The Risso's Dolphin is a rare, deep-sea dolphin that makes an appearance in both Endless Ocean games.

In-Game Description

"This grey dolphin has a large rounded head. As it grows older, its skin gradually becomes white. It has no teeth in its upper jaw, and sometimes no teeth at all.

It swims the seas leisurely in groups of up to several dozen.

[White Scars]

Adults look white because of countless scars on their skin. All dolphins and whales are injured at some point, but their scars usually fade with time.

This species' injuries leave permanent white scars which gradually turn their entire body white as they get older."

In Real Life

Risso's Dolphin was first described in 1812 by Antoine Risso, who's description formed the basis for the first public description of the dolphin by the famous naturalist Georges Cuvier. Risso's dolphin live in in the Pacific and Indian oceans along the coasts of almost all continents. They live on the continental shelf, between 400-1,000 meters (1,300-3,330 feet). They feed almost exclusively on squid. They are also known for harassing and riding in the wake of grey whales.


Endless Ocean

These dolphins are found in the Abyss, in Secret Cave.

These swim together, at very deep depths.


  • In EO, these are only found during the daytime
  • In EO2, these can be found day and night.
  • Its unknown why they are found at such. Its presumed that its because they have the same adaptations of the Sperm Whale.
