they look sparkley

Hey! Look! That fucking fish is a sparkley robot! The designer of these fish says that "This work has many real-world applications including detecting leaks in oil pipelines, mine counter-measures and improving the performance of underwater vehicles." What about fighting off an armed dolphin?

Now I know these British scientists claim that these are "[t]he world's first autonomously-controlled robotic fish," but here's some evidence that an obviously superior American robot fish is on the way, courtesy of my uncle.
