We enjoy the view of colorful things like rainbow and flowers, but things should go differently with colorful snakes. Brightly colored snakes are indeed beautiful; however, the colors are also the signs telling us that they are dangerous. The part that we can’t deny is that some of these colorful snakes are so gorgeous to look at. Yet once you get near them, the beauty you adore can turn into your worst nightmare with just one strike. In case you want to know which colorful snakes are venomous, take a look at the list below.

1Banded Krait

Habitat: Indian Subcontinent, Southeast Asia

With a maximum length of up to 2.1 meters, this krait is one of the largest and most dangerous kraits. You can easily identify them by their black and yellow crossbands as well as the triangular body cross section. These kraits is common across Southeast Asia in a variety of habitats ranging from forests to agricultural lands. Most of the time, banded kraits are shy and slow during the day, and they are not interested in striking at all. Bites usually occur at night, and these snakes tend to be more aggressive and dangerous when the sun goes down. When bitten, the victims are likelly to experience effects such as vomiting, abdominal pain, diarrhoea, and dizziness. In severe cases, the envenomation can lead to respiratory failure while death may occur due to suffocation. A polyvalent antivenom to this snake is only available in India at the moment.

2Blue Malaysian Coral Snake

Habitat: Southeast Asia

This species is a venomous elapid as well as one of the most beautiful and coloful snakes. The snake has red coloration on its head, tail, and belly while the back is dark blue or black. Usually, they also have a large blue or white stripe on each flank as well. This species prefer to live in under and forage under as well as on top of leaves and fallen trees and rocks. Normally, they always avoid people and other large threats, and they can be very fast as they flip about almost spastically.

There have been many people free-handled these snakes without realizing how lethal their venom can be. The unique thing about their venom is that it does not contain neurotoxin like other snakes at all. Their venom consists of cytotoxin that leads to the destruction of muscle tissue or promotes the release of adenosine. That can cause hypotension, inflammation, and neurotransmitter blockade in victims after the bite. The victim may die as fast as within 5 minutes of envenomation, so make sure to not touch such deadly snake.

3Boomslang

Habitat: Africa

Boomslang is a perfect example for the phrase that says “never trust a pretty face”. This is a large snake species that is swift, agile, and of course, venomous. The good part about them is that they are shy and non-aggressive so they don’t attack humans out of the blue at all. Their name means “tree snake” in Dutch and Afrikaans, and that is where they live. Boomslangs spend most of their time chilling out in trees in a variety of environments mainly from coastal thickness to savannahs.

Just like most venomous colorful snakes, this one also display their bright colors as well. The coloration of a boomslang ranges from green and yellow to pinkish reds, and they look super cute. Plus with their stunning large eyes, boomslangs are one of the most beautiful snakes in the world. However, such beauty can mess you up with just one bite. The venom of a boomslang contains hemotoxic which destroys red blood cells, disrupts the clotting process, and causes tissue and organ degeneration.

The first stage of the bite could be a headache, nausea, and sleepiness before things move on to the next stage. Then the victim will experience hemorrhage ensues which cause them to bleed from their gums. Sometimes, the body of the victims will also turn blue because of the widespread internal bleeding. The process can be slow and take take as long as five days until the victims die of internal bleeding. The good thing is that antivenom is available, and boomslangs don’t usually attack humans first at all.

4Eyelash Viper

Habitat: Central America, South America

I don’t know about you, but I would totally adopt this viper if it was not so venomous and deadly. The name already suggests the main beauty of this serpent, their beautiful unique set of scales that resembles eyelashes. But don’t let this stunning appearance trick you because eyelash vipers are also famous for their aggression and lightning fast strikes. Their colors range from red, yellow, brown, green, and pink to various combinations of many other colors. Such bright colors help them to camouflage in bushes, berries, and fruits easily. Their habitats are tropical rainforest, wooded cloud and montane forest, dense sea-level forests, and streamside vegetation in lowlands and foothills.

They often spend most of their lives in trees, palms, shrubs, and vines, and they prefer to stay near a permanent water source. The eyelash viper is an ambush predator, and they wander alone as they hunt at night. These snakes can wait for hours before they unleash a lightning fast attack and inject lethal hemotoxic venom. The venom affects both the cardiovascular system and the central nervous system which is highly toxic and fatal. Eyelash vipers inject the venom using their 2 extremely long fangs on the upper jaw. The bite can cause severe pain, swelling, bruising, bleb formation, and very often necrosis. If the victims don’t treat the wound on time, it can lead to loss of a limb or even worse, death.

Wagler’s vipers come in a wide variety of bright beautiful colors and patterns which are known as phases. These snakes inhabit in various places in Southeast Asia mainly in lowland forests as well as some coastal regions. If you ask how dangerous are they, the rate would be 7 out of 10 mainly because of their speed.

These vipers can strike very quickly both on their prey and predators, but they are not aggressive at all. You can easily notice them by their scary and markedly triangular head as well as their bright color. In case you want to see them in real life, you may take a trip to the Snake Temple in Penang, Malaysia. The temple is a plethora of free-roaming snakes, most of which are Wagler’s Vipers.
