The Family Erinaceidae refers to a group of spiny mammals that are commonly known as hedgehogs. However, there are several synonyms for this family name, including Erinaceinae, Erinaceomorpha, and Insectivora. These synonyms reflect the close evolutionary relationship between hedgehogs and other insect-eating mammals, including shrews and moles. While hedgehogs are a familiar sight in many parts of the world, they are often misunderstood and can be threatened by habitat loss and other human activities. Conservation efforts are underway to protect these unique and fascinating creatures, which play an important role in maintaining healthy ecosystems.
