Rorqual whales, including blue whales and minke whales, don't have teeth. Instead, they eat tiny sea animals by filtering water with comb-like bristles in their giant mouths called "baleen." Working in symphony with an array of rorqual-specific traits, a newly discovered sensory organ builds an even stronger case for their special creation.

Panda bears are restricted to remote mountains in China and have similar-sized bodies today. But fossils show that in years past some were mini-pandas, while others were giants. Plus, they lived in places far-flung from China. A new find described a mini-panda fossil fragment from Spain, reviving questions about the origin, migration, and demise of panda bears through history.
