Book cover of The Soul of an Octopus: A Surprising Exploration Into the Wonder of Consciousness

Rachel G. Jordan Author Of If the Ocean Has a Soul

From my list on diving into the Christian faith and science.

Why am I passionate about this?

I am a Jesus-loving coral nerd with a passion for helping people learn science accurately, represent Jesus fully, and engage in conversations respectfully. Having previously worked as a coral biologist for the US National Park Service, I have an MS in marine biology and ecology from James Cook University (Australia), a BS in ecology from Seattle Pacific University (USA), and a certification in biblical studies from Bodenseehof Bible School (Germany). When not diving or writing, you can find me reading C.S. Lewis, growing wildflowers, and hosting faith and science conversations on Instagram (@shorelinesoul) or at rachelgjordan.com. 

Rachel's book list on diving into the Christian faith and science

Rachel G. Jordan Why Rachel loves this book

If you ask a marine biologist for a book recommendation, more likely than not, they will hand you this book about octopuses. But far from a simple book about charismatic underwater aliens, this book delves into a beautiful, philosophic inquiry of the natural world and the role of humans within it. 

Using journalism-based storytelling with hands-on experiences, this book emphasizes the profound intelligence, emotional depth, and individual personalities of octopuses. Although the book doesn’t directly address the intersection of faith and science, its key message carries important implications for those who desire to connect spirituality with nature.

This cathartic read will stimulate your fascination with marine life while interweaving philosophical reflections toward the ultimate goal of realizing our connection to these incredible creatures.

Book cover of The Sound of the Sea: Seashells and the Fate of the Oceans

Sandy Sheehy Author Of Imperiled Reef: The Fascinating, Fragile Life of a Caribbean Wonder

From my list on the amazing world of coral reefs.

Why am I passionate about this?

For more than four decades, Sandy Sheehy has been diving tropical coral reefs from the Caribbean to Australia. Starting when she was around five sitting in her pediatric dentist’s office where she noticed an aquarium stocked with colorful fish, her fascination with the underwater world has grown. Becoming a freelance journalist allowed her to call on experts and activists around the world to help her satisfy her curiosity and share what she learned.

Sandy Sheehy Why Sandy loves this book

In clear, evocative prose, Barnett describes the world of seashells and humans’ relationship to them. Her book was laced with “Who knew?” moments for me. For example, until recently people considered seashells a kind of rock, giving little thought to the creatures that built and inhabited them. Barnett explains the threat that rising carbon dioxide levels present to the formation and very existence of shells, but she never carps; and although she interjects some of her own experiences—and sense of wonder—she never lapses into making this book about her, rather than her subject.

2 authors picked The Sound of the Sea as one of their favorite books, and they share why you should read it.

What is this book about?

Seashells have been the most coveted and collected of nature's creations for thousands of years. They were money before coins, jewellery before gems, art before canvas.

In The Sound of the Sea, Cynthia Barnett blends cultural history and environmental science to trace our long love affair with seashells and the hidden lives of the mollusks that make them. From the mysterious glow of giant clams to the surprising origin of Shell Oil as a family business importing exotic shells, the book is filled with unforgettable stories. As it explores the perfect symmetry of a Chambered Nautilus, the pink-glossed lip of…


Book cover of Spineless: The Science of Jellyfish and the Art of Growing a Backbone

Erin Zimmerman Author Of Unrooted: Botany, Motherhood, and the Fight to Save An Old Science

From my list on memoirs by women talking biology.

Why am I passionate about this?

As an evolutionary biologist and an advocate for women, and in particular, mothers in the sciences, I love to read about the stories of other female scientists talking about their work and the challenges they’ve faced. We need more accounts of what it’s like to grapple with both the idea and the actuality of becoming a mother in a competitive, male-dominated field that requires so much of its scholars.

There’s a line near the beginning of Berwald’s book where she mentions that jellyfish came into her life “when the haze of sleepless nights” brought on by early parenthood had begun to lift, and she was beginning to once again have an existence beyond parenting. What follows is a chronicle of Berwald’s deep dive into all the fascinating aspects of her new passion and the people and places she experienced because of it.

I read this book while I was living in that very haze, and enjoyed both following Berwald’s adventures and imagining those that I’d have once my haze had lifted.

