The European hedgehog (Erinaceus europaeus) is a small, nocturnal mammal found across Europe and parts of Asia. It has a distinctive coat of spines, which serve as a defense mechanism against predators. Typically, these hedgehogs have a round body, short legs, and a pointed snout, measuring about 20 to 30 centimeters in length. Erinaceus europaeus primarily feeds on insects, worms, and small invertebrates, making it an important part of the ecosystem. They are known for their hibernation behavior, retreating to nests during colder months to conserve energy. This species is currently facing threats from habitat loss and road traffic.
