All pets in Realm belong to a specific family. The family of the pet determines its chance to get certain abilities and the possible skins of the pet. Additionally, pets can be fused only if they are in the same family. Pet fusion also can change the family of your pet.
In terms of pet skins - Common and Uncommon ones have the same skin, Legendary pets are larger versions of Rare ones and the Divine pets have separate skins.
Here's a list of pet families, their eggs and the respective skins:
