The wonders of sea life through the eyes of a physicist
Encounter a life form completely different from ours

“Humans have deciphered some of our most secret technologies,” said the mermaid.
“How on earth did you find out all this information?” asked the octopus.

“They seem to have a very efficient extension cord.
“One is biology and the other is physics.”

Giant sperm whales and giant squids leisurely diving into the deep sea, schools of anchovies changing formations to confuse predators, flying fish leaping from the seawater and gliding above the surface… … .
The way marine life survives is very different from that of terrestrial life, as their environments are different.
What does the marine world look like? While much is unknown about the ocean compared to land, the underwater world still fascinates us.
"Geniuses of the Sea" is a book that explores the wondrous abilities of sea creatures from a physicist's perspective.
If biology acts as a kind of magnifying glass by classifying living things and describing the functions of every part in detail, physics, by its nature of trying to explain everything through laws, tries to find simple principles that permeate all entities.
Physicist Bill François, fascinated by marine life, uses his signature humor and metaphors to convey the physical characteristics of the underwater environment and the survival skills of marine life adapted to it in a delightful way.
Through vivid illustrations created with meticulous observation and sophisticated techniques, we explore the amazing abilities of sea creatures that live in ways that are different from our own.


Why is the world's largest animal in the ocean?
There's a physical reason for the appearance and survival skills of sea creatures.

The largest animal in the world is known as the blue whale.
The largest land animal of all time, the dinosaur Argentinosaurus, is estimated to have weighed around 80 tons, while the blue whale weighed twice that much.
Why don't creatures the size of a blue whale exist on land? There's a physical reason for this.
Because terrestrial organisms are affected by gravity.
Animals need muscles to move, but if the weight of the muscles increases, the bones will have a hard time supporting it, and if the skeleton increases along with the muscles, the body will become heavy and impossible to move.
Ultimately, giant animals are bound to be found in the ocean, where they are relatively free from the influence of gravity.

This book introduces various species of creatures that have evolved in the underwater environment of the ocean, and explains their appearance and survival techniques from a physicist's perspective.
From a physical perspective, such as matter, force, and energy, the underwater environment has very different constraints than the terrestrial environment where we live, and marine life has evolved to develop a lifestyle suited to the underwater environment.
Through this book, you can vividly experience the lives of marine life, including tiny fry that experience swimming in honey as soon as they are born, tuna that can never stop swimming, flying fish that break through the water's surface, and bioluminescent animals that emit light in the dark deep sea.
You will come to realize that marine life is precious in itself as a part of nature.


From the invention of the battery to the invisibility cloak and the secret to staying young.
The extraordinary abilities of sea creatures to expand human knowledge

Considering that we struggle to survive underwater for even a few minutes, the sheer number of creatures that roam the ocean is truly awe-inspiring.
Marine life has always aroused curiosity and wonder, and as we explore the secrets of their extraordinary abilities, we naturally acquire knowledge about their principles.
The discovery of the electric ray's mysterious abilities gave birth to a new scientific field called electrophysiology and led to the invention of the first battery.
Today, it is known that the silvery layer of anchovy skin reflects light like a mirror, allowing the fish to blend into the background and disappear, offering very promising possibilities for engineers designing equipment.
Additionally, biologists have discovered that lobsters, which live up to 200 years, maintain their youth by producing an enzyme called telomerase throughout their body's cells throughout their lives, which prevents chromosome damage, unlike mammals.
This book shows how simple principles discovered in the diverse abilities of marine creatures can open up new possibilities for us.
From the logical rules of pattern patterns on fish bodies and shells, to the collective intelligence discovered in the movements of schools of fish, to the senses of sharks that detect the movement of water throughout their bodies, this book will expand your thinking by observing marine life at the intersection of biology, evolution, and physics.

Where can you apply your knowledge of marine life?
Why We Need Wisdom to Live Together

Krill, a tiny vegetarian shrimp, and whales, a massive animal, play a vital role in processing carbon, a major contributor to the climate crisis.
Carbon dioxide in the atmosphere dissolves into the ocean surface, and phytoplankton convert the carbon dioxide dissolved in the water into organic matter through photosynthesis.
Krill consume these phytoplankton and capture some of the carbon dioxide within their bodies.
The role of krill in contributing to the Earth's climate is demonstrated in the following process: the shells shed during molting and the excrement they excrete accumulate and remain at the bottom of the deep sea.
You might wonder how much impact these tiny creatures have on the Earth's environment, but their numbers are staggering, processing an estimated 23 million tonnes of carbon in the Southern Ocean alone.
Meanwhile, whales eat more than 6 tons of krill every day, fixing carbon dioxide into their bodies.
Later, when the whale dies, the carbon sinks to the bottom of the ocean along with the whale's body.

Throughout the book, author Bill François raises awareness of the extinction of marine life and the ecological crisis caused by overfishing and habitat destruction.
Horseshoe crabs are hunted by the thousands in the United States alone today for their blood, which is believed to be useful in vaccine testing, but only recently has a synthetic substitute been developed.
Less than 50 years after the discovery of hydrothermal vents on the seafloor, investors and industrialists seeking to exploit the minerals are preparing to apply for mining permits, while scientists and international nongovernmental organizations are working to slow the process.

In this book, the author points out that knowledge about marine life can be a force that destroys nature or a force that saves nature, depending on how we use it.
Krill and whales may not be able to solve global warming, but if more people recognize that many marine species play a role in the carbon cycle, we can work together to find ways to use the oceans to protect them.
Let's meet the colorful creatures living in the sea through this book.
This book, imbued with a love for marine life, will make the wonder itself a compelling reason to protect the marine ecosystem.
