The structural adaptations of the king cobra include its hood, its colors, its size, its fangs, and its forked tongue. The hood is an adaptation because it flares out when it's about to attack. This warns predators and signals them that he is mad and that they need to stay away. The king cobra also flares out its hood to attract mates. The king cobra's colors serve as an adaptation because they are usually a beige, black, olive green, or faint brown. These colors help the snake to blend in with its environment so it can sneak attack, to catch its prey. Size is also a structural adaptation. The king cobra can reach up to 18 feet in length. Their large size intimidates other animals and, like the hood, signals other animals to stay away. The king cobra's long fangs help it adapt by giving it the ability to tear open its prey. It makes it easier for it to eat. The fangs also help push the food into the stomach. As shown in the picture above, the king cobra has a long, narrow forked tongue. When you see its tongue sticking out, it's actually smelling the air to try to detect food.
