Cobras are among the best-known snakes. It's a reptile. It is very dangerous, because it has poison in the teeth. They say, a large king cobra has enough poison in one bite to kill 20 human beings or an elephant. 
The Cobra is famous for its hood, which is formed when a snake gets angry and is ready to attack. 
Cobras can be found mainly in Africa and Asia. They typically live in hot, tropical areas.They like to spend time underground, under rocks and in trees.
They come in different colours: yellow, brown and black. Cobras eatmice, rats, rabbits, lizards, snakes, eggs and birds, but they can easely live without eating for days or months. 
Like other snakes, cobras  do not hear, they are death, but they cansense the ground vibrations.
Cobras lay eggs. They build nests for their eggs and guard them very carefully until babies are born.
It's interesting to know that cobras smell their prey using their tongue.
