Ophiophagus hannah, also known as the king cobra, is a venomous snake found in the forests of Southeast Asia. It is the world's longest venomous snake, growing up to 18 feet long. As a symbol of strength and power, this majestic reptile has been featured in many myths, legends, and cultural traditions. Some synonyms for the king cobra include hamadryad, hamadryas viper, and naja hannah. Despite its deadly reputation, the king cobra plays an important role in the ecosystem by keeping the population of rats and other pests under control. However, the species faces threats due to habitat destruction and illegal wildlife trade.
