A voice for Sharks
“What Rob Stewart accomplished in this beautiful film is more than most people can accomplish in their entire lives.” ~ Hayden Panettiere
While Hayden Panettiere was best known for her roles in Heroes and Nashville, her life was marked by much more than her work on screen. She sadly passed away on August 16, 2026, at the age of 36, leaving behind a legacy of advocacy for the marine animals she cared so deeply about.

Panettiere became a fan and vocal advocate for Rob Stewart’s work following the release of Sharkwater in 2006, and the two became friends. She went on to become a Sharkwater Ambassador, supporting Stewart’s mission through the releases of Revolution and Sharkwater Extinction, as well as the launch of the Rob Stewart Sharkwater Foundation and the Shark Free movement. Leveraging her Hollywood platform to support the cause, she gave numerous interviews advocating for shark protection. In March 2020, Hayden was also set to join the M/V Sharkwater expedition to the British Virgin Islands to promote shark sanctuaries and support research in the BVI, but the expedition was ultimately cancelled because of the worldwide COVID-19 lockdown.
Hayden was fascinated by sharks, even describing herself as a “shark magnet” during an appearance on Jimmy Kimmel Live, joking about how sharks seemed to always find her whenever she was in the ocean. During an appearance on The Ellen DeGeneres Show, she also shared photos and stories from her encounters with hammerhead and nurse sharks, offering a glimpse into her personal connection with these animals.
Hayden Talks about Rob
Panettiere attended the star studded Hollywood premiere of Sharkwater Extinction with her brother and mother in January 2019. Speaking about the film, she said: “What Rob Stewart accomplished in this beautiful film is more than most people can accomplish in their entire lives.”
But sharks were far from the only ocean creatures Hayden fought to protect throughout her short but impactful career. Her commitment to marine conservation began with whales and dolphins at the heart of her early activism.
A Lifelong Fight for Cetaceans
2005: How it all started
Hayden’s journey into marine conservation goes all the way back to 2005, when she was approached by Jeff Pantukhoff, founder of The Whaleman Foundation, while filming Shanghai Kiss. Knowing of her deep love for animals, he showed her footage of the threats facing whales and dolphins and invited her to join his mission. Deeply affected by what she saw, Hayden agreed.
She would go on to become the International Spokesperson for The Whaleman Foundation and its Save the Whales Again! campaign, using her growing public platform to raise awareness about whaling, dolphin hunts, and the threats facing cetaceans.
2007: Her Activism in Taiji
By 2007, Hayden was taking her activism beyond awareness campaigns and into direct action. In October of that year, at just 18 years old, she travelled to Taiji, Japan, alongside five other activists and surfers to protest the annual dolphin hunts.
The group paddled into the cove and attempted to intervene as pilot whales were being driven toward shore. What began as a peaceful protest quickly became a violent confrontation, as fishermen used boat propellers and poles to force the protesters back. The group eventually had to retreat and leave Japan, reportedly facing an arrest warrant for their actions.
The confrontation made international headlines, and footage from the protest was later featured in The Cove, the documentary that exposed the Taiji dolphin hunts to audiences around the world.
2009–2011: Beyond Taiji
Following the international attention The Cove brought to the dolphin hunts, Hayden returned to Japan with Jeff Pantukhoff, this time hoping to raise awareness and open a dialogue with people and officials in Taiji. During this trip, she met with Japanese political and business leaders in Tokyo to discuss ways to work together.
Her advocacy soon reached beyond Japan as well. By 2011, Panettiere had brought her voice to Washington, where she met with members of the Obama administration to discuss the protection of whales, oceans, and marine life.
Taiji was only one chapter in a much longer commitment to marine conservation. In the years that followed, Hayden continued to use her voice and public platform to advocate for sharks, whales, dolphins, and the protection of our oceans.

Hayden Panettiere spent years turning her love of marine life into action. Her activism took her from the waters of Taiji to Washington,to Rob Stewart’s mission to protect sharks. Her legacy lives on through the causes she supported, the awareness she raised, and the people she inspired to speak up for our oceans.
