The Atlantic Tarpon (Megalops atlanticus) is a large fish.

In-Game Description

Length: 8 ft. 2 in. Covered in large, gleaming silver scales, this ancient fish displays primitive characteristics such as the shape of its jaw. Its young spend time in a leptocephalus stage, which is a developmental phase for eels. Little is known about this stage and the connection to eels is puzzling. Sometimes called the "silver king", this fish is highly sought by amateur anglers.


Endless Ocean

This fish is found in the Marige Atoll Ruins (Mo'ia Atoll Ruins), mainly in the room before the Prince's Room. This room is accessible both from outside of the ruins (the hole in the roof) and from inside (a current sweeps the player into this room).

Endless Ocean 2

Two of these fish can be seen in the Cavern of the Gods in the Altar of Osiris.


These swim solitarily in both games, usually with other fish.


  • In Endless Ocean 2, players can still find these before the end of the main plot. If the player completes Part 4 of the "Help Me!" request first. There, the diver will be looking for 5 Atlantic Tarpon in Cortica River Midstream.
  • These can be found day and night in both games.
