o
They use sound to communicate and they use sound to find food, that's why sound is important to beluga whales.
Whales use sound waves to talk to other whales in their own language
by vibrating water
Abiotic factors (non living) that whales use include oxygen, water, sunlight and vibrations (sound waves).
They use ultrasonic. The sound they use to locate objects that may be invisible.
Whales and dolphins use biosonar for communication and also for navigation .
they use underwater echo sound location!
Bats use high-frequency ultrasonic sound waves for echolocation, while whales use lower-frequency sound waves called infrasound. Both species emit these sound waves and listen for the echoes that bounce back off objects to navigate and locate prey.
To find food, whales (and dolphins) use echolocation, which uses sound waves to locate krill or fish. they filter krill out of the water
Whales sense sound waves through a fatty, oval shaped organ located in the forehead of all odontocetes (toothed whales). It is believed to be a bioacoustic component, meaning it focuses echolocation so as to use the least amount of energy to communicate.
It's called echolocation or ''Clicking" language.
SOund NAvigation and Ranging = SONARMost familiar to the general public from its use by military vessels, whales, and bats.
