The largest male great white shark ever seen in the Atlantic resurfaces after traveling 7,000 miles; scientists say his journey is far from over World News
The largest satellite-tagged male great white shark in the Atlantic has resurfaced off North Carolina’s Outer Banks, giving marine scientists another chance to learn about one of the ocean’s most dramatic migrations. The 14-foot-long, 1,700-pound shark known as “Contender” has traveled more than 7,000 miles since being tagged in 2025 before briefly triggering the satellite tag. Although the transit time was too short to determine its exact location, researchers believe it was continuing its annual journey to its northern feeding grounds.The latest detection also highlights how satellite tracking is helping scientists better understand the movement, habitat and long-term recovery of great white sharks, while placing Contender’s impressive size on display alongside Deep Blue, the world’s largest known great white shark.
Largest satellite-tagged male great white shark continues its Atlantic migration
When the latest update was released, the Contender’s satellite tag briefly emerged from the water, allowing it to communicate with orbiting satellites, before disappearing under the sea again. The signal transmission lasted only a few moments, and scientists were unable to determine the shark’s precise location.Even so, the detections were enough to suggest the animal was moving along the U.S. east coast. Marine biologists following the project believe the sharks are continuing the northward journey familiar to many adult great whites as summer approaches.Adult white sharks don’t stay in one place for long. As ocean temperatures change with the seasons, they regularly migrate between warmer southern waters and more fertile northern waters.The waters around Cape Cod and Atlantic Canada become attractive destinations in late spring and summer because they offer abundant prey and conditions suitable for the species. Gray seals, along with large schools of fish, form an important part of the diet in these areas.Closer to the northeastern coast of the United States, white sharks also feed on schools of herring that congregate near shorelines, including around Long Island. Tracking individual sharks helps scientists understand how these seasonal movements connect different parts of the Atlantic ecosystem.
A shark that has traveled thousands of miles
In January 2025, Contender installed satellite tags during a research expedition off the coast of Florida and Georgia, The Sun reported. At the time, the adult male was about 14 feet long and weighed nearly 1,700 pounds, making it the largest male great white shark ever tagged by researchers in the western North Atlantic.Since then, his documented route has stretched more than 7,000 miles. The shark traveled between the waters off Florida and Canada’s Gulf of St. Lawrence, reflecting the extraordinary distances adult great white sharks often travel during their lives.Tracking devices connected to the Contender are expected to continue sending data for several years, as long as the Contender surfaces long enough to connect with the satellite. Each successful transmission allowed researchers to record his movements in more detail.
Why scientists have been paying attention
Satellite-tagged sharks provide information that would otherwise be nearly impossible to collect. Their journey reveals where mature animals spend different times of the year, which habitats they rely on and how they respond to changing environmental conditions.Researchers also use these long-term records to improve understanding of breeding populations and recovery trends. Each new location contributes to a growing data set that can support future conservation efforts and improve understanding of one of the Atlantic’s most closely studied marine predators.
Why Deep Blue Is Still the Largest Great White Shark Ever Recorded
Although the “contender” is an unusually large male great white shark, he is not considered the largest great white shark known to science.This distinction is widely associated with Deep Blue, a famous female great white shark estimated to be about 20 feet long and weighing about 4,500 pounds. Deep Blue has been photographed and filmed in waters off Hawaii and has become one of the most easily identifiable individual sharks ever seen.This difference also reflects the biology of the species. Female great white sharks often grow much larger than male great white sharks, sometimes reaching sizes that few male great white sharks can match.
Tracking a species that still surrounds many mysteries
Great white sharks remain one of the most wide-ranging predators in the ocean, capable of traveling long distances throughout coastlines and even ocean basins. Despite decades of research, many aspects of their movement and behavior are still pieced together through satellite tracking projects.The contenders’ latest appearance near North Carolina adds another waypoint to a journey that’s far from over. Although the exact location where he surfaced remains unknown, the brief signal indicated that his seasonal migration was continuing just as scientists expected, providing another valuable insight into the life of one of the Atlantic’s most impressive marine animals.
