‼️Never run from a shark

When people get scared in the water, the first reaction is often swimming away as fast as possible, kicking hard, splashing, trying to get as far away as you can.
But in the ocean, this can work the opposite way than we think.

🦈Many predators react to fast, chaotic movement as a signal of prey. If you panic and try to escape quickly, you may look exactly like an injured or fleeing animal.
With sharks it’s important to stay calm, avoid sudden movements, and never turn your back to the animal.

When you lose sight of the shark, you also lose awareness of where it is. Most approaches in nature happen from behind or from the side.

💡So what should you do instead?

✔ stay calm and move slowly
✔ keep the shark in your field of view
✔ don’t swim away, hold your ground, and slowly back away toward a boat, reef, or group

The ocean is not our natural environment. We are visitors there.

Respecting its rules is the best way to move through it safely.

🌊 Do you know what could help the ocean?
Oysters.

It may sound surprising, but oysters are among the most sustainable seafoods we know today.

✔️They don’t need to be fed.
✔️They don’t need antibiotics.
✔️They don’t require catching other fish to produce food for them.

💡A single oyster can filter dozens of liters of water every day, helping improve the quality of coastal ecosystems. That’s why they are often called “ecosystem engineers” of the ocean.

🫴🏽 There’s also another interesting question: ethics.

Oysters have a nervous system, but they do not have a centralized brain like fish or mammals. To this day, the scientific community has no clear evidence that they consciously experience pain. For this reason, bivalves are often considered one of the least ethically problematic groups of marine animals, although with caution and without absolute claims.

➡️ But their importance can go even further.

In many coastal communities, traditional fishing is becoming less predictable as a source of income. And if we want to protect the ocean and sharks in the long term, simply banning fishing is not enough. We need alternatives that work for people too.

🔬That’s one of the reasons why oyster farming is part of our Amoara project in San Blas, Mexico.

This region has been identified by research as a nursery area for several shark species. At the same time, a large share of local catches consists of juvenile sharks that never reach reproductive age.

Oyster farms can offer a stable alternative to fishing, support local communities, and reduce the pressure on shark populations.

Sometimes ocean conservation doesn’t start with a ban. It starts with a new opportunity.💫

🦈 Meet Your Shark

To love the ocean means to respect it and understand it. That’s why we continue our series “Meet Your Shark.” Today: the Blue shark 🦈🩵

📍 Where can you find them?
In the open ocean of temperate and tropical regions almost worldwide. The blue shark is a pelagic species that spends most of its life far from the coast.

It has a long, slender body and usually grows to about 2-3 meters. Its color ranges from deep to light blue with a white belly. This contrast provides excellent camouflage in the open ocean. With its long snout and narrow, pointed pectoral fins, the blue shark has a very elegant, almost “flying” appearance in the water.

💡Did you know?

Blue sharks have large eyes adapted for hunting in the open ocean. They help them detect movement and silhouettes even in low-light conditions.

Blue sharks are mostly solitary and travel enormous distances across the oceans during their lives. They are among the most migratory shark species. Their diet consists mainly of cephalopods and pelagic fish, such as herring.

🤿🦈 Behavior and interactions

The blue shark is a medium-sized oceanic predator. Although it often appears calm and curious, it is still a wild animal that should always be treated with respect.
During encounters in the open ocean, blue sharks are often curious and may approach swimmers or divers to take a closer look. Sometimes they even pause directly in front of a person for a moment, observing.

Larger individuals can appear very confident, even around other sharks. They generally do not show aggressive behavior, but responsible behavior in the water is always essential.

Swimming with blue sharks is safest with experienced guides, who know how to manage the interaction and gently redirect the shark if necessary.

⚠️ This species is classified as Near Threatened.
The main threats are overfishing and bycatch in industrial fisheries.

🌊 March 22: World Water Day

💧Almost all the water we have on Earth eventually ends up in the ocean. But so do the chemicals we flush away, microplastics from our clothes, residues of medications, fertilizers from fields. Wastewater treatment plants cannot fully remove them. Rivers carry them onward. And the ocean becomes the final destination.🌊

This is where it begins to affect sharks.🦈

Sharks sit at the top of the food chain. That means everything their prey has accumulated eventually accumulates in them: heavy metals, persistent chemicals, microplastics. They are a biological mirror of the ocean’s condition. If the water is contaminated, we will see it in them first.

