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.
They both use sonar to locate things. The way it works is, they emit sound waves, and anything in close proximity to those waves bounce the waves off and they come back so that the bat/dolphin can hear them. This is how they tell how far away things are, since they don't have very good eyesight.
echolocation :)
by smell and eye sight
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.
Bats - and dolphins. They both use sound waves to find food.
dolphins bats porpoises and whales
it helps them locate a direct food source (the fish).
Bats use their sense of hearing to find food. They use echolocation similar to dolphins.
Most mammals do not have the ability to use echolocation. The mammals that do are bats and dolphins. They use it to navigate and locate prey even when it is difficult to see (for bats, that is at night and in caves, and for dolphins, it is useful in the water when visibility is reduced.
They use echolocation (a form of ultrasonic ranging) to locate their food.

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
Bottle nosed dolphins hunt individually and as teams. They locate fish by using echo-location, and are fast and agile swimmers, so they can pursue the fish and and catch it in their teeth.
Bats and Dolphins both use sound to navigate.
dolphins ,bats, and submarines all have echo location
