Surfer, spear-fisher and free-diver Riley Elliott and marine biologist, shark diver and underwater photographer Kori Burkhardt put themselves in harm's way in don't-try-this-at-home "Shark Week" 2026 special "Secrets of the Great White Kill", and Live Science is here with all the TV and streaming details.

It doesn't always go to plan, as this seal uprising and vengeful turtle demonstrate, but great white sharks (Carcharodon carcharias) are known for attacking prey from below with such frightening speed and power it can propel their enormous bodies clear out of the water and stun or even kill their prey upon impact.

However, closer inspection has revealed that they can be a little more subtle when the need arises

In "Secrets of the Great White Kill," Eliott and Burkhardt aim to capture and unpack the full range of great white hunting techniques, including one or two surprising methods, the nuances of which have never been fully appreciated before.

Whale sharks may be the biggest fish in the ocean, but their feeding habits have remained mysterious. Now, new camera footage from the backs of these gentle giants has captured them doing something scientists rarely get to see: hunting for food far below the surface.

The footage reveals that whale sharks (Rhincodon typus) spend far more time feeding underwater than scientists realized and that they use a surprising variety of foraging techniques that had never been documented before.

The videos show whale sharks filtering food while cruising through open water, gliding downward as they feed during dives, climbing back toward the surface with their mouths still open, and cruising just above the seafloor to feed. Slow, steady underwater feeding turned out to be one of the sharks' most common activities.

Philip Motta, a professor emeritus of biology at the University of South Florida who was not involved in the study, said the videos provide "very valuable" new information on the variability of whale shark feeding behaviors, which have been poorly documented to date.

Cameras reveal whale shark feeding

Before this study, whale sharks had been studied from boats, from planes and by divers swimming alongside them. But those methods shared a blind spot: They could only follow the sharks when they were near the surface.

Earlier research had hinted that whale sharks spend a lot of time feeding out of view, at varying depths. In a 2020 study, researchers estimated that whale sharks may forage at these depths for up to 20% of the day and feed at the surface for less than 1% of their time.

In the new study, scientists strapped cameras directly onto the whale sharks, offering a rare shark's-eye view beneath the waves.

They deployed camera tags on 10 whale sharks at Ningaloo Reef in Western Australia and gathered more than 22 hours of footage from the sharks' own perspective. They combined that footage with a review of 106 previously published studies to build the most comprehensive catalog of whale shark behavior to date. Ultimately, they cataloged 36 distinct behaviors ‪—‬ 12 were related to feeding, and of those, six had never been recorded before. The findings were published July 21 in the journal Marine Biology.

Whale sharks can grow to 60 feet (18 meters) in length. And yet, this enormous fish survives on tiny prey ‪—‬ like krill, fish eggs and plankton ‪—‬ in tropical waters that are notoriously poor in nutrients. The ability to switch between so many feeding techniques may help to explain the long-standing puzzle of how such a large species can survive in these nutrient-poor waters.

However, even with a shark's-eye view, the cameras captured only part of the story. Whale sharks are known to dive hundreds of feet below the surface, where sunlight disappears and conventional cameras can no longer record.

"The most important new discoveries could be what these gentle giants are doing when they perform really deep dives," Motta said.

"Expedition X: Atomic Sharks" – a "Shark Week" 2026 special – sees biologist Phil Torres and "Expedition X" host Heather Amaro explore the islands' waters, including Troy's Coral Head, to establish if nuclear fallout could be behind reports of sharks displaying unusual and highly aggressive behaviors.

The U.S. military detonated 67 nuclear bombs at Bikini Atoll and Enewetak Atoll over 12 years from 1946 to 1958, which inflicted catastrophic and irreversible harm on the local populace and environment. Cancer rates among residents increased significantly, and local produce was rendered unfit for consumption.

Half a century later, however, the Marshall Islands became the site of the world's largest shark sanctuary.

Great white sharks can launch themselves clear out of the ocean, but why they breach so dramatically remains one of marine biology's biggest mysteries. "Air Jaws: Red, White and Breach", premiering during "Shark Week" 2026, follows a team of filmmakers and scientists as they investigate the shark's behavior.

