Nature is beautiful,
and endlessly inspiring

The jellyfish
(is not actually a fish)
has no brain
has no heart

When we think about moving in  water, we tend to think about moving forward by pushing water backwards.
As do most fish and you and me when we swim. We spend a lot of energy...

This creature does not. It moves by contracting and relaxing its bell-shaped body. Besides very graceful, it is also very efficient.

It inspired development of a different way of moving in water, with potential in transportation but think also about medical technology administered through our blood.

An artificial -jellyfish-, engineered to pump its way through water, much as a human heart pumps blood through the body.
