After Man: A Zoology of The Future/YMMV
- Artistic License Biology: WAAAY too many examples to count.
- Ensemble Darkhorse: The Night Stalker is no doubt the most famous creature in the book.
- Fan Dumb: Many people keep saying that the Mud-Gulper is evolved from a hippopotamus, even though the book CLEARLY said that it's derived from a water-dwelling rodent, and evolved parallel to a hippopotamus.
- Germans Love David Hasselhoff: Just like The Future Is Wild, Japan loves it.
- Nightmare Fuel: The Night Stalker qualifies.
- The Chiselhead anyone?
