Doctor Anna's Imaginarium

//If you’ve seen manatees up close and observed them for a while, no doubt you’ve seen some bubbles nearby. Sea cows often release gas as a part of their daily routine. But, from a scientific standpoint, there is research that shows manatees can control their buoyancy from farting. They use their digestive tract and the unmistakable flatulence they exhibit as a way to rise and sink in the water. But how does a fart make a manatee go up and down? Well, the sea cow can “hold it in” and that gas makes them a little lighter helping them to float near the surface. Or the manatee can “let it rip” releasing some gas and sink a little lower in the water. This releasing of gas isn’t like a jetpack on their back, zooming them to the bottom. But it does help them to slowly sink lower towards the bottom.// ... But they also have specialized lungs ..
