The Sea Serpent is a legendary creature found only in Endless Ocean 2.

It is one of three prehistoric creatures in the game, alongside the Anomalocaris and the Cameroceras, though it is the only one whose discovery is not tied to collecting constellation coins.

The title "Magical Beast" is obtained upon discovering it.

Description


Trivia


Location

Endless Ocean 2

It can be seen in Ciceros Strait in South Canyon, swimming outside the diving range from around D-8 to F-8. Since it can't be focused on, the player receives both its basic information and trivia upon the first encounter with this creature. It only appears during the daytime.

How to Find It
After one of the parts in the Young Entrepreneur quest, the player will unlock a quest in their notebook telling of reports of "a dark shadow in southern Ciceros Strait" that the player must investigate with Oceana. As soon as the pair swims to the southern limits of Ciceros Strait's South Canyon, a cutscene will play, showing the strange creature, and the player will obtain its information and trivia, as well as completing the quest in their notebook. Oceana will then request that this discovery be kept a secret, to which the player can respond with a yes or no. If the latter is chosen, then she will repeatedly ask the question again until they pick yes.

Endless Ocean 2

Introduction

Oceana: "The black shadow that the other map companies discovered is definitely around here somewhere."
Oceana: "Look! Look at that! Grandpa, is that what I think it is?"
Jean-Eric: "What's up? Did you find something cool? What in the world is that thing?! No way! It's a sea serpent! I thought they were just a thing of legend. Guess not."

[...]

Oceana: "Oh, it's gone..."
Jean-Eric: "Oceana. What are you going to do?"
Oceana: "I... I'm... I'm going to keep what I've seen here a secret. If this became public, this place would be swarmed by divers and photographers. He wouldn't be able to live here in peace anymore. You agree with me, don't you?"

Notes

  • This is one of Jean-Eric's favorite creatures.
  • As one of the three long-extinct creatures (the other two being the Anomalocaris and the Cameroceras) that appear in Endless Ocean 2, this creature does not appear in the player's Marine Encyclopedia as a silhouette, and instead only appears on a brand new page after it has been discovered.
  • At least one living plesiosaur is set to appear in Endless Ocean Luminous, but it is unclear whether this is the Sea Serpent or a completely different one. It could be an Elasmosaurus.

Real-Life Information

  • The Sea Serpent is not a serpent at all, rather it is actually most likely a late surviving member of the order Plesiosauria, bearing a close resemblance to members of Elasmosauridae. If that is indeed the family it is the part of, it would have presumably have gone extinct towards the end of the late Cretaceous period, about 68-65 million years ago.
    • Plesiosaurs are part of the superorder Sauropterygia, which is a member of Pantestudines, the group that also includes turtles. Therefore, the closest relatives of the Sea Serpent in the game are sea turtles.
    • One minor inaccuracy surrounding the Sea Serpent, if it is supposed to be based on a real animal, is that it should have a layer of blubber surrounding its body, and a tail fluke.
