Pokédex entries

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

Ruby	WAILORD is the largest of all identified POKéMON up to now. This giant POKéMON swims languorously in the vast open sea, eating massive amounts of food at once with its enormous mouth.
Sapphire	When chasing prey, WAILORD herds them by leaping out of the water and making a humongous splash. It is breathtaking to see this POKéMON leaping out of the sea with others in its pod.
Emerald	It breathes through nostrils that it raises above the sea. By inhaling to its maximum capacity, a WAILORD can dive close to 10,000 feet beneath the waves.
FireRed / LeafGreen	It is among the largest of all POKéMON. It herds prey in a pack then swallows the massed prey in one gulp.
Diamond / Pearl / Platinum / Black / White / Y	The biggest of all Pokémon. It can dive to a depth of almost 10,000 feet on only one breath.
HeartGold / SoulSilver	It is the largest of all identified Pokémon. They jump as a pack to herd their prey.
Black 2 / White 2 / X	It can sometimes knock out opponents with the shock created by breaching and crashing its big body onto the water.
Omega Ruby	Wailord is the largest of all identified Pokémon up to now. This giant Pokémon swims languorously in the vast open sea, eating massive amounts of food at once with its enormous mouth.
Alpha Sapphire	When chasing prey, Wailord herds them by leaping out of the water and making a humongous splash. It is breathtaking to see this Pokémon leaping out of the sea with others in its pod.
Sun	Wailord pursue their prey in pods. With their large mouths, they can swallow entire schools of Wishiwashi whole.
Moon	Its immense size is the reason for its popularity. Wailord watching is a favorite sightseeing activity in various parts of the world.
Ultra Sun	They eat so many fish Pokémon that when Wailord become too numerous, fishermen have to chase them off.
Ultra Moon	When a small Wailmer is attacked by Sharpedo or Dhelmise, its whole pod works together to protect it.

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.
