All dolphins make sounds.
no its different from country to country
Dolphins are mammals so they reproduce the same way all mammals do.
Yes or else all the dolphins would not be here so the have babies
Whales, dolphins and porpoises are all cetaceans, and they all speak the same language in spite of making very different sounds. The reason this is possible is that the sound is not the communication, the communication is in the form of digital information imprinted on the sound waves themselves. If you have ever heard any cetacean voices, you have probably noticed a strange "Tinny" quality to their vocalizations. This is because there is a seemingly random pattern of peaked and chopped-off sound waves in every sound cetaceans make, except for intestinal noises, and it is this combination of sound waves that actually carries the message. Anyone who has ever worked with dolphins will tell you that they have amazing telepathic abilities, and there is no reason to think they don't use this form of communication among themselves. Pods of captive dolphins will frequently jump from the water in perfect unison with no apparent vocal or visual communication whatsoever
Well, .........you know some food like shrimp, jellyfish, lobster and you get the point right?
All use sound navigation / echo-ranging for navigation.
Yes they do, which also means that's they make a sound and see if bounces off an object to see if something is there, they do this because they don't have good vision so that helps them if there is danger or if they're looking for something.
Dolphins are vertebrate's. they have back bones the same as humans whales and all other mammal's.
The show Party Down had a character say the happiest sound is the world is dolphins laughing
The Songs All Sound the Same was created in 1992.
We don't actually all sound the same, we do sound different. But if you mean that we sound the same if we sing in tune or pitch.
