@dr.g_and_the_sea: E35.What happens to a whale in freshwater?

But staying there too long can cause some surprising changes to a whale’s body. #humpbackwhale #humpback #whale #whales #RioTheWhale #SacramentoRiver #California #SanFranciscoBay #cetaceans #marinemammals #freshwater #saltwater #osmosis #whaleskin #animalphysiology #animaladaptations #marineanimals #marinebiology #marinescience #marineecology #oceanbiology #oceanlife #marinelife #ocean #oceanography #oceanscience #oceanfacts #whalefacts #animalfacts #biologyfacts #sciencefacts #science #sciencetok #learnontiktok #stem #fyp #HowTheOceanReallyWorks
