Key Info
  • Special adaptations make the dolphin a champion swimmer
  • Duration: 03:07
  • Water is denser than air and slows humans down when we attempt to swim through it. By comparison the dolphin has no trouble slicing through the water at speed. Slow motion filming shows how human skin is distorted by the water with each movement, causing drag. The dolphin's thick, adapted skin does not distort making it a very efficient swimmer.