But water is not only about pollution. It is also about balance.💫

Climate change is altering ocean temperature, but also salinity. Melting glaciers and extreme rainfall decrease salinity in some regions, while faster evaporation increases it elsewhere. Salinity affects water density, ocean circulation, and species migration. Sharks respond sensitively to these changes. They shift migration routes, change depth ranges, and move toward more stable waters.

What we do on land reshapes their world.

World Water Day is not just a symbolic date. It is a reminder that there is no boundary between your bathroom, a river, and a shark in the ocean.

Turn off the tap. Do not let water run unnecessarily. Use washing machine filters that capture microfibers. Avoid cosmetics and cleaning products with microplastics. Reduce the chemical load we send down the drain. Every small decision remains within the system.

💫It is one water cycle. And we are part of it. In fact, we are largely “just” water ourselves. The human body is made of about 60% water. So when we speak about water as a system that connects us to the ocean, it is not a metaphor. 💧

🦈 Meet Your Shark

To love means to respect and to understand. That’s why we’re launching a new series: “Meet Your Shark.” If you already have a favorite one, tell us in the comments 🙂
Meet the Caribbean reef shark 🦈

📍 Where can you find it?

The Caribbean Sea and the western Atlantic:
Bahamas, Cuba, Mexico (Cozumel), Belize, Honduras, the Florida Keys, and the northern coast of South America.

It has a gray-brown body with a pale yellow to white underside, a short rounded snout, and large round eyes protected by a nictitating membrane. Most individuals divers encounter measure around 1.6 meters (5 ft). An elegant, steady swimmer moving confidently above the reef.

You’ll often find it near healthy coral reefs, along reef drop-offs, and in areas with mild currents. It typically inhabits depths of 5 to 40 meters, though it can go deeper.

🌊 👀 Behavior & interactions

Like many mid-sized reef sharks, the Caribbean reef shark generally pays little attention to divers. It approaches only if food is present. These are calm, smoothly swimming sharks that are not afraid of people.

🤿 During regular diving, they mostly ignore humans.

They respond more to:
– sudden, erratic movements
– distressed fish
– divers holding bait

In areas where shark feeding takes place, they may behave more boldly and approach more frequently. Not because they seek out people, but because they associate divers with food.

And what if you encounter one as an inexperienced snorkeler? Stay calm. The most likely scenario is that it notices you, assesses the situation, and calmly swims away.

They hunt primarily at night. During the day, you’ll often see them cruising peacefully above the reef or resting in gentle currents.

⚠️ This species is classified as Near Threatened.
Overfishing and coral reef degradation - the destruction of its home - are its main threats.

🦈 Safe swimming in the ocean 🌊

A few weeks ago, Australia experienced several shark incidents following heavy rainfall and murky water conditions around Sydney.

After strong rain, runoff carries nutrients into the ocean. This attracts schools of fish — which in turn attract sharks. Combined with reduced visibility, it creates what we call a perfect storm of shark conditions.

So why does visibility change everything?

🌊 Clear water = better awareness for both swimmers and sharks.

When the water is transparent, sharks can clearly identify that you are not their natural prey. And you can better assess what’s happening around you.

👀 What you can’t see, others can’t see either.
Shark incidents are not about sharks hunting humans. They are usually cases of mistaken identity influenced by multiple environmental factors.

Many incidents occur:
- In murky water
- Near river mouths
- After storms
- During strong wave action
- At sunrise or sunset

When visibility drops, contrast disappears. Identification becomes harder for everyone.

Even , who has worked with sharks for over 12 years, does not swim in shark-prone areas without good visibility.

👉 Her rule is simple:
“If you’re entering the ocean where sharks may be present, always wear a mask or at least swimming goggles. You need to know what’s happening below and around you.
If visibility is poor — don’t swim.
I personally never swim in the ocean with my head only above water. I always need to know what’s beneath me.”

🧠 Tips for safer swimming:

• Avoid swimming in murky water, especially after heavy rain or near river mouths.
• Avoid entering the water at dawn or dusk, when light levels are low.
• Swim in groups and in designated areas.
• Avoid shiny jewelry and high-contrast items that may create unusual reflections.

Sharks play a vital role in ocean ecosystems. They do not seek encounters with humans — we are not part of their natural diet.

But when visibility is reduced, a surfboard silhouette, a moving foot, a flash of reflection, or erratic movement can resemble prey.

Let’s remember:
We are visitors in the ocean.

What do you think came first on Earth?

