Red Sea Creatures Podcast

Parties to the UN desertification convention chose Egypt unanimously to host COP18 in 2028. The convention deals with soil, not water, but dust from degraded land falls on the Red Sea and measurably changes what happens there.

Discover the ocean's most surprising partnerships, where species like a burrow-digging shrimp and its fish lookout depend on each other without trust. From a nearly blind shrimp guiding itself by a goby's tail to cleaner shrimp tending to giant predators, these remarkable symbiotic relationships are driven by specific, intricate mechanisms rather than simple goodwill.

Discover the "Great Cerulean Deception": the vibrant blue of our oceans and many animals isn't due to paint or pigment, but a fascinating trick of physics. Water absorbs most light, scattering only blue back to our eyes, while creatures utilize intricate structures to precisely reflect blue wavelengths. This structural color means blue is often a property of light itself, not a built-in hue.

A crab named after a Roman boxing glove, an anemone named after a night demon, an urchin whose name simply says "of the red sea". Scientific names look arbitrary until you learn that nobody approves them: a name is staked like a mining claim, anchored to one specimen in a museum jar, and settled by whoever published first. Here is how the system works, and why the name you learned keeps changing.

High above the New South Wales coast, drone pilot Alexander Forrest witnessed a truly extraordinary event: the birth of a humpback whale. This marks only the fourth time a humpback birth has ever been filmed, and significantly, the first captured by a drone. This technological milestone provided an intimate, undisturbed view of a multi-tonne giant in her most vulnerable state.

Imagine a creature smart enough to solve puzzles and recognize faces, yet whose entire existence unfolds in less time than it takes to pick a movie. This is the octopus: an animal whose every move, from open ocean drifts to hidden den sanctuaries, is a finely tuned race towards one single, unrepeatable reproductive moment – a life of profound intelligence lived on an extraordinary deadline.

Decades of sensationalism have misrepresented sharks as mindless killers, overshadowing their critical role in ocean health. These ancient apex predators are vital architects of the food web, maintaining ecological balance and proving overwhelmingly harmless to humans. Shark Awareness Day pushes back against the myth, inviting us to see these magnificent creatures not as villains, but as essential guardians of the deep.

Your first boat dive comes with an alphabet soup of NDLs, SMBs and buddy checks that sounds like a secret code. It kind of is - every acronym is a small safety ritual packed into a few letters. Here are the nine that matter most, decoded in the order you meet them on a real dive.

A field guide, a dive planner, and a love letter to one of the richest seas on Earth - now an app. Here's everything it can do, and why I built it.

While we often picture sharks as apex predators, a newly discovered species in Papua New Guinea challenges this notion by literally "walking" across the seabed on its fins. This unique shark, Hemiscyllium dugeonae, uses its fins like limbs and even boasts a "decoy eye" to fool predators, showcasing an unhurried and localized lifestyle far removed from the typical high-speed chase.

Sea turtles have swum Earth's oceans for an incredible 150 million years, outlasting dinosaurs and every major global catastrophe. On World Sea Turtle Day, June 16th, we celebrate these ancient survivors but also face a harsh truth: human civilization now poses a unique threat they can't adapt to, with six of the seven species fighting for their lives.

Every dive you take, every photo you snap, can become a vital part of global ocean conservation. Turn your passion into purpose by contributing real-time data and observations - no PhD needed - to fill critical knowledge gaps and protect our seas.

Today marks the birthday of Jacques-Yves Cousteau, a visionary who revolutionized ocean exploration and changed how humanity sees the sea. Despite a career-ending accident, he gave the deep a voice, bringing its wonders into homes worldwide and making his pioneering work more relevant than ever.

Imagine a world where your safety depends on remembering every past interaction with others. Female bottlenose dolphins navigate just such a complex social landscape, using sophisticated long-term memory to track the behavioral history of males and protect themselves in a way we're only beginning to understand.

Every year from June 8-16, Sea Turtle Week calls on us to celebrate and act on behalf of these extraordinary ancient mariners. Having outlasted dinosaurs and ice ages, all seven species now face their greatest test, urgently needing our active protection from modern threats.

The ocean is our planet's primary life-support system, generating over 70% of the oxygen we breathe and buffering our climate from excess heat and carbon. This World Oceans Day marks a crucial transition from passive inheritors to active guardians, urging us to reimagine our relationship with the sea to protect it from escalating threats like warming and acidification.

Beyond their whimsical charm, seahorses are nature's most audacious biological chimeras, defying traditional definitions of fish. They are living mosaics of evolutionary innovations, "plagiarizing" traits from across the animal kingdom, most notably with males undergoing a radical hormonal alchemy to carry and nurture their young in a unique brood pouch. This reveals profound rule-breaking and efficiency in nature's designs.

Egypt’s Red Sea diving scene is entering a new era in 2026, with stronger regulation, greater environmental focus, and a push for more transparent, professional dive operations. From Hurghada and Sharm El Sheikh to Dahab and Marsa Alam, divers can expect a better-protected reef experience as the industry shifts from volume-driven tourism to reef stewardship.

Along the Welsh coast, a peaceful morning walk has turned into a disturbing discovery as dog walkers found hundreds of dead catsharks and fish washed ashore. The scale and concentration of the wash-up suggest something far more serious than a routine strandings, raising fears of an industrial fishing incident just offshore.

A rare “ghost shark” has been rediscovered thriving in a remote Indonesian river, overturning assumptions that the Ganges shark was nearly gone. The finding of 43 specimens in North Kalimantan suggests the species may be far more resilient - and far more overlooked - than scientists once believed.
