Gastrodon (Japanese: トリトドン Tritodon) is a dual-type Water/Ground Pokémon.

It evolves from Shellos starting at level 30.

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

Biology

Physiology

Gastrodon is a Pokémon based on a sea slug, and appears much the same as its pre-evolution, but it gains six visible but stubby legs and is noticeably larger. They both additionally have plain black eyes with white irses, with a third eye in the center of their forehead. Like Shellos, Gastrodon has two forms;

In the West Sea form, the flower-like crest it had as a Shellos has now turned into horns adorning the side of its head, which point directly upwards in a crescent moon shape. Its underside up to the bottom of its mouth is pink, its back and the top of its head is completely brown, and it has two with small protrusions on its back with several pink spots dotted around them. It also has two small protrusions on its neck underneath the horns, and it has a yellow border running down its body from its head, separating the brown and the pink coloration.

In the East Sea form, it retains the horns it had as a Shellos, although now fully colored green which point at a 45 degree angle. Its underside up to the bottom of its mouth is blue, its back and the top of its head is completely green, and it has two yellow "fins" adorned on its back with a third bordering its side and rear, as well as two small blue spots between them. It has a yellow border running down its body from its head, separating the blue and the green coloration.

Gastrodon and its pre-evolution Shellos are examples of allopatric speciation, though they are still able to breed.

Gender differences

None.

Special abilities

If any part of a Gastrodon's boneless body is ever ripped or torn off, it can grow back in very little time.

Behavior

When its natural enemy attacks, it oozes purple fluid and escapes.

Trivia

Early back sprite of Gastrodon

• According to an interview in Nintendo Power with Ken Sugimori, Shellos and Gastrodon were originally intended for Pokémon Ruby and Sapphire, but were not implemented due to time constraints.
  • Both Shellos and Gastrodon have an early back sprite within the game data; however, there are no front sprites for these forms.
  • These earlier forms both are similar to the pink, West Sea variations of Shellos and Gastrodon, possibly meaning that they were developed from the Generation III versions.
• In Pokémon Diamond and Pearl, no in-game Trainer uses East Sea Gastrodon in battle, even if the Trainer's current location is east of Mt. Coronet. This changes in Pokémon Platinum.

Origin

Gastrodon is based on a sea slug, perhaps specifically that in the order, Opisthobranchia. The East Sea Gastrodon seems to be based on a Sea Hare.

Name origin

Gastrodon is a combination of gastropod and don (Spanish for lord). It may also derive from Gastropteron, a species of sea slug.

Tritodon is a combination of from Tritoniidae or Triton (referring to either the aquatic Greek god or the common name of the gastropod genus Charonia) and don. It may also involve the word torito (Spanish for little bull, referring to its appearance).
