Animal Propulsion Study Reveals How Jellyfish & Other Species Bend The Rules Of Motion (VIDEO)

By Jacqueline Howard

Nothing we have ever built can ply water as efficiently as the humble jellyfish. This video shows the pressure systems created with each of its thrusts, with vortices of low pressure (blue) rolling from the front of its bell-shaped body that meet up with the bulge of high pressure (red) that forms behind it:

This pressure gradient pulls the jellyfish through the water with little exertion. Research on jellyfish propulsion over the past 2 years revealed a key design feature that makes this translucent beast so efficient: bendiness. (This was confirmed by building robotic jellyfish—the bendy models left …read more
