From Bulbapedia, the community-driven Pokémon encyclopedia.
The Water 1 Egg Group (Japanese: すいちゅう1 Underwater 1) is one of the fifteen Egg Groups. Like its counterparts Water 2 and Water 3, it is mostly made up of Water-type Pokémon. As of Generation VI, 89 Pokémon belong to this group.
Characteristics
Water 1 group Pokémon tend to be mostly terrestrial Water-type Pokémon, with few fishlike Water types among them. Most are capable of both land-based and aquatic locomotion. It can be thought of as being similar to the Field Group in that it is a "catch-all" Egg Group for aquatic and semi-aquatic animals.
The majority of Pokémon within this Egg Group are capable of breeding with Pokémon of other Egg Groups.
