Imagine a species with fewer individuals than seats on a school bus. Now imagine that each weighs more than the bus itself.

Specifically, the marine mammals can sing at extremely deep frequencies that are “completely undetectable” to orcas, according to a study published on Jan. 31 in the journal Marine Mammal Science. “It ...

Killer whales are the only natural predator of baleen whales—those that have "baleen" in their mouths to sieve their plankton ...

Incredible footage showing a man briefly being 'swallowed' by a whale is the latest in seemingly similar, yet mostly benign ...

Learn more about how baleen whales split into two groups — fight or flight — and how these groups determine how loud they ...

Scientists estimate that about 50 are left. These whales were thought to belong to a more abundant species, Bryde’s whale, until 2014, when DNA taken from skin samples showed that they were unique.

New research finds some baleen whale species call at such deep frequencies that they're completely undetectable by killer whales, which cannot hear sounds below 100 hertz. These also tend to be the ...
