Animal Species/Dressrosa 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 known example of a Kraken is Surume, who was introduced in Chapter 604.

In Norse mythology, the Kraken is said to have dragged dozens of sailing vessels down into the ocean to devour its crew. Indeed, 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.

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 on Ryugu Kingdom. It is a visual pun on real-life "sea lions".

Sea Giraffe
This is still an unnamed hugh sea monster that resembles a giraffe. This monster 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 Hodi and some of the New Fishman Pirates members during their attack on Ryugu Kingdom.
