This is a series of short articles explaining common mistakes writers make about animals and giving cool facts about animals that might be useful for writers. Anyone who's interested in animals may also find this series interesting. Let me know what you think.
No matter how fond some authors are of describing them otherwise, reptiles are not slimy. Snakes, lizards, turtles, alligators, and other reptiles are scaly and rough and dry, not smooth and covered in slime. Your hero is not going to encounter “slimy snakes” unless the snakes happen to be slithering through something slimy. If a reptile is slimy, it is due to living in a wet environment and not because it secretes slime like an amphibian.
