What kind of real life animal doesnt have a pokemon version yet ?

So, some time ago i was thinking about cool ideas for new pokemon and i realized that most popular and recognizable animals in real life already have a pokemon associated with them, so i became fascinated with this conundrum of trying to figure out which ones do not have a pokemon yet.

Initially i thought about camels and mosquitos but then i remembered Camerupt and Buzzwole, and so far the only animals i know without a pkmn are dolphins and capybaras.

Anyone knows another animals ?
