Yes, many lizard species do eat earthworms. Lizards are generally carnivorous or insectivorous and have a diverse diet that can include a variety of invertebrates. Earthworms are a good source of protein and other nutrients, making them a suitable food option for lizards.
Different lizard species may prefer different types of prey, but those that hunt or forage on the ground often come across earthworms. For example, species like the skink and some types of geckos have been known to consume earthworms when available in their habitat.
These reptiles have a specialized feeding mechanism that allows them to swallow prey that is often larger than their heads. Their sticky tongues help them capture slippery earthworms effectively.
In conclusion, while not all lizards may actively seek out earthworms, it is certainly a common item on the menu for many lizard species, contributing to their varied diet.
