US EditionLargest great white shark recorded in Atlantic resurfaces off Canadian coast
Contender, weighing 1,653 pounds, feeds on seals in northern waters to build fat for winter migration while researchers track its movements to identify possible mating sites.
- Contender, a 14-foot, 1,653-pound male great white shark tagged by OCEARCH in January, resurfaced near Canada's Labrador Peninsula in early October 2025.
- Researchers attribute Contender's northern migration to abundant prey, especially seals, which the shark relies on to build energy reserves before winter.
- Contender is estimated to be about 30 to 35 years old, with scientists noting this is one of the furthest northern tracking events they have observed.
- Fischer emphasized that studying large, fully grown male sharks is crucial for learning about the timing and locations of their mating behavior.
- OCEARCH scientists hope long-term tracking data from Contender, whose satellite tag will last five years, could reveal key white shark migration or breeding sites.
