Information about rare species of rats

Let's know today some of the strange information in strange animals:

1. When we grow hair, we cut it, and when the nails grow, cut the nails down. But is there a living creature whose teeth grow like a hair or a nail? Although weird to hear, Beaver, a species found in America, continues to grow in front of a special species of rats. They do not need to cut teeth like our hair or nails. Because the bivaras always cut their bark or barks with teeth, naturally their growing teeth become smaller.
   
   Researchers believe that due to the hardening of hard ribbons, the risk of tooth loss is due to the increase of teeth of beaver mice in the teeth.

2. It is possible to recognize each lion separately by looking at the stains of the lion's forearm. Because the spots are different for each lion. Meaning there is no match for a lion's hairline with another lion.

3. We all know the roar of the lion. But there is no idea how loud that sound can be and how far can it go? It will be astonishing to hear that a lion's roar of an adult is heard about eight kilometers away.
