seems some scientist came up wqith a truely robotic fish. it uses 3 moving joints to make the realistic swimming motion, which is neat considering how many muscles fish actually use. its comepletely submersible and recharges in an hour, the ones I saw on tv were about the size of a large bass, they claim that in the next few years every home aquarium will have these instead of real fish lol
