SWIMMING

Dolphins breathe air, and must come up to the surface of the water regularly.   They only have one nostril, located on the top of their head.  This is called a blowhole.   They use the blowhole to breathe, but they have no sense of smell!    Dolphins may seem friendly, but they are still wild animals. Never swim up to a wild dolphin!

DOLPHIN SOUNDS

Right now, there is no evidence that dolphins have a language like us, but they definitely communicate.  They tell each other about the location of food and dangerous animals, and they have a great sense of humor.  The dolphin’s echo-system or SONAR, may be able to see inside other animals.   So, the dolphin could tell if a shark’s stomach was empty and let the other dolphins know "hungry shark nearby - danger!" Or a Sea World dolphin could tell if his trainer was upset if her heart was beating really fast.   Dolphins can perceive many things that people can’t.   They may not have a true language, but they definitely communicate.
