Sei Whales Can Reach Highway Speeds That Rival Fast Ships

The species name borealis means northern, reflecting the whale's frequent presence in northern hemisphere waters.

This speed allows sei whales to cover vast oceanic distances in search of plankton-rich waters, helping them adapt to shifting prey patterns across temperate and subpolar seas.

Their streamlined bodies and powerful tail flukes demonstrate how evolution balances immense size with hydrodynamic efficiency in the open ocean.
