Erinaceidae; The Hedgehog Family
Only one species in this family resides in the UK though in mainland Europe others exist such as the eastern hedgehog (Erinaceus concolor) in eastern Europe (to differentiate this species from the other European hedgehog (E. europaeus) they are named 'eastern' and 'western' but in the UK no such clarification is needed) and the Algerian hedgehog (Atelerix algirus) which has been sighted in a handful of locations but primarily in Spain; these are considered human introductions as its ordinary range is north west Africa.
