Biology

Following an event of allopatric speciation, Shellos and Gastrodon have been divided into two visually different forms based on their habitat, the temperature of their water, and their diet. Normally a friendly species, they ooze a sticky fluid, thought to be a form of sweat, when bothered. They can go on land for short periods of time, but have to go back to water to keep themselves hydrated.

Forms

West Sea Shellos

West sea Shellos live in warmer water.

East Sea Shellos

East sea Shellos live in colder water.

About its forms: Forms only affect appearance. A form is determined before a wild encounter based on whether the battle is in western or eastern Sinnoh, or inherited from the mother when breeding, and cannot be changed.

Found in abundance on seashores bordering warm waters. Shellos are unexpectedly friendly and will crawl toward any person they see. Take care not to get coated in mucus!
Legends: Arceus
Subjecting this Pokémon to a strong force causes it to secrete a strange purple fluid. Though harmless, the fluid is awfully sticky.
Shield
This Pokémon’s habitat shapes its physique. According to some theories, life in warm ocean waters causes this variation to develop.
Sword
When it senses danger, a purple liquid oozes out of it. The liquid is thought to be something like greasy sweat.
Ultra Moon
While they normally live in the sea, they can function on land, too, until their skin dries out.
Ultra Sun
Purple mucus sticks to the hands of anyone who touches it. Take care, as the substance is troublesome to wash off.
Moon
For the most part, it makes its home along the seashore. Its color and form differ according to its habitat and the quality of its food.
Sun
Its shape and coloration vary, depending on its habitat.
HeartGold · SoulSilver · Y · Alpha Sapphire
Beware of pushing strongly on its squishy body, as it makes a mysterious purple fluid ooze out.
Platinum · Black · White · Black 2 · White 2 · X · Omega Ruby
It lives along bodies of water. Its body shape has changed to suit its habitat.
Pearl
Its colors and shapes differ from region to region. In the Sinnoh region, two types are confirmed.
