Dolphin whale

LocationThe Commonwealth

Dolphin whales, are creatures that can be found all across the Commonwealth, always dead, in the year 2287.


Heavily mutated since the Great War, these creatures can be found all along the coast-line, and have notably developed larger teeth, a shorter dorsal fin and pinkish-grey color. Since whale corpses build up large amounts of gas during the decomposing process, if enough physical force is applied, the rotting corpse will burst from the released gas.


  • While a proper name has not yet been given for this species, in the Fallout 4 game files, these creatures are referred to as both dolphins, and as whales.
  • All in-game appearances of the dolphin whales, are seen to be dead.
  • In the game files, there is an animated dolphin whale file, suggesting that in the quest, 20 Leagues Under the Sea, there was to be a live dolphin whale.


Dolphin whales appear in Fallout 4 and Fallout 76.