"Shark Week" is now in its 25th year, and to mark this milestone, Jeff Kurr and marine biologist Alison Towner head to the Californian coast, which has seen an unexpected surge of great whites (Carcharodon carcharias) breaching the surface.

With cinematographer Andy Casagrande in tow, "Air Jaws: Red, White and Breach" aims to capture this behavior in full glory, and to establish why breaching great whites have entered American waters.

Researchers have identified a new species of "walking shark," a rare group of small carpet sharks that use their fins to "walk" along shallow reefs.

A team of divers spotted the newfound shark, which they named Hemiscyllium dudgeonae, in the dark waters around the reefs of southeastern Papua New Guinea. Gliding along the rocks was a small, brown-spotted shark that they didn't recognize.

"I was so excited. … I didn't look very closely at the pattern and quickly caught it and took it back to the boat," Christine Dudgeon, a senior research fellow at the University of the Sunshine Coast in Australia, told Live Science in an email.

Dudgeon handed the shark to Jess Blakeway, a doctoral student and first author of a new study describing the shark. Blakeway "noticed that the shark had a different pattern to the one that we were looking for and called out to me: 'Chris, it's different.'"

The new shark is named the Dudgeon's walking shark after Dudgeon, in recognition of her 20 years of researching the Hemiscyllium genus.

The new find, described June 15 in the Journal of the Ocean Science Foundation, brings the number of known walking shark species to 10, each with their own unique body pattern.

"This discovery is exciting because a lot of new fishes, and in particular, new shark and ray species, tend to be deep sea, so finding something in very shallow [less than 3 feet, or 1 meter] of water is unusual and highlights that there is potentially a lot of biodiversity that we really don't know about," Dudgeon said.

Encountering a new species

The team had been searching for another walking shark species, called Michael's walking shark (Hemiscyllium michaeli), when they encountered the unusual shark.

"Michael's walking shark has leopard prints and Dudgeon's walking shark has small white dashes and brown dots all over its body," Dudgeon said. "But with only one specimen we were not sure if this was an anomaly or a true difference."

The researchers continued surveying nearby reefs, and within two days, they had located 11 additional Dudgeon's walking sharks across three sites. These included males and females, both juveniles and adults, with all displaying the distinctive body pattern. That consistency convinced the team that they were likely looking at an undescribed species.

Dudgeon and Blakeway used genetic data to test this hypothesis at their laboratory in Australia. By comparing DNA from the newly discovered sharks with genetic samples from the other nine walking shark species, they confirmed that the population represented a new species.

Walking on land

Walking sharks are notable for their unusual biology. Unlike larger, open-ocean shark species, walking sharks spend their lives near coral reefs. Their ability to "walk" across the seafloor using their pectoral and pelvic fins is particularly useful during low tide, when parts of the reef become isolated from deeper waters. "Walking" helps the animals remain active when oxygen levels drop so that they can continue hunting prey across reef flats.

Scientists think this ability evolved as a response to the challenging environment of tropical reef flats, where oxygen levels can shift dramatically as the tides rise and fall.

Studies indicate that some walking sharks can survive in low oxygen environments for hours, though more research is needed to understand how the sharks are able to do this, Dudgeon said.

So far, Dudgeon's walking shark has been documented at only three locations in Papua New Guinea. If future research confirms that the species has a highly restricted range, H. dudgeonae could be vulnerable to habitat degradation, climate change or overfishing.

Many walking shark species appear to stay close to the reefs where they were born, which limits their ability to recolonize damaged habitats. Species with small geographic ranges are often more susceptible to population declines because local disturbances can affect a larger portion of the total local population.

The discovery also shows how new shark species are still being found in regions that have received relatively little scientific attention. Dudgeon and her team plan to continue doing surveys in Papua New Guinea to study the new species in its home environment.

"I think many people are not aware of the wonderful diversity of sharks and their relatives, the rays, skates and chimeras," Dudgeon said. "Very few species are dangerous to humans and they are a wonderfully broad and eclectic group of animals. They continue to surprise and fascinate us."