🦈 sharks or 🌳 trees?

Sharks!

They appeared more than 450 million years ago.
Trees came tens of millions of years later.

When the first forests were only beginning to grow, sharks were already swimming through ancient oceans.

Over that time, sharks survived:

🌋 mass extinctions
🦕 dinosaurs (they came and went)
❄️ ice ages
🌍 the breakup of continents

Almost unchanged. Efficient. Precise.
An evolutionary design that still works today.
And then humans arrived.

In just a few decades, we caused what nature could not do in hundreds of millions of years.

Devastating losses. Population collapses. A real risk of extinction.

That is why we must protect sharks.
Not tomorrow. Today. Actually… yesterday.

Because if we lose sharks, we lose the balance of the ocean.

And without healthy oceans, we will not survive either.

Shark black eyes: a look into the abyss? 🕳️

🦈 Shark eyes are adapted for hunting in the depths, where light is often extremely limited.
They contain a high amount of pigment in the iris, which makes their eyes appear black. This helps them absorb more light and improves vision in dim or dark conditions.

⚫️ Night-vision mode: tapetum lucidum

Sharks have a reflective layer in their eyes called tapetum lucidum, similar to cats. It reflects light back through the retina, allowing sharks to see much better in low-light environments. In simple terms, they have a form of natural night vision.

👁️ Do shark eye colors change?

Although most sharks appear to have jet-black eyes, their irises can actually show subtle shades of blue, brown, or gray. This depends on lighting conditions and the species.
For example, great white sharks have a clearly visible iris, while species like mako sharks or tiger sharks often have eyes that appear almost completely black.

✨ Shark black eyes are not a sign of an “empty predator’s soul,” but a perfectly evolved adaptation for life and hunting in waters where humans can barely see their own hands.

🔬 International Day of Women and Girls in Science

In the first half of the 20th century, women were not allowed on research vessels. They could not dive, lead expeditions, or sign scientific papers. If they wanted to study the ocean, they had to create their own paths.

Pioneers like Rachel Carson were already shaping our understanding of the ocean as a living, interconnected system in the mid-20th century. Eugenie Clark, the “Shark Lady,” changed how the world saw sharks, proving they are not mindless monsters. Sylvia Earle later descended to depths no woman had reached before and went on to launch Mission Blue and the Hope Spots, protecting the most vital places in the ocean. And when Jasmin Graham saw how many voices were excluded from science, she co-founded MISS to open shark science to women and underrepresented groups.

Women were never late to ocean science. They were there from the beginning. Today, they stand at its core.

Today, women:
🦈 map shark migrations
📊 build global databases on species decline
🌍 push for protective legislation
👩‍🔬 work with communities and train the next generation of scientists

At Blue Religion, we carry this legacy forward every day. Our work is driven by Lucia, with over 12 years of experience in the field, alongside the scientific expertise of marine biologist Sabina, and Leticia, who assists our data analysis at SIRBAA.

Together, we are mentoring a new generation: the young women of CETMAR 26 and the AMOARA project. By bringing girls from local schools into the heart of our research, we aren’t just teaching science - we are showing them that a future in the abyss belongs to them, too.

Women in science were never missing.
What was missing was space, trust, and the power to decide.
The determination was always there.
Today their voices are heard - and the results speak for themselves.

Happy . Thank you 💙

Shark skin: armor from outer space? Kind of, yes. 👌

🦷🦈 Everyone talks about shark teeth. But did you know their skin is just as wild?

Its unique properties are so advanced that even engineers and tech developers study them. And yes… we’re actually back to teeth again.

🦈 Shark skin is covered with tiny, tooth-like scales called dermal denticles.

These denticles give the skin its rough texture and help reduce drag as sharks swim. The result? Greater hydrodynamic efficiency and speed. It’s a natural design perfected for fast, energy-efficient movement through water.

💡 Denticles also act as protection.
Their shape and structure prevent parasites, algae, and other organisms from attaching to the shark’s body, lowering the risk of infection and injury. At the same time, they form a kind of natural “armor” that helps protect sharks during hunting and encounters with other animals.

🪐 Shark skin is so effective that scientists and engineers use it as inspiration for modern technology.
In aviation and marine industries, shark-skin-inspired surfaces are being developed to reduce drag and improve fuel efficiency. In medicine, similar textures are used to create antibacterial surfaces that limit the growth of harmful bacteria in hospitals.
Nature really did the research first.
