Two Sharks Traveled 4,000 Miles Together

White sharks aren’t known for forming pairs—but Simon and Jekyll are changing that.

These two apex predators swam in near-perfect sync for over 4,000 miles (~6,437 kilometers) up the Atlantic coast, after being tagged off the southeastern United States in December 2022. Moving almost in tandem and showing up in the same places at the same time, their synchronized journey is unlike anything researchers have seen before.
