The largest male great white shark ever recorded in the Atlantic has been tracked migrating thousands of miles along America’s coastline, demonstrating the incredible power and persistence of one of nature’s most formidable predators.
Story Highlights
- Contender, a 1,653-pound great white shark, is the largest male ever recorded in the Atlantic Ocean.
- The 13-foot apex predator has traveled from Florida to Canada and back in 2025.
- Recent tracking shows the shark off the New Jersey coast heading south for winter migration.
- OCEARCH scientists use satellite technology to study shark behavior and ocean ecosystems.
Record-Breaking Atlantic Predator Makes Headlines
Contender stands as a testament to the raw power of nature that thrives in American waters. Tagged by OCEARCH in January 2025 off the Florida-Georgia coastline, this massive great white shark weighs 1,653 pounds and measures 13 feet in length.
Scientists estimate the apex predator to be approximately 32 years old, making him a mature adult specimen. His size places him in the record books as the largest male great white shark ever documented in the Atlantic Ocean, showcasing the incredible biodiversity that exists in coastal American waters.
🦈 ON THE MOVE: Contender, the largest male white shark recorded in the Atlantic Ocean is on the move once again. He was pinged last night off the coast of Atlantic City, New Jersey. Where will he show up next? https://t.co/WDpu4hiSbf

Advanced Tracking Technology Reveals Migration Patterns
OCEARCH, a global nonprofit organization, uses sophisticated satellite tracking technology to monitor ocean giants and marine ecosystems. The tracking system requires Contender’s dorsal fin to break the water surface while an Argos satellite passes overhead to record his precise location.
This cutting-edge approach provides invaluable scientific data about shark behavior and migration patterns.
The organization’s mission focuses on collecting essential information to better understand marine species and ocean health, contributing to conservation efforts and scientific knowledge that benefits both wildlife and coastal communities.
Epic Journey From Florida to Canadian Waters
Contender’s migration demonstrates the remarkable range of great white sharks in Atlantic waters. From April to mid-June 2025, tracking data showed him frequenting the waters off North Carolina’s Outer Banks, including a June ping approximately 22 miles from Cape Hatteras.
He continued his northward journey in July, appearing off the Massachusetts coast before reaching his northernmost point near Pointe-Parent, Quebec, in late September.
This extensive migration pattern covers thousands of miles and multiple international waters, highlighting the interconnected nature of marine ecosystems along North America’s eastern seaboard.
Return Migration Signals Seasonal Behavior
The shark’s recent southward movement reflects natural seasonal migration patterns that have occurred for millennia. Between October 27-29, 2025, multiple pings tracked Contender moving south from Canadian waters back toward the United States during the fall migration season.
His November 11, 2025, appearance several miles off Atlantic City, New Jersey, marks his continued journey toward warmer waters.
Scientists believe he is heading back to Florida, where warmer temperatures and abundant food sources provide optimal conditions for the winter months, demonstrating the predictable yet remarkable nature of these apex predators.
