It has proteroglyph dentition,meaning it has two short,fixed fangs in the front of the mouth which channel venom into the prey like hypodermic needles.The male is larger and thicker than the female. It lives in dense highland forests.The snake has a preference for living in areas dotted with lakes and streams.King Cobra populations have dropped in some areas of its range due to the destruction of forests,but despite this the snake. King Cobra's venom is primarily neurotoxic and thus attacks the victim's central nervous system and quickly induces severe pain, blurred vision,vertigo,drowsiness,and paralysis.

During a bite, venom is forced through the snake's 1.25 to 1.5 centimeters (0.49 to 0.59 in) fangs into the wound, and the toxins begin to attack the victim's central nervous system. Symptoms may include severe pain, blurred vision, vertigo, drowsiness, and paralysis. Envenomation progresses to cardiovascular collapse, and the victim falls into a coma.
king cobra is unusual among snakes in that the female king cobra is a very dedicated parent. She makes a nest for her eggs, scraping up leaves and other debris into a mound in which to deposit them, and remains in the nest until the young hatch.
A female usually deposits 20 to 40 eggs into the mound, which acts as an incubator. She stays with the eggs and guards the mound tenaciously, rearing up into a threat display if any large animal gets too close, for roughly 60 to 90 days.
Inside the mound the eggs are incubated at a steady 28 °C (82 °F). When the eggs start to hatch, instinct causes the female to leave the nest and find prey to eat so she does not eat her young.

Armadillos are the only living mammals that wear such shells.Closely related to anteaters and sloths, armadillos generally have a pointy or shovel-shaped snout and small eyes. They vary widely in size and color, from the 6-inch-long (15-centimeter-long), salmon-colored pink fairy armadillo to the 5-foot-long (1.5-meter-long), dark-brown giant armadillos.
They have very poor eyesight, and utilize their keen sense of smell to hunt. Strong legs and huge front claws are used for digging, and long, sticky tongues for extracting ants and termites from their tunnels. In addition to bugs, armadillos eat small vertebrates, plants, and some fruit, as well as the occasional carrion meal.
In the mating grasp, or amplexus, the male rides on top of the female, grasping her with his forelimbs posterior to her forelimbs. The female bullfrog deposits her eggs in the water and the male simultaneously releases sperm.
Breeding begins in late spring or early summer. Males defend and call from territories, attracting females into a territory to mate. The call is reminiscent of the roar of a bull, hence the frog's common name. A female may produce up to 20,000 eggs in one clutch.
