Happy Jellyfish Day! Jellyfish have a distinctive way of moving, using their bell-shaped bodies filled with a gel-like fluid instead of bones. To propel themselves, they contract their circular muscles, forcing water out in the opposite direction. This allows them to swim efficiently while also drifting with ocean currents. Their method of propulsion is a fascinating adaptation to their aquatic environment. . . . #lindbladexpeditions #jellyfish #exploremore
