Description
With a triangular pattern and an array of colours such as green, red, orange, white, and black, this snake is quite impressive to look at. Unfortunately, they are not as common as the Javan Keelback, and are rarely sighted in the Jabodetabek area. These snakes are found near water, feed mainly on fish and frogs and are rear-fanged. Although venomous, these snakes are only dangerous to their prey and harmless to humans.
