Recent satellite tracking of Contender, the largest adult male white shark tagged in the Atlantic, is shedding light on potential reasons behind the migration patterns of these majestic creatures. This significant research is spearheaded by OCEARCH, a renowned organization dedicated to studying marine life.
Contender was tagged in January 2025 along the Florida/Georgia coastline. Since that pivotal moment, his journeys have been meticulously recorded through satellite pings, allowing scientists to map his movements and migration routes throughout the year.
On Wednesday, April 1, Contender was tracked as he ventured beyond the Gulf Stream, far off the coast of Georgia. This latest location update provides valuable insights for researchers keen on understanding the behavior of white sharks.
According to OCEARCH scientists, Contender’s swift transition from the coastal waters of Florida to the expansive depths of the ocean might indicate a breeding activity. As these patterns unfold, they offer a glimpse into the intricate lives of white sharks and the environmental cues that drive their migrations.
OCEARCH scientists said his recent movements from near the coast of Florida to rapidly moving out into deeper waters could be a sign of breeding.
“This sudden movement could be to forage in deeper waters, but we cannot rule out the possibility that it’s related to reproduction at this time of year,” said OCEARCH Senior Data Scientist John Tyminski.
OCEARCH said these trends are common among mature male white sharks like Contender and Breton.
Since his tag on Wednesday, Contender has moved back closer to the Georgia coast, still in deeper waters, but just on the edge of the Gulf Stream.
Clocking in at nearly 14 feet long and roughly 1,650 pounds at the time of his tagging, Contender is OCEARCH’s largest male white shark ever tagged in the Atlantic.
His movements have taken him all around the East Coast of the US, and up into Canada.
OCEARCH is a global nonprofit organization dedicated to researching and protecting sharks, whales, sea turtles and other ocean life, tagging these animals to track and study their migration habits and behaviors from afar.
