Dolphins are marine 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). http://en.wikipedia.org/wiki/Dolphin
A lot.
dolphins can weigh from 88lbs to over 10 tons, but if you mean the bottlenose dolphin (like flipper) they weigh 330 to 1430 lbs
Before being harpooned dolphins generally wiegh about six times in their short lives. I believe the dolphin from the Nelson Mandela movie wieghed only twice, but he is famous now. You win some you lose some
