Scubaism

In one report, appearing in the journal Hydrobiologia, a team of international scientists documented two giant bluefins tagged within minutes of each other off the coast of Ireland. The two fish swam to opposite sides of the Atlantic Ocean—ending up more than 3,000 miles (5,000 kilometers) apart.

One of the fish traveled 3,730 miles (6,000 kilometers) southwest to waters about 186 miles (300 kilometers) northeast of Cuba. The other remained in the eastern Atlantic and moved off the coasts of Portugal.
