did you mean concatenate? because you don't do any concatenation...
any time you hear keeping a data element with some information
associated, you should be thinking a dictionary data type, though
there's nothing wrong with having a data element be a list or a tuple
either, and we don't know if you have some specific requirements that
are not showing here.

If you want a dictionary, you can try this one-liner:
animalinfo = { animal: len(animal) for animal in animals }
print(animalinfo)
