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); Hody Jones went all the way to the North Pole to kidnap the Kraken for his uses, due to its fearsome power, he only managed to keep it under control by holding its brothers as hostage. The only seen 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. Hody also mentioned that, as a legendary creature, a Kraken can be sold for a high price, even if dead.

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

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.
