Natural.
Everybody involved in herpetoculture loves that word.
I know I certainly did.
Natural enclosures. Natural diets. Natural enrichment. Natural lighting. Natural behaviours.
If something could be described as natural, then surely it had to be better.
Except...
Natural is probably one of the most misunderstood words in this hobby.
It's a conversation I've had more times than I care to remember. Sometimes face to face, but more often hidden away in the comments section beneath a photograph of a healthy animal.
"Those animals should be in the wild."
At first, I'll admit, my responses weren't always my finest moments.
Part of me wanted to reply, "The same could be said about your dog, your cat or your horse. They're simply more socially acceptable."
The other part wanted to ask a much simpler question; Which wild?
The field outside my house in Solihull?
The forests of Ghana?
The Australian outback?
The Madagascan rainforest?
"The wild" isn't a single place. It's thousands of ecosystems, each shaped by millions of years of evolution. Saying an animal "belongs in the wild" is a little like saying someone belongs "somewhere on Earth." It's technically true, but not particularly useful.
Then I stopped answering with sarcasm and started asking myself a different question.
What do people actually mean when they say "natural"?
Because I don't think they're talking about ecology.
I think they're talking about welfare.
And that's where the conversation becomes genuinely interesting.
Nature Doesn't Care About Welfare
Nature, in its very essence, is red in tooth and claw.
It is eat or be eaten. Hunt or be hunted. Survive long enough to reproduce, or don't.
That might sound bleak, but biology has never been particularly interested in sentimentality.
Nature doesn't care whether an individual is comfortable. It doesn't care whether an animal experiences stress, pain or hunger. It doesn't care whether a tortoise survives to old age or whether a snake dies after its first breeding season.
Nature has only one measure of success.
Reproduction.
The theory of evolution by natural selection isn't built upon kindness or welfare. It's built upon adaptation to environmental pressures. Individuals possessing traits that allow them to survive and reproduce pass those traits to the next generation. Those that don't simply disappear from the gene pool.
The environment itself provides those pressures.
Predators.
Parasites.
Disease.
Competition.
Drought.
Floods.
Wildfire.
Starvation.
Every one of these is completely natural, none of them are desirable.
And that's the distinction we often forget.
When people tell me an animal "belongs in the wild," they're usually imagining a healthy snake basking in the morning sun or a tortoise wandering peacefully across an African grassland.
They're rarely imagining the python carrying a heavy parasite burden, the leopard tortoise dying during a prolonged drought, or the juvenile gecko that becomes breakfast for a bird before it ever reaches adulthood.
Those things are just as natural.
Nature doesn't exist to maximise welfare.
It exists to apply pressure. Some individuals survive that pressure. Many don't.
And that's exactly how evolution works.
Natural History Isn't the Same as Natural Welfare
This is where I think people sometimes misunderstand what good husbandry actually is.
When I build an enclosure for a royal python, I don't start by asking myself:
"What tree should I put in here?"
I start by asking a much simpler question.
"What does this animal need to thrive?"
Those are two very different conversations.
I don't set out to recreate a patch of West African forest inside a wooden vivarium. That's impossible. I can't recreate the weather, the seasons, the predator-prey dynamics, the microbial communities or the thousands of subtle interactions that make up an ecosystem.
What I can do is understand why that environment shaped the animal that now sits in front of me.
Natural history gives us those answers.
It tells us why royal pythons seek secure, enclosed spaces. Why they thermoregulate. Why they climb. Why they spend time hidden. Why they become active when they do.
My job isn't to copy the habitat.
My job is to provide opportunities for those behaviours to be expressed safely.
And then... I let the animal tell me what I've got wrong.
That's the part no care sheet can ever do for you.
If the temperatures are wrong, the snake will tell me.
If the humidity isn't quite right, the snake will tell me.
If the enclosure doesn't offer enough security, enough climbing opportunity or enough choice, the snake will tell me.
Not with words.
With behaviour.
That's why I spend so much time watching.
As herpetoculturists, we study natural history because it explains how a species evolved. We then use welfare science to decide which parts of that natural history we should recreate and which parts we should leave behind.
We provide thermal choice.
We provide ultraviolet light where appropriate.
We encourage natural foraging and exploration.
We create opportunities to climb, burrow, bask and hide.
At the same time, we remove predation.
We minimise parasite burdens.
We prevent starvation.
We treat disease.
We reduce unnecessary suffering wherever we can.
That's not making captivity "unnatural."
That's applying everything nature taught us... while refusing to copy the parts that compromise welfare
So, What Does "Natural" Actually Mean?
Perhaps we've been asking the wrong question all along.
Instead of asking whether something is natural, perhaps we should be asking whether it allows the animal to express the behaviours that matter most while experiencing the highest possible standard of welfare.
Because those two things aren't always the same.
Nature gave us the blueprint.
It showed us how these animals evolved, how they thermoregulate, forage, hide, climb, hunt and interact with the world around them.
It also gave us starvation.
Predation.
Disease.
Parasites.
Competition.
Death.
As keepers, we don't have to copy all of it.
In fact, I would argue we shouldn't.
Our responsibility isn't to recreate nature.
It's to understand it well enough to know which parts belong in an enclosure and which parts should remain exactly where they are—in the wild.
For me, natural history has never been the destination.
It's the teacher.
Good husbandry begins by asking what evolution can teach us.
Great husbandry begins by watching the individual animal in front of us and having the humility to admit that sometimes they know more about themselves than we do.
Maybe that's the real meaning of natural.
Not recreating the wild.
Learning from it.
Perhaps that's where herpetoculture gets its greatest strength.
We don't ignore nature.
We study it. We question it. We learn from it.
And then we use everything it taught us to build something better for the individual animal in front of us.
Not because we're trying to improve on evolution.
Because evolution was never trying to maximise welfare in the first place.
