Amazing Footage Of Jelly Fish Spinning

Victor Devalles a photographer who recently happened to be snorkelling off the Spanish coast managed to capture a shot clip of a jellyfish that was accidently caught in a 15-second long spin after coming into contact with an air-filled bubble ring. Mr Devalles was actually responsible for creating the bubble ring but never meant for the jelly fish to be sent into a high-speed whirl. He says his intention was to capture footage of a jelly fish swimming through the bubble ring.

Meeting a vortex

In an interview with the Daily Mirror he said that the jelly fish touched the edge of the ring and was sent into a dizzying spin. Bubble rings are actually a type of vortex and divers have the ability to create them by exhaling air in a specific way whilst facing the surface of the water. If the air bubble is large enough it can turn into a donut shaped ring that grows in size as it continues to float to the surface.

Water pressure

Scientists say the water pressure at the bottom of the bubble is higher than it is at the top so the pressure forces the air up quicker. What that means is the bubble is squeezed until the bottom finally meets the top which then punches a hole in the bubble’s middle through which water flows. The ring which is buoyant starts to become more stable at the vortices spin faster.

Uninjured

If left undisturbed the rings can reach all the way to the surface. However, if an unsuspecting jelly fish crashes into one, then all that energy can be transferred onto the jelly fish in spectacular manner. Fortunately, in this instance, the jelly fish seemed to come away uninjured after the spin says Mr Devalles. It is likely that jellyfish are used to turbulence in the currents. According to research the species is well adapted at reorientation when they do get swept of their trajectory and will swim against the current if they feel they have lost their way.
