The term "legendary creatures" refers to creatures from Endless Ocean and Endless Ocean 2 that significantly differ from other members of their species in terms of traits such as color, size, or some other extraordinary factor. These creatures are treated as special or unique by the game, often requiring the completion of certain tasks in order to unlock them.
These creatures lack specific measurements or scientific names barring the occasional estimate from a character. They also make up the only category in Endless Ocean 2's encyclopedia in which all of its entries have unlockable trivia.
In Endless Ocean, there are only two legendaries, one mandatory to find and the other optional. By contrast, Endless Ocean 2 features a total of twenty-six. While eight of them can be encountered during the story campaign, only three actually play a role in the plot. The remaining eighteen are all locked behind Notebook quests and/or special requests, with ten of which being locked behind simply beating a story chapter or the story as a whole.
Though legendary creatures can be placed in Endless Ocean's Aquarium, they cannot be in Endless Ocean 2. They will also disappear during Guided Tours, and will never appear in the Private Reef. Exclusively in Endless Ocean 2, discovering all but two legendary creatures will net the player a new title per specimen, with an extra title earned upon discovering all twenty-six.

Notes[]
- The "Coral Reef Life" and "Small Marine Life" sections are the only parts of the Marine Encyclopedia to not be represented by any legendary creatures.
- The "Large Marine Life" and "Dolphins and Whales" sections are also tied for the most representation among legendaries.
- The Singing Dragon and Okeanos's Guardian are the only two legendary creatures in Endless Ocean 2 which do not earn the player a title for discovering them.
- Although legendary creatures as a mechanic do not return in Endless Ocean Luminous, most creatures considered legendary in Endless Ocean 2 do return, instead classified as rare variants of their base species.
- The mechanic of legendary creatures was seemingly replaced by UMLs in Luminous, which similarly function as exceptional and rare creatures.
