Did you know?

Faunus and Fauna were the Roman woodland god and goddess for whom animals were a particular concern. Faunus was the Roman equivalent of the Greek god Pan, and like Pan, he had goats' legs. Their goat-legged helpers, called fauns, were known for their love of pleasure and mischief. The fauna of a continent are often very similar across a broad east-west band; from north to south, however, they may vary greatly.
