Jellyfish Turned Out to Move as Vacuum Cleaner


Stanford University specialists found that, contrary to popular belief, floating jellyfish does not throw water in the opposite direction. On the contrary, it sucks in the water in front of it to create a low pressure area. Water rushes in this area and pulls the jellyfish.

This information was found during the experiment in a large tank filled with not only water but also small glass balls, which helped to see in what direction the water was moving, when the jellyfish moved. A special computer program recorded the changes in pressure.

The researchers believe that their discovery could make a real revolution in the construction of submarines, as a mechanism similar to the one used by jellyfish is able to save large amounts of energy.
