How to Track Contender, the 1,700-Pound Great White Shark Heading to Cape Cod

Contender is currently the largest male great white shark tagged in the western North Atlantic. Weighing nearly 1,700 pounds and measuring over 13 feet, this shark is a focal point for researchers studying migration patterns along the coast. Recent satellite pings place him off the Outer Banks of North Carolina as he completes his annual trip toward the waters of Cape Cod.

Researchers from OCEARCH tagged the 30-year-old shark back in early 2025 off the coast of Florida. The tag on his dorsal fin transmits data when he surfaces, which allows the team to track his movements over his expected five-year battery life. This data contributes to a broader scientific understanding of how these apex predators move between the southeastern United States and Atlantic Canada to find food sources like grey seals.

While his size is notable, experts clarify that he is not the largest shark on record. Large females such as Deep Blue often reach weights significantly higher than Contender. The focus remains on his migration habits rather than his status as a record holder.

Beachgoers often express concern when large sharks are tracked near the coastline. However, there are no documented instances of Contender interacting with humans in a harmful way. Scientists note that these animals are simply moving through their natural habitat in search of seasonal prey. Staying informed about local safety advisories near feeding grounds remains the standard procedure for those in the water.

Those interested in the raw data can view his movements via the public tracking tools provided by researchers. This level of transparency helps the public understand the behavior of great whites and supports ongoing conservation work for the species. Watching his path offers a direct look at the travel patterns that define the life cycle of these large marine predators.
