Albino King Cobra – White King Cobra

  • The animals with leucism partially lose the pigmentation and have the pale, white, or patchy color of skin, scales, or feathers but have normal eyes.

  • Albino and leucistic king cobras are very rare.
  • They face many problems in the wild and often do not survive to adulthood.
  • Due to the white color of skin, they can not camouflage to hunt prey and to avoid predators.

What Do King Cobras Eat – King Cobras Diet

  • King cobras are carnivores and eat other snake species and lizards as their primary diet.
  • The major snake species they eat include; Indian cobra, pythons, banded kraits, banded wolf snake, rat snake, green whip snake, Blyth’s reticulated snake, and keelback.
  • They also prey on hump-nosed pit viper and Malabar pit viper by following their scent trails.
  • In case of food scarcity, they also eat small vertebrates, such as lizards and birds.
  • In Singapore, a king cobra was observed eating a clouded monitor.
  • King cobras do not chew food and swallow it as a whole (sometimes snakes larger than their head). They rely on the strong acids of their stomach to digest food.
  • King cobras sometimes constrict their prey by putting pressure on their muscular body. However, this is not common.
  • King cobras have a slow metabolic rate. After a big meal, they can survive for many months without food.

King Cobra Zoo Diet

  • In captivity, the diet of king cobras mainly consists of rodents.
  • At the Smithsonian National Zoo, king cobras are fed with mice and rats.

Cobras Hypnotize Their Prey

  • In the wild, cobras are observed fixating on prey with unblinking eyes.
  • When hunting, a king cobra sometimes raises one-third of its 18 feet long body off the ground and looks standing as tall as an adult human.
  • The prey animals are observed waiting for stationary rather than escaping as the snake approaches to engulf them.
  • While birds are observed fluttering in front of the snake rather than flying away to escape.
  • Witnesses say that king cobras look like hypnotizing their prey to submission.
  • However, scientists say that is not actually what’s happening and provide some theories to explain why some prey animals do not escape after confronting cobras;
    • The prey animals may be frozen due to extreme fear.
    • The prey animals may stare out of curiosity without realizing the danger they face.
    • According to Herps of North Carolina, the fluttering bird in the front of the snake is likely a mother who sacrificed herself in an attempt to divert the snake’s concentration from her nest of babies. 

King Cobra Food Chain

The following is the food chain of king cobra:

  • Sun is the all-inclusive energy source.


  • In the food chain of the king cobra, Indian weeds, Indian berries, and many other types of grasses are the producers. They take energy from the sun and prepare their food itself through the process of photosynthesis.

Primary consumers 

  • The primary consumers are the Indian bush rat, the lion-tailed Macaque, the Indian frog, and the China kata.

Secondary consumers 

  • The secondary consumers are the Bengal monitor, rat snake, and Indian scorpion.

Tertiary consumers 

  • Tertiary consumers in this food chain are the King Cobra and the Indian grey mongoose.

King Cobra Ecology

  • King cobras are mainly found in the rain forests and plains in India, Southern China, and Southeast Asia.
  • They play a vital role in their ecosystem by controlling the population of many animal species.
  • If the king cobra became extinct, the population of rat snakes and Bengal monitor would quickly extend in number. Their struggle for food would otherwise cause the near extinction of the primary consumers. 
  • After the near-extinction of primary consumers, the population of rat snakes and Bengal monitor would then fall due to food scarcity.
  • In the absence of king cobras, the Indian grey mongoose would also have not enough food to eat.
  • So king cobra is a critical part of its ecosystem.
