Yes!
*Some Pokemons are based in some real life animals!
Not only animals, but plants and other things, like pre-history animals (Fossil-Pokemons).*
This is an Axolotl, if you see it looks like Wooper!
Gamefreak based this animal into Wooper.
HERE you can see the name origins for all Pokemons!
Example of Butterfree and Pidgeot -
> butterfly - a flying insect
free - without limit, now it’s able to fly
pigeon - a species of bird (based on a bird)
Hope this helps!
