they use SONAR. :)
Dolphins hear with their ears BUT when it comes to their sonar they 'hear' with their jaw.
yes
they hear noises
Dolphins can hear human voices, but their ability to understand them is limited. Dolphins primarily communicate through a complex system of clicks and whistles, which are adapted to their underwater environment. Human voices produce sounds that may not resonate well in water and fall outside the frequency range that dolphins typically use for communication. As a result, while they can detect human sounds, the nuances of human speech are not easily interpreted by them.
As dolphins are mammals they breath air like us, humans.
dolphins are mammals, not fish. They have lungs, not gills, and breathe air.
Dolphins must go to the surface, because they breathe air. Dolphins are mammals, not fish.
no
Dolphins are mammals, they Breathe air. If trapped underwater they eventually suffocate or drown.
A few dolphins can be found at the Underwater World in Sentosa. The future Integrated Resort (IR) at Sentosa will also have dolphins.
