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.
