What is the world's largest species of venomous snake?

The world's largest venomous snake is the King Cobra (Ophiophagus hannah), also known as the hamadryad. They are found primarily in forests from India through Southeast Asia to Indonesia and the Philippines. King Cobras can reach lengths of up to 18 feet (5.5 meters), although the average size is around 10-13 feet (3-4 meters). They are distinctive in appearance, with their large size, hooded neck, and typically olive-green color with narrow black and yellow crossbands.

Despite their fearsome reputation, King Cobras are not particularly aggressive towards humans and will typically avoid contact if possible. They are shy and elusive creatures, and will generally only attack humans if they feel threatened or cornered. However, their venom is extremely potent and can cause respiratory failure or death in humans if left untreated.
