dolphins are very intelligent animals when its dark they can not they send sounds out to find wear there going and to catch food.
Hearing is the most valuable sense to a dolphin, as they use echolocation to navigate, communicate, and locate prey in the ocean.
they will send out the sound and once it hits the fish, the sound waves bounce back to the dolphin forming a picture for them.
well the sound that it makes is kind like a crying sound, or mostly like a whistle!

dolphins use their melons to produce sound waves.
When an animal uses sound to find food or navigate it's called echolocation, the sound bounces off surfaces around the dolphin. They hear where the sound has bounced off prey and follow the sound, hence allowing them to change direction quickly.
The O is long vowel sound and I is a short vowel sound

Well they use ecolocation (a type of sonar) to track food and predators and such. They give out clicks, and whistles and then the sound bounces off the object and gets absorbed back into the dolphin's forehead.
By the sound it makes.
