aka: The Jungle Opera
This is a speculative tale that takes place in undiscovered or semidiscovered country in the present or "recent" (usually no earlier than the early 20th century) past supposedly on this Earth. As opposed to say a High Fantasy in a Medieval setting, or a Space Opera in a far future-like setting. As the title indicates it often takes place in a tropical rain forest though that is not necessary. The key point is that Willing Suspension of Disbelief is provided primarily by the use of settings that are regarded as exotic, mysterious, dangerous and above all, far away by most readers, yet still on this world; rather then providing a whole imaginary world "in a galaxy far away". A typical setting for instance, might be The Amazon, Darkest Africa, or The Shangri-La . There are occasional similarities with the Space Opera, the two genres can each borrow tropes normally associated with each other and there is potential for crossovers (aliens can for instance kidnap the intrepid explorers, or perhaps a Space Opera can have a story take place on a jungle planet). However some elements of a Jungle Opera can be less flexible then other speculative sub-genres by the nature of operating in "closer proximity" (so to speak) to Real Life. Jungle Operas tend to feature Bold Explorers, primitive locals, Precursors, Lost Colonies, Ancient Artifacts, and the like; ruins-filled-with-deathtraps is one of The Oldest Ones in the Book. This will also likely involve Ancient Astronauts and have an Adventurer Archaeologist as one or more of the characters. Oddly enough the experiences of Real Life explorers did sometimes have a suspicious resemblance to this genre. We don't think that any secrets man was not meant to know have been discovered — not that anyone would admit it if there have been some. Maybe the world was not yet ready? Often involves a Lost World. In some versions the story is about a quest to find this, and a Lost World is a MacGuffin Location.
- Tintin had this every once in a while (Tintin in the Congo, Cigars of the Pharoah, Prisoners of the Sun) but Flight 714 has this with a twist: Ancient Astronauts.
- The Marsupilami lives in the jungles of Palombia and the comics often feature the native indian tribe, a Great White Hunter, and foreign documentary filmmakers and industial investors entering its wild world.

- The Serpent, the first novel in Jane Gaskell's Atlan series, takes place in a prehistoric civilization in ancient South America and contains such elements as giant carnivorous birds and a reptile-man villain. The rest of the saga is in the vein of a Lost World but is still rife with jungle hijinks, particularly in The City, in which the heroine returns to her former home.
