Plants usually protect the goodness inside their seeds with very hard outer cases. The reward for breaking through these cases is a protein-rich kernel, and all rodents from the tiniest harvest mice to the mighty beaver, have these special, constantly growing inscisor teeth, with chisel sharp enamel on their front edges, in order to get at food of this kind. Many rodents, like squirrels, carry away excess nuts one by one to bury them for eating later on. Some rodents use their special front teeth to chop off vegetation or chew bark instead.
