Barsoom is known as Mars on Earth. The inhabitents are human and identical in every way to you and me. As Barsoom has a weaker gravity than Earth, humans from Earth are able to jump higher than the natives. The planet is a desert as you would expect when you look Barsoom, ahem, Mars. There are two main races that live on the planet, humans and Tharks. Although the film doesn`t venture into it, in the book, the Barsooms don`t wear clothes except for some jewellary to protect their modesty.
