No. These creatures don’t spit venom.
The idea that these reptiles are venomous likely came from a dinosaur called the dilophosaurus in the movie, Jurassic Park. This dinosaur looked a lot like a frilled lizard, and it was poisonous. After raising its neck frill, the dilophosaurus would spit venom. Though these two reptiles look a lot alike, the frilled lizard isn’t poisonous.
