Why do some lizards and snakes have horns on their heads?

Belgium: Horns are not only unique to rhinoceros and cattle, but you may have seen them on the heads of many snakes and lizards, but why?
According to a report published by the researchers in Biology Letters, the majority of horned lizards and snakes wait for their prey rather than chasing it.
According to scientists, horns probably help most stationary animals hide in their surroundings, but can be detrimental to more mobile ones because they may signal the animal’s presence to prey and predators. are
Previous studies have shown that in ancient times, snakes and lizards may have used horns for various purposes such as mating, defense or to deceive other animals due to their physical appearance.
“Antlers are a blessing for some species but a burden for others,” said Federico Banfi, a researcher at the University of Antwerp in Belgium.
Animals that move a lot, he said, can suffer from having horns on their heads. This makes them more conspicuous to prey and predators as the horn makes their head look bigger which makes them easier to spot by other predators.
