A sparkling abyss. What secrets does the ocean hide and what threatens its deep-sea inhabitants?

What does the dark, deep abyss hide within? And what impact does the aquatic ecosystem have on our daily lives?

Popular marine biologist Helen Scales knows the answers to these questions.

The depths of the sea are fraught with many wonders, but... all this will soon be gone. Perhaps, along with our planet.
The book's author, a marine biologist, talks about the most amazing part of our planet, whose topography is even more diverse and extreme than its terrestrial counterpart.
This is the realm of jelly-like creatures, so fragile that they disintegrate when touched and ooze through your fingers when you try to pick them up.
This is colossal pressure that can destroy the cells of our body, but does not cause any harm to deep-sea creatures.
Billions and trillions of small luminous fish live here, constantly scurrying in schools up and down.
Worms more than two and a half meters long live here, crabs dance, and snails grow armor that is not inferior to metal armor.

Fantastic creatures living in the deep capture and sequester vast amounts of carbon that would otherwise poison our atmosphere; and new, undiscovered bacteria promise to create powerful new drugs. But deep-sea mining, fishing, oil drilling - all this will soon completely destroy the marine ecosystem, leaving our world vulnerable and empty. In this book, Helen Scales explains in clear, accessible language why the ocean is so important and valuable to the planet and our survival.
