Human technology has long drawn inspiration from the natural world: The first airplanes were modeled after birds. The designer of Velcro was inspired by the irksome burrs he often had to pick off his dog.
Although some have been designed to resemble real fish, robotic fish typically come in neutral colors and resemble their biological counterparts in shape only. Yet, according to Tsam Lung You, an engineer at the University of Bristol in England who was not involved in the review, even the most unrealistic robot fish are less disruptive to aquatic life than the average ROV. Unlike most ROVs that use propellers to get around, robotic fish swim like the animals that inspired them.
