Which mole is venomous? How does this help the animal?

One common belief about European moles is that they typically consume their own weight in food every 24 hours, but this is an exaggeration. Studies have been performed that show European moles eat about half of their body weight in food each day. When in captivity, European moles will eat a wide variety of food items, including liver, mice, mealworms, shrews and maggots. However, they tend to prefer earthworms over all other options. In areas without as many earthworms, insects are the main dietary constituent. Moles eat both larval and adult insects.
