Pokédex entries

What each game says about it, in the games' own words.

Red / Blue / LeafGreen / X	Its hard shell repels any kind of attack. It is vulnerable only when its shell is open.
Yellow	The shell can withstand any attack. However, when it is open, the tender body is exposed.
Gold	It swims facing backward by open ing and closing its two-piece shell. It is surprisingly fast.
Silver / SoulSilver	Grains of sand trapped in its shells mix with its body fluids to form beautiful pearls.
Crystal / Y	Clamping on to an opponent reveals its vulnerable parts, so it uses this move only as a last resort.
Ruby / Sapphire	At night, this POKéMON uses its broad tongue to burrow a hole in the seafloor sand and then sleep in it. While it is sleeping, SHELLDER closes its shell, but leaves its tongue hanging out.
Emerald	At night, it burrows a hole in the seafloor with its broad tongue to make a place to sleep. While asleep, it closes its shell, but leaves its tongue hanging out.
FireRed	It is encased in a shell that is harder than diamond. Inside, however, it is surprisingly tender.
Diamond / Pearl / Platinum / Black / White / Black 2 / White 2	It swims backward by opening and closing its two shells. Its large tongue is always kept hanging out.
HeartGold	It swims facing backward by opening and closing its two-piece shell. It is surprisingly fast.
Omega Ruby / Alpha Sapphire	At night, this Pokémon uses its broad tongue to burrow a hole in the seafloor sand and then sleep in it. While it is sleeping, Shellder closes its shell, but leaves its tongue hanging out.
Sun	The hardness of its shell surpasses the hardness of a diamond. In days gone by, people used the shells to make shields.
Moon	This Pokémon’s tongue is always hanging out. It uses its tongue with great dexterity to dig up sand from the seabed in its search for food.
Ultra Sun	The sand that accumulates inside its shell eventually becomes a pearl. But the pearl gets in the way, so it spits it out and discards it.
Ultra Moon	Even when its shell is closed, its tongue still hangs out. If you give its tongue a good yank, the shock will cause Shellder to open its shell.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
