Is there a difference between the beluga whale and killer whale?

definitely a killer whale, they are about 32 feet 2.6 - 9 tons belugas are about 6 1/2 .4 - 1.5 tons the orca (killer whale in case you didnt know) is actually part of the dolphin family, its not a whale, it is technically the largest dolphin
A killer whale is bigger it can grow up to 27 feet long and weighs about 8,000 to 12,000 pounds a beluga whale can grow up to 15 feet long and weighs about 3,300 pounds
