So whether that's a shell or whether that's the arms of an expanding galaxy or the seeds in a sunflower or a moth flying towards a candle towards its doom, we see this sort of shape come up again and again.
And I guess it is just that kind of fundamental, this is what happens.
There must be something in the process of how shell, how mollusks make their shells, which they do throughout their lives.
Actually, I guess that's an important point, which is unlike, say, crabs or lobsters, which have also got these hard outer layers.
They molt them and they get rid of them, grow a new bigger one.
And that's how their bodies grow bigger.
Whereas mollusks keep the same shell their whole lives.
The tiny central piece, the middle of that spiral is the shell it had when it was a baby shell.
And then it just kept making it bigger and bigger and expanding that open end, the circle, if you like, that's the open hole of a shell, a snail shell, is where it grows from.
And it just keeps getting bigger.
And I guess it is just that sort of rate of expansion keeps going and voila, you get a spiral.
Jeremy, I think, was very rare because the thing is, if you grab a shell and have a look at it, look at the next time you find a garden snail, have a look.
What way is that spiral turning?
Look at it from the top again.
Is it going clockwise or anticlockwise?
Most mollusk, most gastropod shells are clockwise turning.
They are right turning shells.
But you get occasional rarities like Jeremy who spin towards the left.
So he was a lefty.
And the problem that comes with this is that it isn't just the shell that is spiralling in a certain direction.
