The evolution of menopause in #ToothedWhales https://www.nature.com/articles/s41586-024-07159-9

"menopause is something of an evolutionary blip. We are one of the few #animals to experience it... There are five species of toothed #whales that undergo menopause — short-finned #PilotWhales, #FalseKillerWhales, #KillerWhales, #narwhals and #belugas — making it the type of animal that is known to have evolved menopause most frequently."

These #Whales Still Use Their #VocalCords.
Unusual experiments on organs recovered from three carcasses suggest how #baleen whales call out at #sea. #Toothedwhales, like #spermwhales and #dolphins, use their larynges like a cork to seal their airways; they evolved a way to produce sounds in their nasal cavities instead. But #scientists suspected that filter-feeding #baleenwhales, including the musical #humpbacks and huge #bluewhales, still use their voice boxes. https://www.nytimes.com/2024/02/21/science/whale-song-voice-box.html?unlocked_article_code=1.XE0.Ohuo.tSXoT0veB5Lc&smid=url-share

Inspired by a story we published last year about the first confirmed live sighting of Sato’s beaked whales, artist Rozi Hathaway created a comic version! She included info about Hal Sato, a Japanese researcher dedicated to locating these evasive whales.
