A lizard.
Herpetophobia (Ancient Greek: ἑρπετόν herpetón, creeping animal and φόβος phóbos, fear) is a specific phobia, fear of reptiles, amphibians and other similar animals, more generally: creeping, creeping things. A special case of this is ophidiofobia, fear of snakes, which is sometimes also referred to as the more common term herpetophobia. The fear of reptiles in general and for snakes, in particular, seems fundamental and inherited from the time when snakes and other reptiles formed a major threat to human existence.
