This post has the same exact title, but it is not related in any way apart from the fact that it is also a riddle; all my riddles are (hopefully) original and created by me.
Riddle me this:
We are either black with white,
Or we are white with black.
The latter is believed despite,
The skin our coats set back.
Our patterns are a fingerprint,
Though we have not one hand.
In zig-zags we will always sprint,
With zeal that names our band.
We can be found where Nile lives,
Especially the wild.
In the movie, king forgives,
And Marty reconciled.
Our favourite shapes include a stripe,
Where lions think of grass.
If we did not remain our type,
We all could not bypass.
What are we?
A little hint:
A plural or non-plural answer is acceptable, I am not too fussed. I mean, I like to have a balanced mindset, a bit like the Yin and Yang.
The title is also a clue.
