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

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

Gastrodon is a sea slug-like Pokémon. Much like its pre-evolved form, it has a slug-like body with a round head and a mantle covering the top half of its body. It has six stubby legs and three black eyes with white irises. A yellow stripe runs along the edge of its mantle, through its lower two eyes, and around the back of its head. Like Shellos, Gastrodon has two forms based on the sea it lives in.

In its West Sea form, it has a pair of large tentacles on its head that curve upward, as well as a smaller, straighter pair of tentacles on its neck. Its underside is pink, while its mantle is brown with three pink spots on each side. There are two lumps on its back, resembling the cerata on real-life sea slugs.

In its East Sea form, it retains the head tentacles it had as a Shellos, which are now fully green and angled slightly more upward. Its underside is blue, while its mantle is green with two blue spots on each side. It has a pair of yellow, fin-like cerata on its back and a wavy yellow line bordering its side and rear.

Gastrodon and its pre-evolution Shellos are examples of allopatric speciation, though they are still able to breed. It is also a relative of Shellder and Cloyster. When it is threatened, it oozes purple fluid and flees. Gastrodon lives in shallow tidal pools. Its body is soft and squishy, yet surprisingly resilient. It has strong regenerative capabilities that allow it to recover from injures within a few hours. Its diet consists mainly of plankton, but it is occasionally known to look for food on land, leaving behind a trail of sticky slime. However, Gastrodon cannot stay on land for too long due to its body being highly vulnerable to dehydration. In ancient times, it had a shell on its back, which gradually became a thin yet hard vestigial plate.

Origin

Gastrodon is based on a sea slug, perhaps one of the order Opisthobranchia. It may also be based on a sea hare, a type of sea slug that is also known to secrete purple fluid in self-defense.

Name origin

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

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