Largest Male Great White on Atlantic Record Pings Off Northeast Florida

Researchers are tracking the mature shark’s early-spring movements for clues to where great whites mate.

Overview

  • OCEARCH reports multiple recent pings along Florida’s Atlantic coast, most recently Thursday afternoon just north of Jacksonville.
  • The shark, nicknamed Contender, also pinged about six miles off St. Augustine on March 12 after a southbound trek.
  • Contender measures roughly 14 feet and around 1,700 pounds and is described by OCEARCH as the largest mature male they have tagged.
  • Tagged near the FloridaGeorgia border in January 2025, he migrated to Canada’s Gulf of St. Lawrence in summer before returning south.
  • Scientists are increasing monitoring as his coastal proximity and the late winter to early spring window may align with mating activity, with no mating events or public-safety incidents reported.
