Sei whales and their recent return



1. What are Sei whales?

Sei whales are known for their massive size and distinctive blue-grey coloration. They are one of the largest species of whales.

2. Why did Sei whales disappear from Argentina’s Patagonian coast?

During the 1920s and 1930s, relentless hunting by whaling ships operating along the shores of Argentina and beyond decimated Sei whale populations, causing their disappearance from the area.

3. How did Sei whales recover?

Global bans on commercial whaling implemented in recent decades have paved the way for their remarkable recovery. Sei whales breed every two to three years, which has contributed to the slow but steady replenishment of their population over the past century.

4. What efforts were made to track the Sei whales?

A team of scientists fitted some Sei whales with satellite trackers to map their migration patterns. They captured remarkable footage of the whales from boats, drones, and underwater, documenting their return to these once-familiar waters.

5. What is the significance of the return of Sei whales?

The return of Sei whales to the Patagonian coast serves as a powerful reminder of nature’s resilience and the importance of sustained conservation efforts in preserving Earth’s biodiversity. Their remarkable comeback after a century of absence is a beacon of hope for other endangered species.

6. What could jeopardize the recovery of Sei whales?

Any country withdrawing from the global moratorium on whaling could jeopardize the hard-won progress made in reviving Sei whale populations.
