Shellos (Japanese: カラナクシ Karanakushi) is a Water-type Pokémon introduced in Generation IV.

It evolves into Gastrodon starting at level 30.

Shellos have two different appearances: West Sea (pink and white) and East Sea (blue and green), found on the respective sides of Sinnoh's mountain range.

Biology

Shellos is a sea slug-like Pokémon whose appearance changes drastically depending on the sea it is found in. However, both forms have amorphous, slug-like bodies. Like real sea slugs, they have mantles covering the top halves of their bodies. Unlike real sea slugs, they have bulbous heads and four small feet rather than one large foot. Both forms also have black oval-shaped eyes, tiny noses, wide yellow lips, and yellow outlines around their eyes and mantles.

In the West Sea form, the underside is white and the mantle is pink. The mantle has several small spike-like protrusions on it. On its head is a ring of pink fleshy knobs resembling the gills of a nudibranch.

In the East Sea form, the underside is green and the mantle is blue. The shell has two flap-like protrusions, resembling cerata. These protrusions are lined with yellow. On its head are two white-tipped tentacles resembling rhinophores that extend away from its face.

The Nurse Joy featured in Gateway to Ruin! revealed Mount Coronet's formation led to the allopatric speciation event, with the original population of Shellos being separated into two. As a result, Shellos' color and other physical differences began to vary due to environmental differences and population isolation over time. West Sea Shellos' appearance is theorized to have been influenced by warm ocean waters, while East Sea Shellos is believed to have been influenced by cold ocean waters. It is also believed that diet influences a Shellos' form, but this has yet to be proven. The two forms are still able to interbreed; the child takes the mother's form or the father's if bred with a Ditto. If Shellos is pushed or squeezed, a mysterious purple fluid, said to be sticky and similar to greasy sweat, will ooze out of its body. In the anime, West Sea Shellos can extend their necks to incredible lengths. It is unknown if the East Sea form can do this as well. Shellos live along the seashore. They are said to have great regenerative capabilities. The species’ diet consists of plankton. Shellos can live on land or in the sea, though its skin dries out if it stays on land for too long.

Trivia

Shellos's early back sprite

• According to an interview in Nintendo Power with Game Freak, Shellos and Gastrodon were originally intended for Pokémon Ruby and Sapphire.^[1]
• Both Shellos and Gastrodon have early back sprites that can be found in the game data for Pokémon Diamond and Pearl; however, there are no front sprites for these forms.
• In Diamond and Pearl, no in-game Trainer uses East Sea Shellos in battle, even on the east side of Mount Coronet.
• Shellos's English Pokédex entry for Pokémon HeartGold and SoulSilver has the fewest words of any Pokédex entry in the core series games, with nine. The Pokédex entry is carried over to Pokémon Y and Pokémon Alpha Sapphire.
  • The same is true for Kyurem in White.
• Prior to Generation VI, Shellos's shape was .
• Shellos and its evolution were accidentally released in Pokémon GO on April 29, 2019, but were removed shortly after. On May 17, 2019, they made their official debut along with various other Pokémon from Generation IV.
• Shellos is the only Pokémon with Sand Force that benefits from its sandstorm immunity, since every other Pokémon with the Ability are naturally immune to sandstorm damage due to their typing.

Origin

Shellos is based on a sea slug. It resembles various species of nudibranchs, and its ability to secrete purple fluid may be based on sea hares, most of which secrete a purplish ink for self-defense.

Name origin

Shellos may be a combination of shell and loss or lost (referring to its lack of a shell), or the German suffix -los (-less).

Karanakushi is a combination of 殻 kara (shell) and 無くした nakushita (to have lost) or 無し nashi (without).
