In this bedtime story, I take you on an underwater cruise to the various layers of the Earth's oceans. I talk about marine life, its evolution, and the conditions it had to adapt to. Types of animals or species we look at in more detail include jellyfish, coral, sharks, giant squids, sperm whales, the components of plankton, fishes from the bathyal zone and below, or the inhabitants of ecosystems around cold seeps and hydrothermal vents. We also make a bit of time travel, and I tell you about some of the largest creatures that dominated our seas from the Cambrian period to today: trilobites, anomalocaris, sea scorpions, placoderm fishes, plesiosaurs, ichthyosaurs, mosasaurs or megalodons.
