Facts About Dolphins

  • Dolphins sleep in an unusual manner. One half of their brain sleeps while the other half stays awake.
  • Dolphins can exhale and inhale, filling their lungs completely, in three tenths of a second.
  • Dolphins are fantastic swimmers and jumpers. They can swim at 25 MPH and jump 15 to 20 feet in the air.
  • Dolphins possess a biological sonar system called echolocation. They can see with sound. Scientists and engineers are awed by the complexity and sensitivity of "dolphin sonar". Dolphins can see through some substances and see an object that is directly behind another object in the water.
