What happened

After commercial whaling nearly erased them, blue and fin whales are slowly reclaiming the southeast Atlantic Sadie Harley Scientific Editor Robert Egan Senior Editor More than 40 years after the end of commercial whaling, new research reveals a recent…

Why it matters

The findings, published in the African Journal of Marine Science, compiled more than 60 years of confirmed sightings and strandings from Namibia and South Africa's west coast.

Common ground

Although overall numbers remain low, sightings of both species have increased markedly in recent years—with 95% of observations recorded since 2012.
