The water
has rules.
The recent headlines didn’t have to happen.
This summer, a woman wading in three feet of river water outside Orlando. A 28-year-old swimming near a resort marina in Mexico. In 2016, a two-year-old boy at the edge of a lagoon, ankle-deep. Three different waters. Same gap every time: nobody had been told what that water actually was.
Nearly every one of them was preventable. Not by luck. By knowing something. That’s the whole reason this book exists: learn where these animals live, how they think and what they can do, and you keep your family safe and the animals wild.
Inside
the book.
The rules the warning signs don’t explain, illustrated with the book’s own field-guide plates, so you understand your surroundings, and the animals that share them, with judgment instead of guesswork.
Know the animal
Alligator, crocodile, or caiman: how to tell at a glance.
The ambush
Only the eyes above the water. What to look for from the bank.
The deadly myth
“It's only two feet deep.” Why depth tells you nothing.
Clear water
Clear water isn't safe water. You just see more of it.
Croc & gator country: fishing & boating
A fish on the line is a dinner bell. Fish and boat their waters safely.
Families
The household rules that keep kids and dogs safe at the water's edge.
Which waters, across the Americas: the U.S. South, the Caribbean islands, and the rivers of Central and South America. If crocodilians live there, assume the water is theirs unless it's posted safe. And even then, keep your eyes up.
Clear, simply told natural history of every crocodilian of the Americas, gators, crocodiles and caimans. Their senses, their seasons, their intelligence, and what that body is actually built to do.
How to behave in their part of the world: at the water's edge, fishing, boating, with kids and dogs, so an encounter never becomes an incident.
The emergency playbook: exactly what to do if the worst happens, for yourself or someone else.
The anatomy of an apex predator.
200 million years of engineering: a divided heart, living armor, night-and-day eyes, a self-renewing mouth, a body that is half muscle. Scroll through the machine on the other side of the shoreline.
Eyes built for ambush.
A vertical slit pupil yawns wide in dark water, then closes to a hairline in bright sun. Day-and-night vision in one eye. A third, clear eyelid slides across underwater like a built-in goggle, so they stay submerged and watching.
A mouth that resets itself.
Around eighty conical teeth built to seize and hold, never to chew. Lose one and a fresh tooth rises within weeks, and they close with one of the hardest bites ever measured.
A four-chambered heart.
A complete wall keeps oxygen-rich and oxygen-poor blood from ever mixing. A fully divided heart no other reptile has, shared only with birds and mammals. It lets a submerged gator slow to a few beats a minute.
Armor that also breathes.
Every raised scute is a plate of solid bone grown inside the skin, and protection you can still bend and swim in. Threaded with blood vessels, they double as solar panels basking and a mineral bank through the longest dives.
The largest reptile alive.
A big saltwater crocodile is a living relic from the age of the dinosaurs: the largest reptile on earth, a lineage that outlasted the giants that died. Stand near one and 200 million years of design stares back.
The engine and the weapon.
Half the animal is a single slab of muscle. That tail launches an ambush from a standstill and can knock a grown person off their feet, which is why distance, not reflexes, keeps you safe.
Two hours. One breath.
Divided heart. Armor. Slit eye. A jaw that rebuilds itself. A tail that's half the animal. Put it together and you get a predator that can hold one dive for two hours. A quiet pond doesn't mean an empty one. It means you can't see the bottom of it.
Croc & gator country is bigger than you think.
From the Carolinas, around the Gulf, into Texas and the corner of Oklahoma. And in south Florida — wild American crocodiles too, the only place on earth the two overlap. South from there, the American crocodile and the caimans range on through the Caribbean, Central and South America — all in the free Americas Edition.
The water
has an owner.
Every pond, canal, and slow river in gator country belongs to something that was here long before us. You don’t have to fear it. You need to respect it, and know that it’s there.
One family. Every warm coast.
Crocodilians ring the warm world — from the American South, across Africa and South Asia, to Southeast Asia and northern Australia. The heaviest human toll falls in sub-Saharan Africa and Indonesia — where people share the water every day, and crocodile education is the scarcest.
Gators, crocs & caimans
The saltwater crocodile
The Nile crocodile
The rest of the family
Around the world the toll isn’t really the animal. It’s infrastructure, and above all education. Plenty of these places had a sign up. Signs get read, nodded at, and walked past. Understanding is what actually changes what someone does, and it’s why every region’s own edition is free to read.
Not a PDF.
A living reader.
The book lives in its own reader. Read it like a film, install it like an app, search it like a field guide, and open it in any language. One book, every way you need it at the water’s edge.
Scroll the book like a film. Every chapter opens over real crocodilian footage.
A quiet, beautifully set reader with the field-guide plates.
Search any chapter for “clear water”, “fishing” or “nests” and jump straight there.
The Americas Edition is free. The $4.99 Worldwide Guide adds Africa and Australasia. Every crocodilian on earth.
It becomes an app on your phone.
The whole book installs to your home screen and opens like an app. No store, no account. It reads fully offline, so it’s with you at the boat ramp, on the trail, and at the water’s edge whether you have a signal or not. And the book keeps growing. Every time we add more, your copy updates itself, free.
We add knowledge as the field learns it. Your copy updates on its own, and every update is free.
Save the whole book. No bars on the water, every page is still there.
Search the book and jump to what you need in seconds: “if attacked”, “nesting season”.
A quick field reference when you're out; a full, deep read at home. Same book.
In your language.
A safety guide only helps the people who can read it, so the reader translates the whole book on the fly. The shorelines where crocodiles take the most lives are rarely English-speaking.
Over 60 years
in the field.
This isn’t internet advice. It’s the working judgment of people who actually handle these animals, written down so your family has it too. Pictured: Tom Crutchfield.

Questions.
What is this book, exactly?
A clear, simply written field guide to the crocodilians of the Americas: the American alligator, the American crocodile, and the caimans of Central and South America. It covers where they live, how they think, the dangerous seasons, the myths that get people killed, how to behave in their part of the world, and exactly what to do in an emergency. Illustrated with commissioned field-guide plates.
Are these animals really that dangerous?
Yes. They're also a lot smarter than people give them credit for, and that's the part that catches you off guard: an animal that reads patterns, sitting behind a bite that ends the argument. That combination is the whole reason the rules exist. Know where they live, respect what they can do, keep your body out of their reach, and almost nothing happens. Not to you, and not to them.
Is the Americas Edition really free? Why?
Really. Every chapter, cover to cover, in the Citadel Culebra reader. The $4.99 Worldwide Guide is what pays for that.
What does the $4.99 Worldwide Guide add?
One purchase opens the whole Worldwide Guide in the reader. Every region on earth. It adds Africa (the Nile crocodile) and Australasia (the saltwater crocodile), with notable attacks and full range maps for each, plus the species atlas and offline reading. One-time, with free updates forever as new regions land.
How does the app-on-my-phone thing work?
Open the reader in your phone's browser and tap the Install button (or Share → “Add to Home Screen”). The cover appears like an app icon and the book opens full-screen. iPhone and Android. No app store needed.
Who is it for?
Anyone who lives, fishes, boats, golfs, or walks a dog where alligators, crocodiles, or caimans live. The U.S. South especially, but the Americas Edition runs from the Carolinas to Texas and on through the Caribbean, Central and South America.

“If we can teach people about wildlife, they will be touched. Share my wildlife with me. Because humans want to save things that they love.”
Twenty years on, he’s still right. He proved that teaching people about an animal protects it better than warning them off it ever did. That’s the bet this whole book is making.
