Scientists dropped a cow into the South China Sea to study deep-sea life. What they found—rare sharks, polite feeding, and hidden biodiversity—was astonishing.

A record-breaking 60-foot fish has been spotted in the Pacific Ocean, sparking a wave of excitement and new questions about the ocean’s hidden giants.

The sight of a whale shark, the largest fish alive today, leaves most people humbled. Its slow, graceful movements and gentle nature often make them symbols of the ocean’s mystery. Yet behind this serene image lies a struggle for survival.

A new study of the mysterious Greenland shark has revealed the likelihood that specimens are born in the deep mid-Atlantic and then move closer to Europe as they enter their teenage years. Their favourite hang-out and feeding spot at this stage appears to be the Skagerrak strait between Denmark, Norway and Sweden.

In July 1970, a fisherman caught an unfamiliar shark in Papua New Guinea’s Astrolabe Bay. The mysterious creature—a pregnant female—had large, wide eyes, a big head and a short mouth. It also had a prominent, elongated fin protruding from its back, similar in appearance to a sail on a sailboat. Researchers later identified the animal as a new genus and species: the sailback houndshark (Gogolia filewoodi).

However, after that initial sighting, scientists never saw another sailback houndshark. That is, until now—more than 50 years later, the elusive creature has turned up again.

New research shows that baby blacktip reef sharks use warm waters to boost their escape performance from adult sharks, barracudas and other predators.

A 'shark' was walked through Galway to be displayed at the Spanish Arch to draw attention to the international gathering of scientists, researchers and shark enthusiasts from around the world this Friday in the city.

The study unveils a consistent seasonal gathering point for whale sharks, mostly juvenile males, in Wreck Bay, along the northern portion of the Great Barrier Reef. It’s the first known aggregation found in eastern Australia and in the entire southwest Pacific Ocean.

Off the coast of Tortuguero National Park in Costa Rica, a sport fishing trip in 121 feet (37 meters) of water led to a quite unusual find: a nurse shark glowing with an intense yellow-orange coloration. At roughly 6.6 ft (2 m) in length, the adult shark was an unmistakable outlier in a species known for its subdued coloration.

The highest accolade in this year’s competition, Shark Photographer of the Year 2025, has been awarded to Julian Hebenstreit for his stunning shot of an Indo-Pacific Leopard Shark (also known as a Zebra Shark) in Australia.
