Golly, this doctor sure has strange looking furry porn on his wall... I wonder what animal this is supposed to be from? Is that like a lynx?
Scientists may have finally cracked the mystery of #whale song https://www.sciencefocus.com/nature/whale-song-mystery by dr. Helen Scales
"#Whales are known for their musical talents, but how can that be possible under water? Living whales recycle air through their #larynx, which means they can make sounds without choking on water or exhaling precious air."
Baleen whales evolved a unique larynx to communicate but cannot escape human noise https://www.sdu.dk/en/om_sdu/fakulteterne/naturvidenskab/nyheder-2024/baleen-whales paper: https://www.nature.com/articles/s41586-024-07080-1
"The toothed and baleen #whales evolved from land #mammals that had a #larynx serving 2 functions: protecting the airways and sound production. Their transition to aquatic life placed new and strict demands on the larynx to prevent choking... #BaleenWhales nevertheless can still produce sound with their larynx, but they have evolved novel structures to do so"
The iconic baleen whales, such as the blue, gray and humpback whale, depend on sound for communication in the vast marine environment where they live. Now researchers have for the first time found that baleen whales evolved novel structures in their larynx to make their vast array of underwater songs.

“We found that this U-shaped structure pushes against a big fatty cushion on the inside of the larynx," Professor Coen Elemans, one of the study's lead authors and a biologist at University of Southern Denmark, said in a statement. "When the whales push air from their lungs past this cushion, it starts to vibrate and this generates very low frequency underwater sounds."
“On the one hand, the baleen whales' unusual larynx endows them with a remarkable ability. They can vocalize at extremely low frequencies and in so doing communicate with other whales as far down into the ocean as 100 meters deep. At the same time, this low frequency makes the whales' vocalizations extremely vulnerable to human noise pollution like shipping traffic.”

#Larynx fossil suggests dinosaur may have been capable of making bird-like calls @CommsBio https://www.nature.com/articles/s42003-023-04513-x https://phys.org/news/2023-02-larynx-fossil-dinosaur-capable-bird-like.html
Paleontologists with Hokkaido University Museum working with a colleague from the American Museum of Natural History has found evidence that suggests one type of dinosaur may have been able to make bird-like calls. In their paper published in the journal Communications Biology, Junki Yoshida, Yoshitsugu Kobayashi and Mark Norell describe their study of a larynx fossil from a Pinacosaurus grangeri dinosaur and features that suggest it may have allowed the ancient creature to make bird-like sounds.