That’s right: that Charles Darwin, the author of The Origin of the Species. Seventeen years before that ground-shaking book, he wrote what marine scientists tell me remains the definitive work on the structure of coral reefs. Forget the famous Punch caricature of the gray-haired man trailing a long beard and a chimpanzee and think of the youthful naturalist daring crashing waves to vault to the edge of a South Pacific fringe reef. In places his accounts read like True Adventures for Boys.

What is this book about?

Charles Darwin Collection

Charles Robert Darwin FRS was an English naturalist who realised and presented compelling evidence that all species of life have evolved over time from common ancestors, through the process he called natural selection. The fact that evolution occurs became accepted by the scientific community and much of the general public in his lifetime, while his theory of natural selection came to be widely seen as the primary explanation of the process of evolution in the 1930s, and now forms the basis of modern evolutionary theory. In modified form, Darwin’s scientific discovery is the unifying theory of the…

Book cover of The Big Book of the Blue

Cassandra Federman Author Of This Is a Sea Cow

From my list on children’s stories about ocean animals.

Why am I passionate about this?

I've been fascinated by the ocean and all of its inhabitants for as long as I can remember. When I was little, I discovered my dad’s SCUBA license and it blew my mind that I was related to someone who was allowed to explore the underwater world! Later, when I got to college, I took advantage of two exciting opportunities. First, I got my own scuba license. Second, I studied abroad in Belize, where I conducted manatee research by tagging, tracking, and rescuing manatees. I enjoyed the time I spent with the animals, but not the lab work. Now I express my passion for sea creatures in the books I write.

This book is full of fascinating facts about all kinds of sea creatures from those near the surface to those who live down deep in the darkness. For me, the biggest draw of this book is the illustrations. (Pun intended!) The art is so full of texture and color and every page is as gorgeous as the one that came before. This book is a feast for the eyes and the curious brain!

Book cover of The Sea, the Storm, and the Mangrove Tangle

Emily Dangremond Author Of Meet the Trees

From my list on trees from a plant ecologist.

Why am I passionate about this?

It was disappointing comparing the rich diversity of animals on colorful book pages to the reality of forests, where I could only see trees. But as I learned about plants and I became a plant ecologist, I realized that plants have to be extremely tough because they can’t run away from dangers or animals who want to eat them. I studied plants in coastal habitats in California, Central America and Florida, and in forests in the Midwest. I love seeing how they change throughout the season and how they interact. I wish everyone would read as many books about trees as construction trucks!

Emily's book list on trees from a plant ecologist

Emily Dangremond Why Emily loves this book

I love how detailed this book is, bursting with species to learn about. Nature can be a beast. What happens when a hurricane hits and ocean animals have their home turned upside down? I was on the edge of my seat, wondering what would happen to the animals. I love that the book shows how mangroves are trees that form a refuge in a storm.

This book is illustrated with intricate details of mangrove plants and the animals they host, making me want to grab my mask and snorkel and catch the next flight to the Caribbean to see them. Full disclosure: I studied mangroves for over 10 years, so I am biased, but they are really awesome trees.

A look into a unique ecosystem, one that is endangered in many places

A seed is jostled from a branch of a mangrove tree and floats to a lagoon in the Caribbean Sea. It takes root, sprouts leaves, and slowly begins to grow. Over many years, the mangrove will provide a home and nourishment for numerous creatures of land and sea. Among its roots come to live fiddler crabs and shrimp; in its branches dwell lizards and hummingbirds. Soon the tree is dropping seeds of its own, and other mangroves are growing, creating a tangle whose benefits extend even to…

Alyssa Clements Author Of The Size of Everything: Ginormous Galaxies, Itty-Bitty Quarks, and Me

From my list on children’s science for Christian families.

Why am I passionate about this?

I’m a third-grade teacher turned book editor and writer who loves learning about the fascinating world God has made and exploring how it all points back to him. During my time in the classroom, I worked at a Christian classical school where my grade’s scientific focus was astronomy. I loved introducing my students to this awe-inspiring, gigantic universe that we are a part of and considering together just how big, powerful, and loving God must be to have designed and created it all. I am also mom to two wonderfully curious children who love to read, explore, and ask big questions.

