Dolphin Free Screensaver. Photos slideshow. Dolphin screensaver. This free screensaver contains many pictures of Dolphin. Dolphins are aquatic mammals that are closely related to whales and porpoises. There are almost forty species of dolphin in seventeen genera. They vary in size from 1.2 metres (4 ft) and 40 kilograms (88 lb) (Maui s Dolphin), up to 9.5 m (30 ft) and ten tonnes (the Orca or Killer Whale).
