Pokédex entries

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

Red / Blue	Moves silently and stealthily. Eats the eggs of birds, such as PIDGEY and SPEAROW, whole.
Yellow / X	The older it gets, the longer it grows. At night, it wraps its long body around tree branches to rest.
Gold	It can freely de tach its jaw to swallow large prey whole. It can be come too heavy to move, however.
Silver / SoulSilver	It always hides in grass. When first born, it has no poison, so its bite is painful, but harmless.
Crystal	It flutters the tip of its tongue to seek out the scent of prey, then swallows the prey whole.
Ruby / Sapphire	EKANS curls itself up in a spiral while it rests. Assuming this position allows it to quickly respond to a threat from any direction with a glare from its upraised head.
Emerald	An EKANS curls itself up in a spiral while it rests. This position allows it to quickly respond to an enemy from any direction with a threat from its upraised head.
FireRed	A very common sight in grassland, etc. It flicks its tongue in and out to sense danger in its surroundings.
LeafGreen	Moving silently and stealthily, it eats the eggs of birds, such as PIDGEY and SPEAROW, whole.
Diamond / Pearl / Platinum / Black / White / Black 2 / White 2	It sneaks through grass without making a sound and strikes unsuspecting prey from behind.
HeartGold	It can freely detach its jaw to swallow large prey whole. It can become too heavy to move, however.
Y	Moving silently and stealthily, it eats the eggs of birds, such as Pidgey and Spearow, whole.
Omega Ruby / Alpha Sapphire	Ekans curls itself up in a spiral while it rests. Assuming this position allows it to quickly respond to a threat from any direction with a glare from its upraised head.
Ultra Sun	By dislocating its jaw, it can swallow prey larger than itself. After a meal, it curls up and rests.
Ultra Moon	The eggs of bird Pokémon are its favorite food. It swallows eggs whole, so sometimes an egg gets stuck, and Ekans faints.

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.
