The Blue Whale is a whale that appears in both games. It was the largest creature in the games until the Ancient Mother was discovered, and is the largest animal in the world.

In-Game Description

"Known for its huge bluish-grey body, this is the largest mammal on Earth with some over 30m long. The water it blows can reach 10m high, and the 60 or more ventral pleats in its throat open when it feeds.

It travels widely, and its call contains low frequency wavelengths that travel well in water and allow it to communicate with other whales for up to 150km.

[Extinction Through Progress?]

Hunting blue whales has always been difficult because of their size and speed, and the total population was once around 300,000. But with the introduction of faster whaling vessels and explosive harpoons at the end of the 19th century the blue whale was hunted to the brink of extinction.

Even now, decades after whaling bans were enacted, the blue whale population is less than 5,000 and they are still at risk of extinction."


Endless Ocean

It is found at the Great Drop-Off as part of the process of finding the White Mother.

Endless Ocean 2

This is first seen in the Weddell Sea, as it creates The Song of Dragons heard inside the Iceberg Cavern. After that it is found swimming around the North Coast of Canada at a depth of 60 feet (18 meters).


  • There may be two Blue Whales in the Arctic Ocean. Some players report seeing a Blue Whale on each side of their divers when they trigger the Ice Mosaic cutscene, though that may be the White Mother, if they have already unlocked her appearance by collecting the Whale Ornament.
  • This is one of Jean-Eric's favorite creatures.
  • The Blue Whale is a baleen whale, meaning that it has a keratinous filter in its mouth instead of teeth that it uses to feed on small organisms like krill and plankton instead of other prey. Other baleen whales include the Humpback and Grey whales, and the only two examples of toothed whales in the game (excluding all of the species classified as "dolphins") are the Sperm and Killer whales.
