Commercial Whaling Pushed Sei Whales to the Brink in the 20th Century

Sei whales were often called the last great whale to be intensively hunted during commercial whaling.

The sharp population decline disrupted marine ecosystems and revealed how quickly even large, wide-ranging species can be depleted by industrial exploitation.

International protection under the International Whaling Commission in 1986 significantly reduced hunting, though recovery remains slow in some regions.
