Vine snakes appear in two colors; gray or brown species that inhabit the savannas or dry forests, and green species found primarily in rainforests. They have narrow heads and slender bodies with pointed snouts. Let’s discover the largest vine snake ever found!
What’s the Largest Vine Snake Ever Found?
Oxybelis fulgidus is the largest vine snake. Also known as the flatbread snake or green vine snake, Oxybelis fulgidus is a slender, elongated arboreal colubrid snake. It’s commonly called cobra bicuda, cipo, bejuquilla verde, and bejuca lora in South America. This snake is often mistaken for the green-colored species in the genus Ahaetulla, which are also called “green vine snakes.” Oxybelis fulgidus is roughly 0.79 inches thick and can grow up to a total length of 59 to 79 inches (5 to 7 feet), whereas Ahaetulla species can grow to be 2.5 to 5 feet long. Its tail is very long and appears delicate. Like other vine snakes, Oxybelis fulgidus’ head is pointy and has a large mouth that extends almost the whole length of the head. It keeps its long and green tongue outside the mouth. It’s believed that Oxybelis fulgidus uses its tongue to navigate through branches and brush. Oxybelis fulgidus has a distinctive snout about three times as long as the eye diameter. It is yellowish-green ventrally on the upper lip and bright green dorsally, with a prominent yellowish-white stripe along both sides of the belly and tail. It has weekly keeled dorsal scales arranged in 17 rows at the midbody.
Where can you find Oxybelis fulgidus?
Oxybelis fulgidus is endemic to Central America and northern South America. It’s diurnal and spends most of its life high on trees. They prefer wooded and bushy areas, including gardens, parks, and plantations. Oxybelis fulgidus is widely distributed in its habitats and is not on the list of endangered animals.
Is Oxybelis fulgidus dangerous to humans?
Oxybelis fulgidus is mildly venomous. Its bite has little or no effect on humans but is fast-acting on small animals. Its bite only induces numbness or tingling sensations. However, it may trigger severe allergic reactions, so caution should still be taken while handling this snake.
What Do Oxybelis fulgidus Eat?
Oxybelis fulgidus are carnivores. Their diet primarily consists of frogs, small birds, lizards, and mice, among other animals. They are solitary reptiles that hunt their prey in a “sit and wait” manner, hiding in thick branches. When it locates the prey, Oxybelis fulgidus follows it while smelling to ensure it’s the ideal prey. If Oxybelis fulgidus is content with the prey, it bites into the head and lifts it 8-15.5 inches off the ground. It does so to prevent the prey from using its physical strength. Oxybelis fulgidus has two more prominent upper teeth at the back of its mouth, which transfer the toxic saliva into the prey to immobilize it. This vine snake then swallows the prey and finds somewhere to rest, usually at the highest point of a tree.
Can you keep an Oxybelis fulgidus as a Pet?
Although interesting, Oxybelis fulgidus can be challenging to keep as a pet due to health needs. They are also exceptionally delicate to handle. However, they can make wonderful display animals. These snakes must be kept in high terrariums with a height of about 79 inches and a 65-172 square feet surface. Their behavior towards humans is neutral, but handlers are advised to wear a thick pair of gloves when attending to these vine snakes. Oxybelis fulgidus readily takes mice or rats, unlike their Asian look-alikes, who are hard to tame. Most of them adapt well and may even come closer to you, which is why they are often highly-priced by reptile collectors. With good care, Oxybelis fulgidus may have an average life expectancy of up to 20 years.
What Are the Other Types of Vine Snakes?
Here are three other types of vine snakes:
1. Ahaetulla
Commonly referred to as the Asian whip snake or Asian vine snake, Ahaetulla is an elegant and slender colubrid distributed throughout tropical Asia. The genus Ahaetulla is derived from the Sinhalese name ehetulla for Ahaetulla nasuta, which means “eye striker” or “eye plucker.” Like other vine snakes, Ahaetulla does not possess a sophisticated venom delivery system. Their large teeth are located in the back of the jaw, unlike those of cobras and vipers. All Ahaetulla species are characterized by thin bodies of about 2.5 to 5 feet long. They have a sharply triangular-shaped head and extremely long tails. Their primary color is green, though they can vary quite a bit to browns, greys, oranges, and yellows. There are approximately 18 species of vine snakes in the genus Ahaetulla.
2. Imantodes
Also known as blunt-headed tree snakes, Imantodes are neotropical vine snakes found in Central America and throughout the coastal countries of western and northern South America. These snakes have long, slim bodies, thin necks, and large heads. They inhabit primary and secondary growth forests but can also be found in plantation areas. These species are pale brown dorsally and white ventrally with dark-brown blotches. Their body length can exceed 3 feet. Their snout-to-vent length accounts for 2 feet of their total body length. Like the other vine snakes, Imantodes also have rear fangs.
3. Thelotornis
Thelotornis are also known as twig snakes, vine snakes, or bird snakes. They are rear-fanged venomous snakes native to Africa. All species of the genus Thelotornis have slender and elongated bodies of about 48 inches, narrow heads, long tails, and pointed snouts. They are grayish-brown with faint light and dark markings. Of all the vine snakes, twig snakes are the most deadly. So far, twig snakes have caused human deaths, including that of Robert Mertens, a famous herpetologist who was bitten by his beloved pet savanna vine snake (Thelotornis capensis). Their venom is hemotoxic, which affects the blood clotting mechanism, causing uncontrolled internal hemorrhaging and bleeding. However, they hardly bite unless mishandled.
