THE ORANGE SHARK 🦈🧡

🕵️ A Curious Minds Discovery

Today we came across a picture that looked so strange we genuinely wondered...

IS THIS EVEN REAL?!

It showed a shark swimming through the ocean.

But this wasn't a normal grey or brown shark.

It was...

🧡 BRIGHT ORANGE!

At first glance, it looked edited.

Maybe someone had changed the colour of an ordinary shark.

Maybe it was AI.

Or maybe there really was an enormous orange shark swimming around somewhere in the ocean.

So, naturally, we had to investigate.

And amazingly...

IT IS REAL! 🤯🦈

The shark was discovered off the Caribbean coast of Costa Rica, near Tortuguero National Park.

It was a nurse shark, but it had one incredibly unusual feature.

Its entire body was a brilliant golden orange colour, and even its eyes were unusually pale.

Scientists had never documented a nurse shark quite like it before.

🦈 What Is a Nurse Shark?

Nurse sharks normally look VERY different from our orange friend.

They are usually shades of brown or greyish brown, which helps them blend into their surroundings.

They spend lots of time near the sea floor and search for animals such as fish, squid, crabs and other small sea creatures to eat.

But this particular nurse shark wasn't exactly winning any awards for camouflage.

Because...

Well...

IT WAS ORANGE. 😂

🧡 Why Was the Shark Orange?

Scientists believe the answer involves an extremely rare pigmentation condition called:

XANTHISM

Xanthism causes an animal to have unusually strong yellow, golden or orange colouring.

Pigments are substances that help give living things their colours.

Most nurse sharks have much darker colouring.

But in this shark, the usual colouring had changed dramatically, leaving it looking almost golden orange.

👀 But Look at Its Eyes...

This is where things become even stranger.

The shark didn't just have orange skin.

It also had extremely pale, almost white looking eyes.

Scientists believe this suggests that the shark may have a combination of xanthism and albinism.

Albinism affects the production of melanin, one of the pigments responsible for darker colouring.

Having signs of both conditions together is incredibly unusual.

Scientists described the shark's appearance as albino xanthochromism.

📏 This Wasn't a Baby Shark!

You might imagine that such an unusual shark was a tiny youngster.

Nope.

It measured approximately...

2 METRES LONG! 😳

That's around the height of a VERY tall adult human.

Its size showed researchers something particularly interesting.

This shark had managed to survive long enough to reach adulthood despite having such unusual colouring.

🥷 Camouflage? What Camouflage? 😂

Animal colouring isn't just about looking pretty.

For many animals, colour is an important survival tool.

A shark whose colouring blends into the sea floor may be harder for other animals to notice.

That can help it approach prey and can also make it less noticeable within its environment.

So imagine being a nurse shark...

Everyone else turns up wearing sensible shades of brown.

And you arrive looking like:

🧡🧡🧡 HELLOOOOOOO! 🧡🧡🧡

Scientists therefore found it particularly interesting that this incredibly noticeable shark had successfully survived into adulthood.

Its existence suggests that xanthism had not prevented this particular shark from surviving in the wild.

🎣 How Was It Discovered?

The story began during a sport fishing trip near Tortuguero National Park in Costa Rica in August 2024.

The shark was caught at a depth of around:

37 METRES

Imagine lowering yourself down the length of roughly three double decker buses standing upright.

That's approximately how far beneath the surface it was.

When the fishers saw the shark's extraordinary colouring, they took photographs.

Most importantly...

🦈 IT WAS RELEASED BACK INTO THE OCEAN. 🌊

Those photographs were later studied by scientists.

🔬 Then Scientists Made It Official

Although the shark was encountered in 2024, the scientific research describing it was published in 2025 in the journal Marine Biodiversity.

That's an important little science lesson in itself.

The date something is discovered isn't always the same as the date scientists publish their research about it.

Researchers need time to examine evidence, compare it with previous discoveries and prepare their findings for scientific publication.

So when we see a news story saying scientists have reported something incredible, the actual discovery may have happened months or even years earlier.

🌎 Why Was This Discovery So Special?

This wasn't simply an orange shark that looked cool.

Scientists reported it as the:

FIRST SCIENTIFICALLY DOCUMENTED CASE OF TOTAL XANTHISM IN A NURSE SHARK!

It was also the first recorded case of xanthism among the group of cartilaginous fishes, which includes sharks, rays and skates, in the Caribbean Sea.

That means one photograph of one extremely unusual shark added something new to our scientific knowledge of these animals.

Pretty amazing.

🤯 AMAZING GOLDEN SHARK FACTS

🦈 It is a nurse shark.

🧡 Its body has an extraordinary yellow orange colour.

👀 It has unusually pale white eyes.

🧬 Scientists believe it shows xanthism together with albinism.

📏 It measured approximately 2 metres long.

🌊 It was found near Tortuguero National Park in Costa Rica.

⬇️ It was caught at approximately 37 metres deep.

📅 It was encountered in August 2024.

🔬 The scientific research was published in 2025.

🌎 It became the first scientifically documented totally xanthic nurse shark.

🎣 After being photographed, the shark was released back into the ocean.

💭 CURIOUS MINDS QUESTION

Imagine you are an ocean scientist.

Someone sends you this photograph and says:

"I promise this shark really is orange!"

Would you immediately believe them?

Or would you investigate first?

What evidence would you want before deciding the photograph showed a real animal?

And here's another one...

Why do you think most sharks aren't brightly coloured like this one?

Think about camouflage, finding food and survival.

🌍 THE BEST PART OF TODAY'S DISCOVERY

We found this shark because we saw an extraordinary picture online and wondered whether it was real.

And that's actually a pretty important habit to have.

Not everything we see online is real.

Pictures can be edited.

Information can be wrong.

And now AI can create animals and photographs that look incredibly convincing.

But instead of immediately believing something...

or immediately deciding it must be fake...

WE CAN INVESTIGATE. 🔎

In this case, we followed the story back to actual scientific research.

And somehow the truth was even cooler than the picture.

There really is an enormous golden orange nurse shark that was discovered swimming in the Caribbean.

Scientists still don't know everything about why this particular shark developed its extraordinary colouring.

Which means there are still questions waiting to be answered.

And that might be our favourite thing about science.

The more we discover, the more there is to wonder about. 🌊🦈🧡
