There are no teeth in its jaws, but in their 

 place are horny ridges that serve instead. It 

 is a quiet timid creature, but when teazed or 

 disturbed will roll itself into the shape of a 

 ball, and then the spines only can be seen, 

 and as they are very sharp and strong they 

 serve to shield it from harm. Its long sharp 

 claws are well fitted for burrowing, which it 

 does with wonderful rapidity, especially if the 

 soil is loose or porous.
