Looking at a crested gecko, it may be a little hard to conceive that it could be an animal with high intelligence.

And although there has not been much experimentation or study done in this arena, recent studies have been disproving the previous claims that a crested gecko is incapable of higher cognitive abilities.

Are crested geckos smart pets?

It is now being claimed that both species – the crested gecko and the leopard gecko – popular among enthusiasts and pet owners who prefer reptiles, have shown the capacity to develop higher cognitive abilities that allow them to escape predators and have a better chance of survival in the wild.

4 Reasons Why Crested Geckos May Be Smart

Now, here’s the thing – we human beings get a little cocky when we talk about terms like intelligence and cognitive abilities.

We instantly start using our levels of cognition and our forms of intelligence as the golden standard.

But that is not how nature works. In the wild, intelligence and cognitive abilities go beyond the humanly defined tests and parameters.

It becomes pertinent to factor in things like inquisitiveness, problem-solving, spatial cognition, social cognition, etc.

Keeping this in mind, here are 4 reasons that could be a piece of substantial evidence in proving that crested geckos are indeed smart and intelligent animals:

Reason 1 – Abilities of Danger Avoidance and Self Preservation

Let us tackle this one by one.

First, we take into consideration danger avoidance. Now, at first sight, it may seem like danger avoidance is a natural consequence of every animal’s survival instinct.

While that is true, a crested gecko goes a step further and knows full well that to truly be safe and invisible from its predators in the wild, it will have to hide its tracks too!

One such example of danger avoidance is the tendency of a crested gecko to consume its shed skin.

Not only does the shed skin have a small amount of the required nutrients, but also, a crested gecko knows that leaving any shed skin behind will hint to the predators about its position.

Now, let us look at behaviors of self-preservation.

A crested gecko knows and prioritizes the preservation of self over everything else. As humans, we may think that the only thing that can lure any animal out of hiding is food.

But crested geckos are smarter than to give in to a momentary want of food.

In fact, during winters, when food is in short supply and it is easier for them to get predated than to prey upon, crested geckos tend to undertake to fast and slow down their metabolism. This allows them to survive the harsh winters in hiding.

Reason 2 – Reproductive Intelligence of Female Crested Geckos

Female crested geckos show 3 amusing and intelligent behaviors when it comes to mating and reproduction:

Rejecting a mate.

Unlike most female animals, a female crested gecko does not give in to the whims of any and every male crested gecko that approaches her with the intent to mate.

She is selective about the “father” whose genetics will provide a strong survival chance for her babies.

Storing sperm for over a year.

Now, this is one of the most surprisingly smart abilities that a female crested gecko has. She can store the sperm `inside her for more than a year.

This way, she can choose to lay her eggs when she feels the safest and when she thinks the time is right.

Cryptic Female Choice.

If the point of sperm retention hasn’t convinced you yet, this last one just might.

A female crested gecko can choose to not fertilize her eggs with the sperm of a male crested gecko if she feels the sperm has a low chance of fertilizing her eggs.

In this way, she simply lays infertile eggs, which she can later ingest to reabsorb the nutrients and ensure that she does not become malnourished due to reproducing malformed eggs.

Reason 3 – Spatial Cognition

Now, while it is easy for us to claim that spatial cognition is a common survival behavior that every animal possesses, it may be worthwhile to know that a crested gecko’s spatial cognition is so developed that it can even cross a maze!

That is indeed true. A baby crested gecko may be better at navigating through a maze because of their heightened inquisitiveness and alertness toward the surroundings.

Reason 4 – Communication Skills

A crested gecko, despite being infamous for being a solitary creature, actually can communicate with other geckos vocally, physically, and chemically. Crested geckos have a range of vocalizations – chirping, barking, squeaking, etc. – and quite often, each of these vocalizations is used for expressing a different set of emotions.

Moreover, crested geckos communicate about their territory and mating urges through pheromones as well!

Can Crested Geckos Recognize Their Owners?

A crested gecko can remember and recognize its owner – but not exactly in the way you would imagine.

A crested gecko cannot recall or remember you by your face or any other visual cues.

But, over time, your pet crested gecko will get used to your scent and your voice – and that is how, bit by bit, your pet will acclimate to your presence by associating you with positive experiences, mostly related to food.

So, while the bad news is that there is no scientific literature that can prove whether your crested gecko can visually recognize you or not, the good news is that your pet has other sensory ways to recognize you and differentiate you from other human beings.

Do Crested Geckos Have A Memory?

The first thing we need to clear when we speak of a crested gecko’s memory is how we define memory.

Now, as humans, we often think of memory as the things we can recall, moments of joy and grief that we remember, and the people we love and hate. But that is not entirely how crested geckos function.

When we speak in strictly biological terms, then a human being is a mammal and a crested gecko is a reptile.

So, it is unfair to hold our memory and brain as a benchmark for measuring the memory and brain activity of crested geckos.

Now that we have cleared that, let us dive a little deeper into the biology of crested geckos.

In the earlier years, scientists had simply dismissed the notion that a crested gecko could undertake any complex cognitive activities.

But off late, studies have shown that the reptilian brain has a part called the medial cortex, which is similar in function to the hippocampus of the mammalian brain – the part that deals with memory.

So, it is clear that a crested gecko does have the biological capability to have memory – but the way its memory works is not through nostalgic recalling or remembrance.

It is more biological and need-based than emotional.

A crested gecko can:

  • Remember the female crested gecko it has tried to approach for mating
  • Recall the scent and voice of its owner and distinguish it from other humans
  • Remember spots that put it at high risk of being predated and spots where it is usually safe

As such, there has been no scientific study that dives deep into seeing and measuring the memory of crested geckos. But the observational evidence does suggest that crested geckos have memory.

Are Geckos Intelligent?

Yes, crested geckos are intelligent in terms of survival and primal biological needs. However, their intelligence manifests itself differently from conventional pets like cats and dogs.

The following are 10 cognitive abilities that are enough to classify a crested gecko as intelligent:

  1. Communication
  2. Consciousness
  3. Decision making
  4. Inquisitiveness
  5. Memory
  6. Sensory discrimination
  7. Social cognition
  8. Spatial cognition
  9. Visual cognition
  10. Time recognition

Can Crested Geckos Learn Tricks?

Unlike cats and dogs, it is almost impossible to teach your crested geckos any kind of tricks. However, you can get them to do simple things like jumping from one branch to another by offering food.

Moreover, if you say their name whenever you feed them, they will learn to associate the sound of their name with food. And that way, you can in a way get them to learn their name – so they will respond whenever you call their name.

How To Cater To Your Intelligent Crested Gecko

Intelligence – whether the mammalian kind that a human baby would show or the reptilian kind that a crested gecko shows – needs to be catered to and cared for.

The more you nurture and enrich it, the longer your crested gecko will remain intelligent with its growing age. Here are a few ways in which you can cater to the intelligence of your crested gecko:

  1. Offer a large cage that gives them plenty of space to move around and play. This will keep them mentally and physically active.
  2. Consider a terrarium or any other enclosure that has a bioactive environment. It will mimic the natural wilderness for your pet crested gecko, thereby keeping its instincts active.
  3. Give them a good, balanced diet that has all nutrients required by your crested gecko in the required amount.


Intelligence and memory in crested geckos are different from what we see in human beings – and that’s understandable considering how crested geckos have the reptilian biology in their brain, while we have a mammalian one.

But just because your crested gecko cannot do the things you can, it does not mean that your crested gecko lacks intelligence.

The intelligence, smartness, and memory of crested geckos, and other reptiles for that matter, are seen through their cognitive abilities – which indicate that crested geckos are smart.
