"A four-finned robot ripples through the water, taking inspiration from the movement of cuttlefish.

Although the animal is better known for its powers of disguise and stunning communication skills, its undulating swimming motion is also noteworthy, allowing for efficient and agile motion.

Created by Pascal Buholzer and fellow students from the Swiss Federal Institute of Technology in Zürich, the copycat robot, named Sepios, demonstrates that its finned design can be an environmentally friendly alternative to propellers."
