Shellder

() is a -type Pokémon introduced in Generation I. 
==Biology==
===Physiology===
Shellder is protected by its two large shells. Its large tongue is always kept hanging out. It has two large eyes inside the shell.
=== Behavior ===
Shellder live on the sea floor, digging holes with their tongues and hiding in them with their tongues out to catch prey. Their tongues are never withdrawn, even when sleeping. Yanking on them will cause them to open up in shock. Shellder can move surprisingly quickly by flapping their shells. They can also lampoon prey with Icicle Spear.Shellder enjoy eating Slowpoke tail secretions and will bite these tails on sight. They then adopt a spiral shape and inject poison as the Slowpoke evolve into Slowbro. They are also oddly attracted to King’s Rocks. If a Slowpoke is wearing one, a Shellder may propel itself into the air to bite its head, triggering its evolution into a Slowking.
===Natural abilities===
Shellder can have the ability Shell Armor or the ability Skill Link. Shell Armor prevents Shellder's opponents from getting a Critical Hit on Shellder. Skill Link increases the frequency of multi-hitting attacks. As a last resort, Shellder clamps on to its opponents. It swims backward by opening and closing its two shells.
It is said (in the anime & in-game Pokédex entries) that if a Shellder clamps onto a Slowpoke's tail, the Slowpoke will evolve into Slowbro (the Shellder changes shape with it). Also if a Shellder clamps on Slowpoke's head while wearing a King's Rock, the Slowpoke will evolve into a Slowking. According to Slowking's Pokédex entries, when the Slowpoke's head is bitten, toxins enter the Slowpoke's head (and into its brain), unlocking extraordinary power and triggering evolution. These same toxins also causes a Slowbro to no longer be able to feel pain. 
According to Slowbro & Slowking's Pokédex entries, the Shellder's produce toxins that affect either their victims brain (in Slowking's case) or their nervous system (in Slowbro's case). It is also said that if a Slowbro's or Slowking's Shellder is removed or detached it (Slowbro/Slowking) will revert (devolve) back to a regular Slowpoke.
Also, it is said that Shellder's tend to latch on to a Slowpoke if it is holding a King's Rock (a reference to Slowking's requirements for evolving).
Upon the Slowpoke's evolution, the Shellder changes it form into either Slowbro's shell (attached to Slowbro's tail) or a Slowking's crown. In its crown form, the Shellder eyes are located on it backside (which can be easily seen by the player character when a Slowking is used in battle), basically giving Slowking eyes in the back of its head.
Shellder are known to be prey for many Pokémon such as Kingler, which use their giant claws, Omastar, which use their fangs, Rufflet, which use their talons, and Bruxish, which use their teeth all to crack open its shell.
==Evolution==
Shellder evolves into Cloyster by use of a Water Stone.

===Origin===
It is based off of a bivalve clam with its tongue representing the "foot" of a clam (a part of a clam often mistaken for a tongue). The fact it bites onto Slowpoke and produces toxins into them may make it based off of a leech as well.
===Etymology===
Shellder is a mix of shell or shelled and shelter.
