People have compared the lizards to monsters, and it's not the first time the marine iguana has gotten a bad rap. Back in the 1800s, Charles Darwin referred to them in his journal as "imps of darkness ... disgusting, clumsy lizards."
But what exactly makes these herbivores so "monstrous?"
Whatever the reason people fear the marine iguana, they pose no danger to humans.
In fact, they're a little silly. Like humans, marine iguanas frequently sneeze to clear out their nostrils, except, instead of pollen, they're getting the salt out of their noses. The salt often collects on the tops of their heads, which results in something that resembles a wig.
Nevertheless, the lizard will probably still frighten a few excitable humans. The marine iguanas don't mind. They're too busy foraging for plants in their beautiful ocean home to worry about name-calling.
