[简答题] The Armadillo (犰狳) is a very different creature. It has tremendous claws, but no fighting instinct. They have teeth, but not in front, except for the milk teeth some have during infancy. They have long tongues because they catch insects. A strange thing which these animals have is a coat armor, unique among other animals. They have bony plate armor on the outside of their bodies. Each species has a different pattern for every little plate they carry. They all are great burrowers (洞穴动物). They sink a hole with them in it as one approaches. It takes a good man to haul even a little one back if it is halfway down its retreat under the ground.
They are active, running with a tiptoe trot. Their trot is as an aged pony that is tired. They have a varied diet. They hunt by night.
Today’’s Armadillos are not the biggest armadillos that have ever existed. The soil of South America is full of larger Armadillo bones from the past. Some of the past bones were as much as sixteen feet lo
