Something called echo-location
dolphins bats porpoises and whales
Well they can see. They also use echo location of sorts aswell though.
Sonar is a system that locates objects by transmitting sound waves and detecting the waves when they are reflected off of objects. Bats and many other animals, such as whales and dolphins, use natural sonar to navigate and capture
Bats - and dolphins. They both use sound waves to find food.
Dolphins chase fish, get their sense of direction, and maneuver the ocean through echolocation. Basically, like bats, they send out waves that bounce back and help them navigate, locate prey, and avoid obstacles. They can even use this to locate fish hiding in the sand.
Sonar uses echoes to locate objects by bouncing sound waves off them and detecting the echoes.
dolphins make sort of high-pitched shrieking noises. when they send out their sound waves, the waves bounce off objects near the dolphins and come back to the dolphin, which is how they locate prey without their eyes. this is called echolocation, and is also used by bats. the sounds of dolphins are really quite beautiful if you ever get the chance t ohear them
Hector dolphins use echolation to find food. they send high frequency clicks that bounce off surrounding objects and fish giving the dolphins a detailed picture and information on how fast the object/fish is moving. (to locate prey) They swim in pairs or groups up to 12.
Bats and dolphins find their food and navigate through a sensory system called echolocation.Echolocation is a physiological process for locating distant or invisible objects (such as prey) by emitting sound waves that are reflected back to the emitter by the objects. It is used by an animal to orient itself, avoid obstacles, find food, and interact socially.
