It is readily recognised as it is an agile snake with a very slender body and tail. The dorsal body colour varies from green to olive-green to black, sometimes even blue. It is frequently pale yellow on the throat and belly but other pale colours have been noted. Blue flecks are present on the flanks. The eyes are larger than in most snakes. It is found in a variety of habitats ranging from rainforest to woodland to urban areas where it preys on fish, frogs, and other small animals.
