Animal Species

Den Den Mushi
These are the odd "phone snails" that are used throughout the series. They come in a variety of colors and shapes and have multiple functions. The snails act as a number of devices including: rotary phones, fax machines, and cellular wrist watch devices. It's unknown how the Den Den Mushi are able to communicate with one another over such great distances. When they are used, the snails speak in sync with the caller's voice, as well as sometimes imitating the facial expressions of the caller. Fans have speculated that the snails may be naturally telepathic, and somehow this ability has been harnassed in lieu of wireless phone technology in the One Piece world. When not in use, the Den Den Mushi are usually inert, either sleeping or in a dazed state. Other types of Den Den Mushi include:

Kuro Den Den Mushi
A (Black) Den Den Mushi, is used by the Navy to intercept calls between pirates or other miscreants.

Baby Den Den Mushi
The Baby Den Den mushi is fairly small and portable, but incapable of international calls.

Golden Den Den Mushi
This Den Den Mushi is a special kind that is used to summon the Buster Call.

Silver Den Den Mushi
The Silver Den Den Mushi is like an alarm used to receive the Golden one's Buster Call request.

Sea King
Sea Kings are mythical sea creatures in the anime and manga One Piece, which are generally much larger than normal sea creatures. They are found in great numbers along the Calm Belt around the Grand Line, although in rare occasions they can be found in other places throughout the world.

Sea Kings make trade and travel difficult for anyone trying to cross the water where they are found. Cases have arisen where some islands in the Grand Line close to the edge of the Calm belt have ended up getting almost completely cut off from the rest of the world. In Water 7 and its surrounding islands, this led to the eventual creatation of the Sea Train as a means to travel safely to and from each of its surrounding islands.

Sea Kings are serpent-like in appearance however they vary form one Sea King to another in exact appearance along with their size. Only the strongest of ships or captains can take on a Sea King. Most other creatures in the ocean fear the sea King and confrontation with one by all but a few humans is unadvisable. Many characters such as Franky see the act of killing one a sign of strength and achievement.

The Sea King that ate Shanks' arm is known as The Lord of the Coast.

Blue-Finned elephant Tuna
(Titanic Tuna in the English dub): A fish that comes from the South Blue and has elephant-like features. It is known as 'the jewel of the sea' it is supposed to be a miracle ingredient for cooking. It is not found in the East Blue.

Island Whales
The largest whale species in the One Piece world. They come from the West Blue. They normally swim together with other Island Whales in pods (just like real life whales) but may adopt another family (E.g. Laboon adopted a pirate ship as his pod) and swim with them.

Kestia
A type of tick that inhabits hot, humid jungles and carries bacteria in its bite. Once bitten an infection forms and after 5 days the infection begins to spread, causing the victim to experience intense pain. During this time, the victim’s temperature rises up to 40°c causing Myocarditis, Ateritis and Encephalitis. After the full 5 days of infection, the patient apparently dies. It takes 10 days after treatment to recover from the diease. While the Straw Hat Pirates were on Little Garden, Nami is bitten by a Kestia causing her to become sick. Kestia was supposed to have become extinct 100 years ago, but it survived on Little Garden because of its prehistoric setting. In the 4Kids dub the whole of Little Garden was removed, but oddly kept the part about the Kestia or "Stingy-Dingy Bug".

Giant Goldfish
Giant Goldfish is an enormous fish that haunts the sea around of Little Garden. It's known as "Island Eater" and its feces is so big that is known as "Nothing Island". This is another of Usopp's lies becoming true. This fish ate Going Merry, when Straw Hats were leaving Little Garden, but was killed by Dorry & Brogy, with their strongest attack, Hakoku, saving their friends' lifes.

Hiking Bear
A giant white bear from Drum Island known as a mountain climber. The usual manner in dealing with one is just to bow to it as a respectable mountain climber and leave it be. In the English dub, Zoro describes them as "Bipolar Bears."
