I think so, they also hear higher frequency sounds.
No, we can't hear what they say. Some people are convinced they can communicate with dolphins, but normal humans can't.
Not for humans with out special adaptive devices.
Humans cannot hear the high-frequency sounds produced by dolphins because their hearing range is different from ours. Dolphins communicate with each other using ultrasonic frequencies above the human hearing range, typically between 20-160 kHz, which is why we cannot hear their sounds.
Dolphins hear with their ears BUT when it comes to their sonar they 'hear' with their jaw.
Animals such as dogs, cats, and certain insects can hear ultrasound frequencies that are beyond the range of human hearing. Whales and dolphins can also detect sounds in the infrasound range, which are lower than what humans can perceive.
That is simple.. Dolphins, Chimpanzees and Humans, are different from most mammals because they have similar bones in there body. Why don't you look their systems in their bodies to compare.
No, they just use echolocation to tell where things are. Echolocation is making shrill sounds that humans can't hear that bounce off things. The dolphins have special organs that allow them to hear these sound waves.
No, dolphins cannot rape humans.
No, dolphins and whales are dolphins and whales, members of the Order Cetacea. Only people are humans. Humans, like dolphins and whales, are mammals. But humans are members of the Primate Order.
You can't! Dolphins are whales.
There is no scientific evidence to suggest that dolphins rape humans. Dolphins are known for their intelligence and social behavior, but there have been no documented cases of dolphins sexually assaulting humans.
