oxygen.
Snails and slugs have lungs, so they can breathe.
snails live space and fart underwater that is why you see bubbles rise from them :D
Some species can survive years out of water ( in mud/clay) others not so long.
Bladder snails cannot survive outside of water for extended periods of time. They need a moist environment to breathe and stay alive.
water snails but not regular snails
