South Blue

Blue-Finned Elephant Tuna

An Elephant Tuna.

A Blue-Finned Elephant Tuna (エレファント・ホンマグロ Erefanto Honmaguro?, Elephant True Bluefin in the Viz Manga and Titanic Tuna in the 4Kids dub) is a fish that comes from the South Blue and has elephant-like features. It is classified as a type "A" creature, "Big Friendly".[2] The first one appeared in Chapter 98 and Episode 51, in which Sanji bought/won from Loguetown.

Sanji bought one, while in the anime, Sanji competed in a contest against another cook, Carmen and won it. Once the Straw Hat Pirates reached Twin Capes Lighthouse and settled down, Sanji prepared the fish into an elaborate meal for everyone while they were speaking with Crocus in Twin Cape. Usopp and Sanji were paying attention to Nami and Crocus's conversation while, unbeknown to them, Monkey D. Luffy ate up the rest of the fish, including the bones.

The following events are Non-Canon and therefore not considered part of the Canon story.

One was a trophy by Jonathan.[3]

Another one has appeared in the Thriller Bark, when Oars, powered by Luffy's shadow demands food to satisfying his hunger, a large bundle of food was provided, including an elephant tuna. While feeding Oars, the zombies realized that it was a salted fish that could kill Oars if he ate it. The zombies got rid of it at the last second.[4]

Another one has made its appearance around Little East Blue, where it was fished up by Luffy, Usopp, and Brook, but was carried off and eaten by a gigantic beetle called Boss.[5]

Concludes non-canon section.

Non-Canon Animals


A Sennenryu (千年竜 Sen'nen-ryū?, literally meaning "Thousand Year Dragon" or "Millennium Dragon", known as a Millennial Dragon in the FUNimation dub) comes from Warship Island's mostly submerged Dragon's Nest.

Every 1000 years, they return to the nest to give birth and die. Their bones, when extracted to create an elixir, can grant eternal youth, which is what Nelson and Eric desired. The only named one is Ryu, though a huge group did gather during the Dragon's Nest's rising. They only appear in the anime in the Warship Island Arc, and first appeared in Episode 55, but are also referenced in the Ocean's Dream arc.

Their appearances in the series created a plot-hole, as Zoro later commented that he did not believe in the existence of dragons.[6]
