In nature every death brings new life. A fascinating example are whale-falls: when a whale dies, its carcass will sink down to the ocean floor where it creates a unique ecosystem for bottom-dwelling organisms. Whales’ bodies can weigh up to 200 tons and contain massive amounts of fat and proteins. When a dead whale reaches the ocean floor it brings a lot of resources to an environment which is usually limited by food availability. The fortunate creatures experiencing the whale-fall welcome such a great source of nutrition, and use up everything they can, until the last vertebra is decomposed.

Earth is a fountain of incredible abundances and varieties of life-forms, with many of them still undiscovered. Biodiversity is a key pillar for our life as we know it, and we are not only a small fraction of it, but also use and harness this richness for the benefit of our own species’ advancement. Many human advances are based on other organisms’ attributes and talents, which is why we use certain species as “model organisms” when pioneering scientific breakthroughs. One example of such a specific form of life has helped us make some serious inroads into forms of regeneration and even immortality over the last few billion years ago, and leading us to great discoveries in science.
