Antarctic Octopuses: The Secret To Surviving The Coldest Waters On Earth

#shorts #Antarctic octopuses #extreme cold #researchers #amino acid structure Scientists have discovered that Antarctic octopuses have a special protein that allows them to survive in freezing waters. The protein is called the sodium-potassium ion pump, and it helps the octopuses pump sodium ions out of their cells and bring potassium ions in. This process is critical to bringing neurons back to “rest” after activity. Scientists found that the Antarctic octopuses have a different version of the sodium-potassium ion pump than other octopuses. This version of the pump is more efficient in cold water, which allows the octopuses to survive in Antarctica. The scientists are now studying other membrane proteins to see if they find other adaptations that help animals survive in extreme environments.
