And sulphur is a key ingredient in slug pellets and it's very dangerous, poisonous for snails.
So actually the scales have this, again, a nanostructure in them, a bit like the nacre we talked about.
A lot of it comes down to these nanoscopic structures in the shells.
They act like little tailpipes on a car exhaust and then...
They draw that sulfur out of their body and it reacts with iron in the water around them and lays down this iron layers.
So in fact, it's the snail protecting themselves from this sort of internal poison so that they can exist in this crazy place.
Yes.
There you go.
