Animal Species/Fish-Man Island Saga

Kraken


Kraken (クラーケン) is a massive, boneless, octopus-like creature several hundred times larger than the Thousand Sunny. Unlike a regular octopus, it has a turtle-like head without a beak between the arms. It is also known as the "Monster of the Arctic" (北極の怪物). The only seen example of one is Surume, who was introduced in Chapter 604. Hody Jones went all the way to the North Pole to kidnap Surume for his use, due to its fearsome power, he only managed to keep it under control by holding its brothers, family and species as hostages. Some can have an estimated length of 300m (984').

When the Straw Hats first encounter one on their way to Fishman Island, several crushed pirate ships can be seen between its massive tentacles, indicating that it feeds on the ships and crew it pulls down into the ocean. Caribou recites a story about it, calling it "the enemy of the human race" and that it "never knows satisfaction where killing is concerned". He found it odd that one would be living near the Red Line. Hody also mentioned that, as a legendary creature, a Kraken can be sold for a high price, even if dead. It is unknown if these tales of its ruthlessness are true, as the one encountered by the Straw Hats was entirely pleasant once they befriended him, its possible his violent actions before were done merely at Hody's whim.

Sea Lion


The Sea Lion (海獅子) is a sea monster that lives in the depths of the ocean. One was seen in the New Fishman Pirates' army of sea monsters just outside Fishman Island in Chapter 607, which was later ridden by the Flying Pirates during their attack at Ryugu Kingdom. It may be based on the sea-lion, a mythical creature in heraldry with of the head and front limbs of a lion with the tail of a fish, or the merlion, another mythical creature with the head of a lion and the body of a fish. It is a visual pun on real-life "sea lions". It is 55m (180' 5") by estimate in length.

Sea Bear


The Sea Bear (海熊) is a sea creature that lives on the ocean floor. The only one seen is under the command of the New Fishman Pirates, and it appeared first alongside the Sea Lion and many other sea beasts under the crew's command in Chapter 607. It was on a rampage, but stopped when some fishmen tried to frighten it with fire. The kanji for sea bear can mean "fur seal" in Chinese, which the sea bear somewhat resembles. It is 50m (164') by estimate in length.

Sea Rhinoceros, Sea Gorilla, Sea Elephant, and Sea Giraffe


The Sea Rhinoceros (海サイ), Sea Gorilla (海ゴリラ), Sea Giraffe (海キリン), and Sea Elephant (海ゾウ) are sea monsters that live in the depths of the ocean. They were seen as the New Fishman Pirates' army of sea monsters just outside Fishman Island in Chapter 607, and were later ridden by the Flying Pirates during their attack on Ryugu Kingdom.. The sea elephant is a visual pun on real-life "sea elephants".

Sea Turtle Elevator


The Sea Turtle Elevator (ウミガメエレベーター) is a large turtle that has been tamed by the people of Fishman Island. It is used by the people (though most likely mainly by humans) to ferry them from the lower levels of the Coral Mansions to the surface and back again. The turtle's shell is large enough for several average-sized humans to stand on comfortably and has a bubble covering it which holds air for humans to breath.

Fish Taxi and Fish Bus
The Fish Taxi (お魚タクシー) is a large fish able to hover over land, thanks to a coating bubble, and swim in the sea and is used as transportation to cross both terrains. The coating bubble is on its back, with seats aligning it's dorsal fin. It also wears a hat. There is also the Fish Bus (お魚バス) which is used to go around the Island in a similar manner to a regular bus.

Long Flounder


The long flounder (長ヒラメ) is a species of fish which has been trained and employed by the Ryugu Palace. Like a normal flounder, it is very flat, with both its eyes on the dorsal side, and it's mouth on the opposite. However, as it's name suggests, it is very long like an eel. Furthermore, it is large enough to carry several people on one side. After applying a coating bubble to the dorsal side, it is used as a platform to hold air-breathing humans while hosting events and parties in an underwater environment.
