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 slug-like Pokémon whose appearance changes drastically depending on where it is found. However, both forms have a shell-like back and an amorphous lower body. Both forms also have yellow lining around their eyes, mouth, and back.

In the West Sea form, the underside is white and its shell is pink. The shell has several small spike-like protrusions on it. On its head is a ring of pink fleshy knobs resembling flower petals that spike up.

In the East Sea form, the underside is green and its shell is blue. The shell has two flap-like protrusions. These flaps are lined in yellow. On its head are two white-tipped knobs resembling horns that extend away from its face.

The Nurse Joy featured in Gateway to Ruin! revealed Mt. 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. 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 it is pushed or squeezed, a mysterious purple fluid 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 sea shore.

West Sea Shellos in Pokémon Adventures

East Sea Shellos debuted in Bombastic Bibarel & Heroic Hippopotas, under the ownership of a male Ace Trainer seen at the Seven Stars Restaurant.

Shellos's most notable appearance is that of a companion of Mr. Fuego's. He typically keeps his East Sea Shellos on his shoulder, continuing to do so even after he accidentally imprisoned himself to avoid Team Galactic. It first appeared in Maddening Magby.

West Sea Shellos debuted in Movie Panic, where it was at the Pokéstar Studios, presumably under the ownership of one of the visiting Trainers from the Aspertia Trainers' School.

Sun Shellos lives in the sea and feasts on plankton. The lovelier the ocean where Shellos resides, the more vibrant its color becomes.
Moon The difference in color from one Shellos to another seems to be a result of their diet. No large changes can be seen in their capabilities.
Ultra Sun When it senses danger, it gushes a purple liquid. Some theories suggest this liquid is a greasy sweat induced by stress.
Ultra Moon Scientists interested in its great regenerative capabilities are currently analyzing the materials from which its cells are made.

Sword There's speculation that its appearance is determined by what it eats, but the truth remains elusive.
Shield Its appearance changes depending on the environment. One theory suggests that living in cold seas causes Shellos to take on this form.
