Scientists at Work: The Wonder of Blue Whales

Stat: 100 feet: At nearly 100 feet in length, blue whales are the largest animal ever known to have existed on Earth.

Story: Blue whales are big but they’re not invulnerable, often falling victim to strikes by ships in the northern India Ocean. Asha de Vos, a Pew marine fellow who founded Sri Lanka’s first marine conservation research and education organization, tells us about the beauty of blue whales and their importance to the health of the ocean.

They spend their summers in polar waters, feeding on krill. In winter, they migrate toward the equator to breed. The biggest of them live in the Southern Ocean, near Antarctica.

Asha de Vos is also an ocean educator. She co-founded the nonprofit organization Oceanswell to train and mentor youths from countries that do not have international and/or domestic support to protect their oceans. Through research expeditions, writing scientific papers and grant proposals, and guidance on how to discuss their research, they gain the tools they need to help protect their home countries’ marine life.
