17.Visitors to a Shanghai aquarium(海洋館)were surprised to see a robot shark. It was reported the electric-powered "whale shark "showed up in Shanghai in January.Developed by Chinese researchers,the 4.7-meter-long "shark" has mechanical fins.It can swim,turn and dive like a real shark.Bionic(仿生的)fish like this are not just for pleasing visitors.They can be used in many fields The bionic whale shark,for example,is used to check water quality and take photos of underwater animals and plants. According to iMedia News,military(軍事的)uses are also likely Bionic fish produce almost no noise.They will not be found by sonar.It means they can swim around submarines without being noticed Compared to antisubmarine aircraft,anti-submarine "fish" are cheaper and can work better. Along with military and research uses,underwater rescue(救援)and archaeology (考古)can also get help from bionic fish.Smaller robots can swim in and around sunken ships,sending all kinds of data back to people.With a 3 D scanner,people may even make models of sunken ships. Maybe most exciting,these fish can swim among real fish.With sensors and cameras,we can learn more about fish behavior,such as schooling--how small fish swim together to avoid predators -- and breeding(繁衍).If robotic fish are good at mixing in,we may also learn what it's like to get eaten by sharks!
