Founding class of 2026Citadel Culebra

Somebody had to teach this.

Reptile keeping has been a serious pursuit for sixty years and there is still no accredited path into it, no credential anyone recognises, and no room where the people who know sit down and teach it in order. So we built the room. Fourteen disciplines, faculty who have kept these animals their whole working lives, and a door that opens for free.

Why this exists

It starts with Steve.

Ask around a reptile room long enough and you find the same answer sitting under most of the people in it. A man in khaki shorts, on a television, completely delighted about an animal everybody else in the room was afraid of.

He never belonged to one country. He belonged to whoever watched him and decided the thing in the grass was worth understanding instead of killing.

And the argument he made his whole life was a simple one. Teach somebody about an animal and they will look after it.

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.
Steve Irwin · The Crocodile Hunter: The Incredible Life and Adventures of Steve and Terri Irwin, 2002

That is a curriculum. It is the whole thesis of a school, said in three sentences by somebody who never got to build one. Twenty years later the reptile world still has documentaries, forums and a hundred thousand hours of video, and no institution. We got tired of waiting for one.

Citadel Culebra has no affiliation with Steve Irwin's family, his estate, or Australia Zoo, and claims none. We quote him because he is the reason a lot of us are in this at all, and we would rather say that out loud than borrow the association quietly.

The gap

You can get certified in almost anything else.

There is a certificate for keeping bees. There is a licence for a forklift. There is a two-year program for grooming dogs. Keep a fourteen-foot reticulated python, or a monocled cobra, or a room with a hundred and forty animals in it, and there is no program that ends in anything a single person recognises.

01

Nobody accredits this

No agency certifies reptile knowledge. There is nothing to be accredited by, which is why the school says out loud what its standard actually is: the faculty. One expert can be wrong. When McCurley, Crutchfield, Park and Van Horn all tell you the same thing, that is as certified as this field gets.

02

Hot work is learned off a phone

People teach themselves hook work and tube work alone, at eleven at night, from a video shot by somebody they have never met. Then they find out what they got wrong on the day it counts. That is not a character flaw and we are not going to pretend it is one. It is what happens when nobody offers the class.

03

And the beginner has the same problem

The keeper with one bearded dragon who cannot get a straight answer about UVB distance is standing in the same building as the man with the cobra. The stakes are nothing alike. The missing class is identical.

So the school is built at both ends at once.

Where you would start

Two ends of the same building.

Somebody who wants a hand with one animal, and somebody who wants to work hot. Both are real destinations. Most people land somewhere between them and move along at whatever speed the animal in front of them allows.

01 · Coaching
Coaching

One animal, one problem, a straight answer

You have a beardie, or a ball python, or a tortoise, and you want somebody who actually knows to look at what you have built and tell you the truth about it. No course to finish first. This is the most common reason people walk in and there is nothing junior about it.

  • Your setup, reviewed
  • Ask the faculty directly
  • No prerequisite
02 · The core
The core

The four everything else is built on

Husbandry, nutrition, behaviour, anatomy. Gradients and humidity. What the animal is actually telling you before it strikes. How the body works, so an early sign reads as a sign instead of a mood. Take these in order and the rest of the curriculum stops being a pile of tips.

  • Four disciplines
  • Sequenced, not sampled
  • Signature credential
03 · Specialty
Specialty

The thing you are actually into

Breeding and genetics. Veterinary awareness and when to stop guessing and call someone. Running a collection rather than owning one. Field work and conservation. Pick the direction, go deep, come out with a credential that names it.

  • Ten more disciplines
  • Multi-faculty
  • Specialty credential
04 · High-risk
High-risk

Venomous, and the animals that do not forgive

Hooks and tubes, cage design, lock discipline, the protocol you write and tape to the wall before you ever need it, and what actually happens on the worst day. Taught by people who have spent their working lives on the hot side of the glass. There is a gate on this one. There should be.

  • Gated entry
  • Written protocol

How it gets taught

We film in the room,

with the animal out.

No studio, no stock, no borrowed footage, nothing generated. If you see a room on this page, we stood in it. If you see a person, they said the words themselves.

Who teaches it

The accreditation is the faculty.

There is no agency to be certified by, so the standard has to be the people. These are working keepers and breeders with decades behind them, filmed in their own rooms, on the days we were there.

What you study

Fourteen disciplines. One school.

Every page in the library files under one of them, basic care at one end and mastery at the other, with a credential at each rung that names which one you actually reached.

The first class meets on a call.

No campus, no travel, no dress code. Brax walks the academic calendar for the year, the faculty come on and say what they are teaching and why it is theirs to teach, and then it is an open floor. If you are enrolled you get the link. If you are still deciding you can sit at the back and listen.