You cannot go wrong with any of the board books in the Hello, World! series.

This one about ocean animals is a recent go-to in our home, and I was fascinated to learn that octopuses have three hearts, blue blood, and nine brains! With bright illustrations and easy-to-understand yet captivating scientific information, these books are wonderful for curious, young scientists eager to learn about God’s world.

My kids also love the Solar System and My Body books in this series. There’s no age too young to start teaching our kids about the intricacies of God’s creation, and this series is an excellent resource for families looking for engaging, scientifically rich books that do just that.

Book cover of Starfish

Amorina Kingdon Author Of Sing Like Fish: How Sound Rules Life Under Water

From my list on water is a gateway to a strange new world.

Why am I passionate about this?

I have always been obsessed with the idea of other worlds I can’t sense but can somehow contrive to glimpse, whether with a magic amulet or some fabulous technology. As a kid growing up in the woods and devouring fantasy novels and biology texts alike, I couldn’t decide between science or writing as a way of exploring the unknown, and ultimately, I ended up doing both: becoming a writer specializing in marine and coastal environments, one of the many places in our world where the deeper we look at the senses of the creatures living there, the more we realize just how limited our own perceptions are. 

Amorina's book list on water is a gateway to a strange new world

Amorina Kingdon Why Amorina loves this book

This book is claustrophobic, unflinching, and horrifying, so I can’t watch videos from seafloor subs, drones, or observatories. I’m used to sci-fi that takes place in the cold black isolation of a spaceship, but here we have the cold black isolation of the seabed, which triggers all the thalassophobia. Add the meticulous routines of a crew surviving in a place where humans shouldn’t be and, above all, the awful psychological pull of the void, and you get deliciously potent nightmare fuel.

But maybe more than that, I love that Watts is one of those authors, like Richard Morgan, who creates spec-fic characters with questionable morality, who can and do alarm the reader. Everyone I know who’s ever read this book has never forgotten it, shudders when I mention it and knows who Lenie Clark is.

So when civilization needs someone to run generating stations three kilometres below the surface of the Pacific, it seeks out a special sort of person for its Rifters program. It recruits those whose histories have pre-adapted them to dangerous environments, people so used to broken bodies and chronic stress that life on the edge of an undersea volcano would actually be a step up. Nobody worries too much about job satisfaction; if you haven't spent a lifetime learning the futility of fighting back, you wouldn't be a rifter in the first place. It's a small price to keep the lights…

Book cover of Sex in the Sea: Our Intimate Connection with Sex-Changing Fish, Romantic Lobsters, Kinky Squid, and Other Salty Erotica of the Deep

Danna Staaf Author Of Nursery Earth: The Hidden World of Baby Animals and the Amazing Ingenuity of Life

From my list on babies and parenthood throughout the animal kingdom.

Why am I passionate about this?

Like most children, I adored baby animals from an early age. I bonded deeply with a pet kitten; I campaigned (unsuccessfully but perennially) for a puppy; I delighted in caterpillars. In college, my biology classes introduced me to a profusion of marine larval forms, and a fascination with the true diversity of animal babies fully gripped me. I eventually earned a PhD in the biology of squid babies and, shortly afterward, produced two human babies of my own. I now live with my human family, a cat, and a garden full of grubs, caterpillars, maggots, and innumerable other babies. I read and write about science and nature, especially the intersection of the weird and the adorable.

Danna Staaf Why Danna loves this book

Similar to Dr. Tatiana’s Sex Advice, this book made me laugh and gasp at scandalous true stories of reproductive biology. What really captured my attention, though, were the unexpected ways that human actions are affecting the courtship, mating, and spawning of animals that might seem beyond our reach.

Knowing that we can unintentionally inhibit the intimate lives of other species through pollution and climate change really brings home the importance of reforming our behavior.

Forget the Kama Sutra. When it comes to inventive sex acts, just look to the sea.

Deep-sea squid perform inverted 69s, while hermaphrodite sea slugs link up in giant sex loops. From doubly endowed sharks to the maze-like vaginas of some whales, Sex in the Sea is a journey unlike any other to explore the staggering ways life begets life beneath the waves. Beyond a…
