A 14-foot, roughly 1,700-pound male great white named Contender—the largest male white shark tagged in the western North Atlantic—has been detected off North Carolina’s Outer Banks and is likely migrating north toward Cape Cod, underscoring ongoing East Coast tracking of great whites; Deep Blue remains the largest-known great white at about 20 feet and 4,500 pounds.
Ripple, a subadult male great white shark tagged off Nova Scotia in Sept 2025, logged a 354-mile sprint along the East Coast in the past week and is now about 45 miles off Cape Breton, the farthest north Ripple has been tracked. Having traveled more than 8,000 miles since tagging, Ripple could continue northeast toward Newfoundland or northwest into the Gulf of St. Lawrence as it follows cooler waters and prey, with real-time updates available via the OCEARCH Global Shark Tracker app.
The Atlantic’s largest tagged male great white shark, Contender, appears to be migrating toward Cape Cod after a roughly 7,000-mile journey in the North Atlantic; a July 10 Z-ping showed movement from the Outer Banks, with Cape Cod offering warm water and plentiful prey as a migration hotspot in summer and fall. Beachgoers should stay alert, swim near lifeguards, avoid dusk and dawn, and follow posted advisories as the shark continues its seasonal movement.
A 1,653‑pound, nearly 14‑foot great white shark named Contender resurfaced off North Carolina’s Outer Banks and appears to be migrating north toward Cape Cod and eastern Canada, tracked in near real time by the OCEARCH shark tracker.
The Atlantic’s largest tagged great white, Contender—about 14 feet long, 1,653 pounds, and a ~30-year-old male—surfaced off North Carolina’s Outer Banks, as it continues a northward migration toward Cape Cod and eastern Canada per OCEARCH. Tagged Jan. 17, 2025 off the Florida–Georgia coast, Contender has pinged multiple times, with a July 10 surface sighting marking its ongoing movement in search of warmer waters and prey.
Shark Tracker, powered by OCEARCH, is a free app that allows users to track sharks and other marine life, providing insights into their movements and behaviors. The app displays the recent locations of tagged sharks and other sea creatures, offering a wholesome alternative to doom scrolling and fostering a sense of connection to the ocean. Users can follow individual sharks, receive notifications when they surface, and explore the vast distances these creatures travel, ultimately promoting awareness and conservation efforts for marine life.
A massive 1,400-pound great white shark named Breton, who has been tracked by OCEARCH since 2020, was spotted off the Florida coast near Daytona Beach after a 34,000-mile journey. Initially tagged in Nova Scotia, Breton's appearance coincides with the annual migration of various shark species to warmer waters during the winter months. This event highlights the migratory patterns of sharks in response to ocean temperature changes, with Breton and other sharks like Penny, a 522-pound juvenile, being monitored as they travel to Florida's coasts and the Gulf of Mexico.
OCEARCH, a marine research organization, has tracked the movement of a massive 1,700-pound great white shark named Mahone off the coast of Georgia. Mahone was initially tagged in October 2020 near Lunenburg, Nova Scotia, and has since traveled over 17,800 miles. OCEARCH's current expedition aims to learn more about white sharks as they migrate to the southeast United States for winter residency and understand their reproductive cycle. The organization has successfully tagged 92 white sharks in the western North Atlantic and aims to reach a goal of 100 sharks sampled, tagged, and released.
Two great white sharks, named Simon and Jekyll, have surprised experts by becoming travel companions and swimming together for about 4,000 miles from the Georgia coast to Nova Scotia. This unusual behavior challenges the belief that great whites are solitary creatures. OCEARCH scientists are testing DNA samples to determine if the sharks are biological brothers or half-brothers. The discovery is considered groundbreaking and could provide new insights into shark behavior and conservation efforts.
Researchers at OCEARCH were surprised to discover that two great white sharks, named Simon and Jekyll, have become friends and traveled over 4,000 miles together up the Atlantic Coast. Great white sharks are typically solitary creatures, so this unusual companionship is groundbreaking. OCEARCH plans to conduct genetic analyses to determine if the sharks are related.
Researchers were surprised to discover that two great white sharks, Simon and Jekyll, had become friends and traveled over 4,000 miles together up the Atlantic Coast. This finding is unexpected as great white sharks are typically solitary creatures. Ocearch, the nonprofit research organization, plans to conduct genetic analyses to determine if the sharks are related. While some shark species form social groups, great white sharks are known for their solitary existence, making this discovery potentially groundbreaking.
Two great white sharks, named Simon and Jekyll, have surprised researchers by traveling together for thousands of miles along the Atlantic coast. This discovery challenges the belief that great white sharks are solitary creatures. The nonprofit research organization OCEARCH, which tagged the sharks, is now analyzing blood samples to determine if the sharks are related. The development is considered potentially groundbreaking and sheds new light on the behavior of these apex predators.
Researchers from Ocearch have observed a significant increase in the number of great white sharks off the East Coast of the US, with the ocean teeming with life like it hasn't since the 1940s or 50s. Ocearch has been studying and tagging great white sharks for the last decade, tracking their migration patterns online. The team has studied over 90 great white sharks, collecting samples for 24 different scientific studies, including one that would test the shark's hormone levels to discern whether she was mating. A healthy shark population is better for the entire planet, says chief scientist Dr. Bob Heuter.
A 12-foot, 4-inch great white shark named Ironbound, tagged by OCEARCH in Nova Scotia in 2019, has been spotted off the coast of South Carolina after disappearing from tracking in April 2022. Ironbound has swum over 15,186 miles since being tagged and is part of the annual migration of great white sharks in the Atlantic Ocean. OCEARCH has been tagging great whites for over a decade to collect data on their life-cycle and takes biological samples before releasing them back into the ocean.
Scientists from OCEARCH are on a mission to discover where great white sharks mate in the Atlantic Ocean, a mystery that has puzzled researchers for centuries. The team hopes to find out by taking blood samples from sharks off the coast of the Carolinas during their summer migration. The great white shark population has been decreasing due to overfishing, pollution, and habitat loss, making conservation efforts crucial to protect these apex predators and their critical role in ocean ecosystems.