  1. 01The academic calendarThe whole year — when each discipline opens, when exams sit, when the books land.
  2. 02Meet the facultyThe instructors come on themselves rather than being introduced by a slide.
  3. 03What we are actually buildingThe library, the database, the courses, and what comes after them.
  4. 04Questions, liveOpen floor. Ask people who have kept these animals for forty years.

Free, online, and you do not have to be enrolled to sit in.

Before you spend anything

Three things you can do in the next ten minutes.

The school opens properly in September and the courses are behind a door we are still finishing. None of that stops you starting tonight, because the front half of this is free and it is going to stay free.

01Free

Look up any species on earth

10,406 records with taxonomy, range and conservation status, each one stamped with where it came from and when it was last checked. Where there is no record it says so instead of inventing a paragraph.

No account. No email.

Open the database
02Free

Read a whole book, free

Croc & Gator Wise in the Americas edition and The Bearded Dragon are free to read right now, front to back, in the same reader the paid titles use. It works on a plane and installs to a home screen.

Starts in one click.

Open the library
03Free

Walk through the community before you join

Spaces by species and by discipline, the threads, the faculty. You can read the whole thing as a visitor and decide from the inside, which is the opposite of how every other community in this field works.

Browse first, join later.

The Complete Keeper Membership · Founding Class of 2026

One tuition. Every discipline, every book, every instructor.

The school is the whole thing, not a course you finish. Tuition carries the library, the courses, the database, the collection software and the room where the faculty answer questions in the open. The founding rate is locked for as long as you stay enrolled.

If you want a cheap pet and a YouTube video, you do not need us. This is for people who are in it for the animal's whole life.

  • Every book in the Codex, including the ones still on the press
  • Every course, every exam, every certificate
  • The species database and the research layer
  • Culebra Connect, where the faculty answer questions in the open
  • Cerebro Culebra for your own collection records
  • Culebra Chronicles, the newsletter, registered automatically

Billed $79.99/month. Your membership renews automatically each month until you cancel. Cancel anytime — no future charges.

Manage or cancel anytime in your account.

Orientation is September 9. Enrol before it and you are in the first class, at the founding rate.

Or $799 a year at the same founding rate, which is $160.88 less than paying by the month.

Founding tuition is locked for the first 15,000 founders and stays locked for as long as you stay enrolled. When those seats are gone the rate is gone, and everyone after joins at $99.99.

No money-back guarantee, on purpose.

We cannot do the husbandry for you and we are not going to pretend otherwise. So instead of a refund promise, the front half is free and always will be: the whole species database, the free books, and the community to walk through before you make an account. Look at all of it, then decide. And if you do enrol, one click cancels and you are never charged again.

Read the curriculum first
Start free

Walk in for nothing first.

The species database is open to anyone, no account. So are the free books. Leave an email and you hear from us when a title comes off the press, and you can leave from the bottom of any email.

One email when something ships. No ads, no list rental.

Straight answers

Before you ask.

01Is this accredited?

No, and neither is anyone else, because no agency certifies reptile knowledge. We would rather say that plainly than invent a seal. What the school has instead is the faculty: people who have kept, bred and worked these animals for decades, teaching the same material in the same sequence, with their names on it.

02I have one bearded dragon. Is this for me?

Yes, and that is the first rung on purpose. Most people walk in with one animal and a question nobody has answered straight. You do not have to want a collection, or a business, or a cobra.

03Can I actually learn venomous keeping here?

The venomous track is real and it is taught by George Van Horn, Steve Angeli, Tom Crutchfield and Kevin McCurley. It is also gated, and it should be. No course replaces a mentor standing next to you the first time you hook an animal, and the curriculum says so rather than pretending otherwise.

04What does it cost?

Founding tuition is $79.99 a month, or $799 a year, locked for the first 15,000 founders and held for as long as you stay enrolled. After those seats it is $99.99. The four credentials can also be taken on their own at $199, $349, $499 and $799. The species database is free to anyone, forever, and so are the books we open in front of the paywall.

05When does it start?

Orientation is Wednesday, September 9, online and open to whoever turns up. The academic calendar for the full year is published the last week of August.

06What happens if I cancel?

You cancel in one click and you are not charged again. Your access runs to the end of the month you already paid for. Nothing you wrote goes away — notes, highlights and records export as plain files whenever you ask for them.

Citadel Culebra

Teach somebody about an animal and they will look after it.

That was his whole argument and nobody ever built the school for it. Start with the part that costs nothing.
