Echolocation is a sensory system in certain animals, such as bats and dolphins, in which usually high-pitched sounds are emitted and their echoes interpreted to determine the direction and distance of objects.
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.
Not with the naked human eye. The eye needs at least a little light in order to be able to see. With special equipment, we can measure things like infrared heat and "see" even if there is no light, but that's not really seeing because you're using machines instead of your eye.
they let a high pitched sound out of their mouth and it echo's back if it's hit's something if not it keep moving until i does Many types of bats as well as aquatic mammals such as whales and dolphins regularly use echo-location to find food and find their bearings.
Echolocation is something bats, humans and dolphins do. Dolphins have developed special organs to do it, and can make up to 200 clicks per second. To do it you just put your tongue to the roof of your mouth (while in a place that will echo) and quickly bounce your tongue backwards off your teeth. After some practice, you should be able to tell the depth, height, and width of something. If you keep working, you might even get good enough to tell if some thing's warm or cold. Remember, this took me six months to accomplish so don't give up if you don't get it in the first few weeks.
