The king cobra (Ophiophagus hannah) is the world’s longest venomous snake and is native to forests across Southeast Asia and parts of the Indian subcontinent. Here’s a description of its distribution by country:

1. India: King cobras are found in various regions of India, particularly in the western and southern parts of the country. They inhabit forests, grasslands, and agricultural areas across states such as Kerala, Karnataka, Tamil Nadu, Andhra Pradesh, and Maharashtra.
2. Bangladesh: King cobras are native to Bangladesh, where they inhabit forested areas, including the Sundarbans mangrove forest and other regions of the country.
3. Myanmar (Burma): King cobras are found in Myanmar, particularly in forested regions across the country, including the Irrawaddy Delta and the forests of the Shan Hills.
4. Thailand: King cobras are native to Thailand, where they are found in various habitats, including tropical forests, grasslands, and agricultural areas.
5. Indonesia: King cobras are found in Indonesia, particularly on the islands of Sumatra and Java, where they inhabit forests and agricultural landscapes.
6. Malaysia: King cobras are native to Malaysia, where they are found in forests and agricultural areas across the peninsula and the island of Borneo.
7. Vietnam, Laos, Cambodia, Singapore, Brunei: King cobras are also found in these countries, where they inhabit forested areas and sometimes venture into urban environments.

King cobras are apex predators, feeding primarily on other snakes, including venomous species. Despite their fearsome reputation, they are shy and elusive animals that prefer to avoid confrontation with humans. However, they are threatened by habitat loss, habitat fragmentation, and persecution by humans due to misconceptions and fear. Conservation efforts aim to protect their habitats and raise awareness about their importance in maintaining ecological balance.
