A Jungle World is not an official Imperial planetological classification, but is a term in common usage among Imperial citizens for those planets whose environments are a single, globe-spanning jungle across their entire surfaces. Since the term "Jungle World" is not an official Imperial classification of the Administratum but simply a label used to describe the planet's predominant environmental feature, most Jungle Worlds that have been settled by Mankind are officially classified as Death Worlds, as the environmental conditions or extant jungle biosphere are usually extremely hostile and inamicable to human life.
