Bio engineers from Harvard University have created an artificial jellyfish using silicone and muscle cells from a rat’s heart.

Scientists have named the synthetic creature a Medusoid. When placed in an electric field the Medusoid pulses, and swims. 

“Morphologically, we’ve built a jellyfish. Functionally, we have built a jellyfish. Genetically, this thing is a rat,” says Kit Parker, a biophysicist at Harvard University.
