Whale baleen is one of the most remarkable anatomical traits Northern Arizona University Endocrinologist Kathleen Hunt has ever worked with. “The more I look at it, the more fascinated I get,” she ...

Baleen whales have a special structure in their mouth that enables them to filter feed. Instead of teeth, they have baleen plates that hang down from their upper jaw. These are made from keratin – the ...

Both toothed and baleen (filter-feeding) whales are among the largest animals ever to exist. Blue whales, which measure up to 100 feet (30 meters) long and can weigh over 150 tons, are the largest ...

Baleen whales eat between 10 and 20 tons a day, a 2021 Nature report found. That’s the caloric equivalent of eating 70-80 thousand Big Macs per day, the researchers told NPR. What do blue whales ...

Or corticosterone—which did peak during the entanglement of 2301—might be a better marker for stress in whale baleen. Right whale 2301 swims with her calf in 2002.

"Baleen whales are enormous and need huge amounts of food. This makes them vulnerable to changes in the environment, but this is also compounded by their survival strategy," Rogers said.

Having shown that it’s possible to identify whale species from baleen, Solazzo says, “Now we have a new tool to study those collections.” Lucia RM Martino, NMNH Rocky, flat, and all but free ...

Scientists have long struggled to study how whales produce sound. A new paper in the journal Nature paints the most complete picture yet of how baleen whales produce their iconic, haunting calls.

Baleen whales, like blue whales, gain a lot of energy relatively easily when they gulp up massive mouthfuls of krill or other small creatures.

Other baleen species, including gray whales and northern and southern right whales, have also been observed interacting with seaweed. After seeing videos of kelping and reading a 2012 study on the ...
