5. Blue Malayan Coral Snake
This is a medium-sized coral snake with a slender body. The adult can reach 1.8 meters (5 ft 11 in) long. It has a red head, tail, and belly. The back is dark blue to black in color, and it usually has a large blue or white stripe on each flank. They can be hard to find as they are quite reclusive and semi-fossorial. These snakes spend most of their time burrowing in the dirt and leaving in their heavily forested, mountainous habitats.
