If that was me, I'd be like Heimdallr hearing grass as it grows on the earth ! :-)
“Scientists have long understood the way dolphins and toothed whales have been able to hear underwater. These animals have a special type of fat surrounding their jaws which can relay sounds from the ocean to their ears. Now, thanks to a new study, scientists are able to understand how their toothless grazing cousins, the baleen whales are able to hear without these sound-enhancing jaws.”
