#SpermWhales “Regularly” Toot Gas To Hang Motionless In The #Ocean While They #Sleep
“Because the oils are lighter (less dense) than other parts of the body, this causes sperm whales to passively rotate to the iconic head-up posture that we can see in photographs and observe using animal-attached tags.”
As they sleep, sperm #whales vent gas up to 11 times per rest to maintain neutral buoyancy. They “regularly” release a little air, which allows them to sink down again.

💁🏻‍♀️ TIL: 🐋⚓ Sperm whales near #Dominica shorten their click sequences and shift their vowel-like #sounds when #ships are present, according to researchers from #ProjectCETI and #UCBerkeley.

The team analyzed over 1,000 codas from 15 #whales over four years, finding that rhythm and click timing best predict nearby #vessels. The findings add to efforts to decode whale #language and understand how human noise affects #marine life.

💁🏻‍♀️ TIL: 🐋🗣️ Sperm #whales in the #Mediterranean are splitting into two dialect groups: eastern whales clicking faster, western whales clicking slower, according to researchers.

By studying over 5,000 recordings from #Greece and #Spain, scientists discovered distinct regional accents.
