The hedgehog's back contains two large muscles that control the position of the quills. The average hedgehog has about 5,000 to 6,500 quills that are strong on the outer surface but filled with air pockets on the inside. When the creature is rolled into a ball, the quills on the back protect the tucked head, feet, and belly, which are not quilled.
When under extreme stress or during sickness, a hedgehog can also lose its spines. Their under-parts are covered by coarse grey-brown fur, forming long skirts along flanks. A hedgehog measures around 23 centimetres in length and has a 4 centimetre tail.They can weigh up to 2 kilograms.heir spines are not poisonous or barbed and unlike the quills of a porcupine, cannot easily be removed from the animal. However, spines normally come out when a hedgehog sheds baby spines and replaces them with adult spines.
