These are affected by a variety of things, such as level, Effort Values (EVs), Individual Values (IVs), and Shellder's Nature.By default, the stats you see in the table below show four different possibilities, all assuming Shellder is level 100: its stats with 0 EVs, 252+ (max) EVs, 0 IVs, and 31 (max) IVs. Nature is not shown by default, so its maximum is 10% higher than shown here, and minium 10% lower.

Generation 8 Pokédex Entries
Sword It swims facing backward by opening and closing its two-piece shell. It is surprisingly fast. Shield Its hard shell repels any kind of attack. It is vulnerable only when its shell is open.
Generation 7 Pokédex Entries
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.
Generation 6 Pokédex Entries
X Its hard shell repels any kind of attack. It is vulnerable only when its shell is open. Y Clamping on to an opponent reveals its vulnerable parts, so it uses this move only as a last resort.

While it is sleeping, Shellder closes its shell, but leaves its tongue hanging out.
