When it comes to describing and defining things effectively in English, a good reference is always a learner's dictionary using only English.

susan53's definition is a good example. Male lions have long hair makes me think that their fur is longer, or that female lions could have a mane, but it would be shorter. You need to include information about where that hair is. A male lion has long hair on its neck would be an acceptable description for me.

OK. I got your point, and I agree with you.
Thank you for your kind suggestion.

BTW, I'm not so clever enough to correct learner's dictionaries, and it is not the matter of language, but I wonder "mane" grows from a male lion's neck or not.

I think "mane" grows not only from neck but also from head, chin, all around his(its) face. Don't you think so?
