I don't think the resemblance is that close, but the part of the eye that has color and sometimes some visible internal structure to it, lines and striations and so forth, is called the iris. Inside the iris is the pupil, which is black, and outside the iris is the white.
In a part of the inner ear called the cochlea (snail-like).
No the shell is apart of its skeleton, like it's spine and ribs A turtles shell is built into bone structure. Parts of the backbone and the ribs, among other bones, make up the inner structure of the shell. This means that it cannot get out of its shell, as the shell is not separate from the body.
Corona

Cell wall
The oldest part of a snail's shell is the center of the coil. When the snail grows, it grows outward
Cochlea
Yes! The shell of a snail is just like our spine. Its true- do not try and remove at anything- the snail would die a slow and painful death!
snail shells can be brown or gray, sometimes speckled. i heard they can be green too, but i have never seen it. the shell is part of the snail, a hardened skin, so it usually looks somewhat like the snail. they don't have to look spinny or spiraly, but sometimes are. it may have something to do with what they eat. . . maybe.
The cochlea and the stirrups are all part of the inner ear system. The cochlea looks like a twisting snail's shell, and the stirrups look like stirrups on a horse saddle.
It depend on what type of Snail it is because most snail produce their own shells, so the type of snail matters because some snails grow shells quicker than others and have a chance of surviving than the ones that can't grow their shell as quick.
No; the shell grows as part of the snail.
Note: I copied this answer directly from: http://rochester.kidsoutandabout.com/main-columns/nature/snailshells.html Snails are hatched from eggs. When they hatch, they eat most of the shell, but a small part of it stays with them and that is the beginning of their shell. As the snail grows, so does its shell -- in a spiral shape. New shell is added at the opening of the shell. In the center of the spiral is the part of the shell that the snail began life with. The shell is made from several layers. The thin outer layer is made from an organic substance known as conchiolin. The thicker layer underneath is formed from three layers of crystalline calcium carbonate, similar to the chicken egg of which you may be more familiar. The color of the shell depends on the types of food the snail is eating and also the type of snail.
Snails are born with their shell. As the snail grows, so does its shell -- in a spiral shape. New shell is added at the opening of the shell by the mantle.

The only way I know of is to strip down the tank, sterilise everything and replace everything that can not be sterilised. A method of keeping snails under control is to have Clown Loaches or Puffer fish in the tank. They will seek out and eat the snails.
The simple answer: In the inner ear the cochlea (the roundish wound up thing that looks a little like a snail shell to me), picks up vibrations from the eardrum (AKA Tympanic membrane) which are then converted to nerve impulses, which are received by the brain as sound.
What a thoughtful question! Snails are hatched from eggs. When they hatch, they eat most of the shell, but a small part of it stays with them and that is the beginning of their shell. As the snail grows, so does its shell -- in a spiral shape. New shell is added at the opening of the shell. In the center of the spiral is the part of the shell that the snail began life with.

The thicker layer underneath is formed from three layers of crystalline calcium carbonate, similar to the chicken egg of which you may be more familiar. The color of the shell depends on the types of food the snail is eating and also the type of snail. Snails can live live from 5-10 years. I thought that was pretty amazing! The oldest snail known lived to be 15 years old. Snails are usually considered to be pests. But snails are also very beautiful and fun to watch. Slugs are shell-less snails and eat plants as well. To tell the difference between a slug and a snail track, look to see if the slime trail is a continuous trail; if so, then it is slug. If the trail has breaks in it, it's a snail.
