The tentacled artificial creature, made from silicon, has been dubbed “Medusoid” because of its resemblance to the snake-haired character from Greek mythology whose gaze turned people to stone.

By applying an electric current to a container of conducting liquid, the scientists demonstrated they could “shock” the muscles into contracting so that it began to move through the water.

The “reverse-engineering” project by researchers from the California Institute of Technology and Harvard University was published on the website of the Nature Biotechnology journal.
