A Brief Segment of a Snail's Life -Kurzes Segment eines Schneckenlebens

The spiral in a snail's shell is the same mathematically as the spiral in the Milky Way galaxy, and it's also the same mathematically as the spirals in our DNA. It's the same ratio that you'll find in very basic music that transcends cultures all over the world.

Enjoy my new video about this awesome little creature!

Snails are invertebrates, which are animals with no backbones. The shell on the snail helps protect it, and also reduces the loss of water by evaporation. Shells have many different shapes, sizes, and colours. Snails do not breathe through their mouths, instead they have a breathing hole under their shells.

As the snail grows, so does its calcium carbonate shell. The shell grows additively, by the addition of new calcium carbonate, which is secreted by glands located in the snail's mantle. The new material is added to the edge of the shell aperture (the opening of the shell). Therefore the centre of the shell's spiral was made when the snail was younger, and the outer part when the snail was older. When the snail reaches full adult size, it may build a thickened lip around the shell aperture. At this point the snail stops growing, and begins reproducing. A snails "foot" is a muscle which allows it to move slowly across the ground. The foot puts out ('exudes') slime, which eases the snail's movement, leaving a trail. Snails can absorb mineral nutrients through their foot by simply sitting on a rock containing it.

The head is attached to the foot. The mouth is like a cheese grater. It is called a radula. It is used for cutting food. On the radula there are little teeth. On the head there are 15 mm stalks. At the end of the stalks are snail’s eyes, though they do not see very well.

The snail family is big and believed aprox. 200,000 species of mollusks (incl. Snails),  50,000 classified.

The interaction in nature has always fascinated me. Everything has its purpose and task, as we humans would have too, if we wouldn’t have got alienated so considerably from the original nature.
