Cobras are famous for the threatening hood at their neck. They spread the hood out when they feel threatened or angry. Their hood is made up of flaps of skin attached to long ribs. They are also able to lift their heads high up off the ground, which is not only kinda scary, but helps them to search for food. And just to make them a little scarier, they hiss loudly to scare off potential predators.
There are 270 different types of Cobras and their relatives, including Taipans, Adders, Mambas, and many sea snakes including Kraits, and they all have short fangs and are all extremely poisonous.
