The Indian long-eared hedgehog is a relatively small hedgehog (~17 cm, 200–500 grams). It is a nocturnal animal that is often found inhabiting burrows. [3] Similar to most hedgehogs it has spines on its back, embedded into a muscle sheath. This sheath forms a bag-like structure that the animal can hide inside for protection.
The Southern African hedgehog is said to be a slow mover; however, when threatened, it can move surprisingly fast at 6 to 7 km/h (3.7 to 4.3 mph). [3] During the day, they typically stay where they live, which is an area that is covered with vegetation or in a hole in the ground.
