Document Summary
First fish perceives a prey in front of it. Middle fish should be discriminating b/w the predator and the prey. Last fish need to pay attention to the predator at its back. Buster needs to eat bubbles to survive and pass on its gene. Bubbles needs to run away from the buster to survive and pas on its gene. So there"s spike b/w them all the time. Evolutionary arms race: prey needs to get faster and predator needs to get faster as well. This is the feature that animals have evolved to have. Using sound wave-- which is above what humans can hear--very high frequent sound. Bat directs its sonar beam at a target then bat receives the returning waves to determine the location of the prey. Bats do this-- but interestingly some humans do this as well. For bats, when they locate their prey, it"s not just sending out waves and detect the prey--it"s not that simple!
