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.
The average litter is 4 â 7 newborns for larger species of hedgehog and 5 â 6 for smaller ones. The pale-coloured soft spines appear hours after birth and take 3 weeks to harden. Hedgehogs are born blind. Many believe that they are born without quills, which develop in the following days.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.
