Whales lost their teeth before evolving hair-like baleen in their mouths (Thu, 29 Nov 2018)
Rivaling the evolution of feathers in dinosaurs, one of the most extraordinary transformations in the history of life was the evolution of baleen -- rows of flexible hair-like plates that blue whales, humpbacks and other marine mammals use to filter relatively tiny prey from gulps of ocean water. Now, scientists have discovered an important intermediary link in the evolution of this innovative feeding strategy: an ancient whale that had neither teeth nor baleen.

Whale songs' changing pitch may be response to population, climate changes (Thu, 29 Nov 2018)
Blue whales have been dropping pitch incrementally over several decades, but the cause has remained a mystery. A new study finds a seasonal variation in the whales' pitch correlated with breaking sea ice in the southern Indian Ocean. The new research also extends the mysterious long-term falling pitch to related baleen whales and rules out noise pollution as the cause of the global long-term trend, according to the study's authors.

A bigger nose, a bigger bang: Size matters for ecoholocating toothed whales (Thu, 15 Nov 2018)
A new study sheds light on how toothed whales adapted their sonar abilities to occupy different environments. The study shows that as animals grew bigger, they were able to put more energy into their echolocation sounds -- but surprisingly, the sound energy increased much more than expected.
