Lion

The Lion was a four-legged, carnivorous mammal. It is also a big cat. It was one of the Talking Beasts of the World of Narnia. As in our world the males are easily recognized for the mane of fur around their neck, which the females, called lionesses, lack. Young lions are generally called cubs.

Aslan the ruler over all Narnia, takes the form of a lion, and thus all lions in Narnia are treated with special respect.

There was also a lion that was a stone prisoner in the courtyard of Jadis that Edmund Pevensie mistakens as Aslan. It was restored by Aslan and carried 3 dwarves, a dryad, two rabbits, and a hedgehog to where the First Battle of Beruna was occuring.

In the movie in the scene when Mr. Tumnus attacks a Boggle, a female lion can be seen.
