For the full list of Pokémon, see Pokédex.
Pokédex entries typically describe a Pokémon in only two or three sentences. They may give background information on the habitat or activities of a Pokémon in the wild, or other information on the Pokémon's history or anatomy. Pokédex entries also include height and weight, cry, footprint, location, the Pokémon's sprite, and possibly more.
The current interface (the UI) is the default one that comes with Pokémon Essentials.
