How do creatures in Movile Cave survive?

By using chemical energy from hydrogen sulfide in place of the radiant energy of sunlight, a peculiar class of bacteria called chemoautotrophs not only survive but furnish food for higher organisms. All the animals in the cave have lost their ability to see, and their bodies have lost all pigmentation.

Can humans smell rain better than sharks smell blood?

The scent of rain, petrichor, has two main constituents with actual chemical names and origins – ozone (O3) and geosmin (C12H22O) and humans can sense it at 5 parts per trillion. Trillion! Which means that humans are 200,000 times more sensitive to smelling geosmin than sharks are at smelling blood.
