Green snakes are among the most fascinating reptiles on Earth, not only because of their bright colouration but also due to their role in the ecosystem. Green snakes inhabit all of North America, Africa, Asia, and South America and are greatly diverse concerning behaviour, habitat, and biology. Some are harmless insect-eaters, but others are dangerously venomous and predatory. Regardless of their variations, green snakes all have one outstanding feature—outstanding camouflage capabilities that enable them to merge into vegetation and treetops seamlessly.

Green serpents around the world
Green snakes are possibly the most vibrant, most stunning reptiles on our planet. Not only is their vibrant green hue very camouflaged in vegetation habitats, but it also hints at the very advanced adaptations to environments that shift—either North American prairies, dense Asian-African rainforests. While some of them are innocuous, others of them are the deadliest snakes on our planet. Below is a closer look at some of the world's most sought-after green snake species:
Smooth green snake (Opheodrys vernalis)
A harmless, North American serpent with smooth, glossy scales and a long, slender body. They live in meadows, woodland edges, and marshes, where they remain hidden from predators due to their bright green color. Day-active, and almost entirely an insectivorous diet of caterpillars, grasshoppers, and spiders. By their innocuous nature and beneficial function as biological control agents of pest organisms, they are much valued for their contribution to local ecosystem well-being. Habitat loss and pesticide poisoning cause local declines.
Rough green snake (Opheodrys aestivus)
Similar in size and diet to the smooth green snake, the rough green snake is different in texture—it possesses keeled scales, providing a slightly coarser texture on the snake. Residing mostly in the southeastern United States, this snake is most arboreal and spends a considerable amount of time roaming around shrubs, vines, and trees in vicinity to lakes and rivers. Their green color allows them to blend in while feeding on spiders and insects. No threat to humankind, these snakes are useful population regulators of those insects that inhabit forests and swamps.
Asian vine snake (Ahaetulla prasina)
Native to wooded regions of Southeast Asia, the Asian vine snake is very, very long and thin and very greenish—in appearance that makes it almost invisible amidst the vines on which it appears to sprout. It is extremely badly venomous, using its venom to paralyze small prey such as frogs, lizards, and birds. While its venom is not dangerous to human beings, the snake has a long, narrow head and bulging eyes, so it is extremely frightening to see. Its camouflage and stealth features make it a master ambush predator of forest canopy cover.
Boomslang (Dispholidus typus)
Boomslang is Africa's most dangerous rear-fanged snake. Adults pale green with dark stripes, females paler. Tree-dwelling, solitary snake that feeds on birds, eggs, chameleons, and rodents. Internal haemorrhages are lethal if left untreated, though bites are exceptional due to the snake's reclusive, shy nature. Though venomous and deadly, it is a vital player in keeping stocks of prey at low density in forest ecosystems.
Emerald tree boa (Corallus caninus)
A native of the Amazon, this good-looking nonpoisonous boa is highly valued for its glowing emerald green color and white zigzag pattern. A arboreal animal by nature, it coils around a branch and rigidifies in position as it prepares to strike at its prey, including birds, bats, and rodents. It kills by squeezing. In contrast to most snakes, the emerald tree boa gives birth to live young rather than laying eggs—a characteristic fully in line with its arboreal existence.
Eastern green mamba (Dendroaspis angusticeps)
Found in East and Southern African woodland and coastal thicket, one of Africa's most venomous snakes, the eastern green mamba.
It is highly green, slender, and highly agile. Though it possesses fatal neurotoxic venom, otherwise, it is timid and harmless. It is a bird-, rodent-, and reptile-eater. Its encounter with human beings is low because of the loss of habitats and due to its timidity, but it is useful in controlling the rodents.
Western green mamba (Dendroaspis viridis)
They are similar to the eastern green mamba but are found in forest and woodland savannas in West Africa. Same is its tree-dwelling habit, very deadly venom, and way of feeding. Similar to its cousin, western green mamba possesses agility to the body with corresponding fast velocities and uses such speed in pursuit of lizard and bird prey via ambush attack. As strong as it looks but as dangerous too, the animal is only currently aggressive when feeling threatened.
Green tree python (Morelia viridis)
One of the most vibrant snakes, the green tree python can be found in New Guinea, Indonesia, and Australia's Cape York Peninsula. It is non-poisonous and will spend most of its life curled on trees. It's a nocturnal bird, frog, and small mammal predator. The female green tree python is an egg-laying species that will guard the eggs prior to hatching, a behavior that provides additional protection in the wild. The young are red or yellow colored and turn green adults—a characteristic not shared by snakes.
Parrot snake (Leptophis ahaetulla)
This thin and elongated, swift serpent comes from the thick Central and South American tropical rain forests. This snake has very big eyes and a prehensile tail, which is long and beneficial in dense shrubs. Parrot snakes are egg-laying into hidden locations, being oviparous. They eat frogs, lizards, and small birds but are very venomous. Although slightly toxic, they are not harmful to man. Their stunning green color makes them difficult to locate in the wild.
