How do I find out the special names that certain creatures bear?

[Ungod]

I've heard there are some creatures that have specific skills if named in a certain way.

[Muratus del Mur]

I heard the Grasan can be named certain ways and depending on that it will produce different things. (sorry this does not answer your question directly as it would be too much of a spoiler, but just confirms its so)

Ps: Pls dont post the names, just tell where to find them.
