Underworld of the Sea in One Piece

Nothing is known about this area located at the depths of the ocean. Some abnormal creatures are known to exist here, and it is difficult to see anything through this area unless one has a special lens or in case of sea creatures, is bioluminescent.

The Straw Hat Pirates traveled through this area, while they were en route to Fishman Island.

There are numerous creatures living in the deep seas. Some of those are listed below:

Kraken

Kraken is an enormous, octopus-like creature that has no bones. Between its arms is a head that resembles a turtle without a beak. It is sometimes referred to as the "Monster of the Arctic."

Carnivorous tubeworms

Carnivorous tubeworms are large, predatory worms. They display hostile behavior.

Anglerfish

Anglerfish are gigantic fish residing in the deep sea. They try to devour ships or creatures passing through their way.

Blobfish

Blobfish living in the deep seas are harmless creatures. They don’t appear to be predatory, unlike other deep sea creatures.

Flatface Crab

Flatface crabs are creatures that appear to have no eyes. They are extremely aggressive and dangerous.

So far, all the species we've seen are enormous copies of critters that can be found in deep water in the real world.
