what are the snake senses

The senses of snakes are very precious to them. Most species don’t see well and they don’t have limbs. They use their long tongue that allows  lets them pick up on various smells. Snakes can also tell which direction scents that they pick up are coming from. This can help them to go after their preys .

While snakes don’t have external ears they are still able to hear. They rely heavily on various types of vibrations that come all around them. They hear all the movements around them and this thing helps them to decide what to do.
There are species of snakes that have infrared vision too. This allows them to see the body heat of things around them. They can detect their location and their size.
They use their senses to help them determine when the temperatures are changing enough that they need to find a place for hibernating. They won’t do that the first chilly day that comes along. Instead, they will instinctively know by their senses when they need to slow down their metabolism for them to be able to survive until the warmer weather comes again.
Digestion can take a very long time for any snake, especially when they consume large meals. If they have a fear they will cause their bodies to expel the food. Then they can move again and get out of the way. This is a type of sense that prevents them from being unable to move as some form of predator or danger comes closer.

Garter snake



  • Where do they live?

The distribution for this snake is wide scale and it is the biggest of all reptiles found around North  America. This is the only known species of snake to naturally live in Alaska and some species became endangered in the wild.

  • How do they live?
They are able to find other snakes in their species by tracking the smells that they leave behind. They are able to distinguish between male and female scent too,and that is so special about them.
They will go into water but typically only as a way to escape from predators. They may find sources of food around this area too so they will hang out and see what they can find for dinner.

  • What do they eat?

Worms, tadpoles, rodents, and other similar living things are the diet of the Garter Snake. They will bite it and then swallow it whole. Since they don’t have very strong venom they aren’t able to immobile larger sized prey.

  • Is the garter snake dangerous?

It is very rare that a Garter Snake will bite but they are going to if they are surprised by a human. The bite should be washed and a doctor should look at it. Some people will have an allergic reaction but that is very unlikely to occur. Getting medical care though should be done as a safety precaution.

green tree python




The Green Tree Python lives in areas where most people will never get a chance to see one up close.The color of the Green Tree Python is a lime green. They may have a yellow color too depending on where you find them. For that reason though they are often mistaken for other species of snakes. Sometimes they even have blue tint. They can be up to 6 ½ feet long when they are fully mature.

  • Countries they live in:
New Guinea, Indonesia, and the Cape York Peninsula in Australia are the main locations for this species of snake. Since they blend in so well it is hard to know how many of them are really available.
They live in trees, forest regions, and tall grasses. In some locations their habitat continues to be taken away. Efforts by humans including logging continue to clear out areas where they live.

  • What do they do?

The Green Tree Python spends most of its live living in the trees. They will loop a coil around the trees and place their head in the middle.
They are well known to bite when someone or something provokes them. The males become more aggressive when they are looking for mates. The females become more aggressive when they have eggs to protect.

  • What do they eat?

Rodents, reptiles, and other small living things make up the majority of the diet for the Green Tree Python. They bite their prey and they will constrict around it. This is going to suffocate the prey so that it won’t be able to move or to breathe. Then will open up the jaws and swallow the prey. It can take days or weeks for the food they eat to fully digest.

  • Is the green python dangerous?

it's not too venomous.But, it is still important to be able to get medical attention after such a bite to prevent an infection. Researches suggests they aren’t strong enough or large enough to crush a human but they have been known to try to do so.

blecher's sea snake




Sea Snake is the most venomous snake known in the world, a few milligrams is strong enough to kill 1000 people! Less than 1/4 of bites will contain venom, and they are relatively docile. Fisherman are usually the victims of these bites, as they encounter the species when they pull nets from the ocean. Found throughout waters off South East Asia and Northern Australia.

Inland taipan snake


The incredible Inland Taipan deserves a spot of its own. It has the most toxic venom of any land snake in the world. The maximum yield recorded for one bite is 110mg, enough to kill about 100 humans, or 250,000 mice! With an LD/50 of 0.03mg/kg, it is 10 times as venomous as the Mojave Rattlesnake, and 50 times more than the common Cobra. No fatalities have ever been recorded, though it could potentially kill an adult human within 45 minutes.

Blue krait snake




The Malayan or Blue Krait is, by far, the most deadly of this species. Found throughout South East Asia and Indonesia, 50% of bites from the deadly Blue Krait are fatal, even with the administration of antivenin. Kraits hunt and kill other snakes, even cannibalizing other Kraits. They are a nocturnal breed, and are more aggressive under the cover of darkness. However, overall they are quite timid and will often attempt to hide rather than fight. The venom is a neurotoxin, 16 times more potent than that of a Cobra. It quickly induces muscle paralysis by preventing the ability of nerve endings to properly release the chemical that sends the message to the next nerve. This is followed by a period of massive over excitation (cramps, tremors, spasms), which finally tails off to paralysis. Fortunately, bites from Kraits are rare due to their nocturnal nature. Before the development of antivenin, the fatality rate was a whopping 85%. Even if antivenin is administered in time, you are far from assured survival. Death usually occurs within 6-12 hours of a Krait bite. Even if patients make it to a hospital, permanent coma and even brain death from hypoxia may occur, given potentially long transport times to get medical care.

Black mamba

Blackmamba is the feared Black Mamba is found throughout many parts of the African continent. They are known to be highly aggressive, and strike with deadly precision. They are also the fastest land snake in the world, capable of reaching speeds of up to 20km/h. These fearsome snakes can strike up to 12 times in a row. A single bite is capable of killing anywhere from 10-25 adults. The venom is a fast acting neurotoxin. Its bite delivers about 100–120 mg of venom, on average; however, it can deliver up to 400 mg. If the venom reaches a vein, 0.25 mg/kg is sufficient to kill a human in 50% of cases. The initial symptom of the bite is local pain in the bite area, although not as severe as snakes with hemotoxins. The victim then experiences a tingling sensation in the mouth and extremities, double vision, tunnel vision, severe confusion, fever, excessive salivation (including foaming of the mouth and nose) and pronounced ataxia (lack of muscle control). If the victim does not receive medical attention, symptoms rapidly progress to severe abdominal pain, nausea and vomiting, pallor, shock, nephrotoxicity, cardio toxicity and paralysis. Eventually, the victim experiences convulsions, respiratory arrest, coma and then death. Without antivenin, the mortality rate is nearly 100%, among the highest of all venomous snakes. Depending on the nature of the bite, death can result at any time between 15 minutes and 3 hours.

Taipan snake


Coastal taipan entry from Australia, the venom in a Taipan is strong enough to kill up to 12,000 guinea pigs. The venom clots the victim’s blood, blocking arteries or veins. It is also highly neurotoxic. Before the advent of an antivenin, there are no known survivors of a Taipan bite, and death typically occurs within an hour. Even with successful administration of antivenin, most victims will have an extensive stay in intensive care. It has been likened to the African Black Mamba in morphology, ecology and behavior.

Viper snake


Saw-Scaled-Viper Vipers are found throughout most of the world, but arguably the most venomous is the Saw Scaled Viper and the Chain Viper, found primarily in the Middle East and Central Asia, particularly India, China and South East Asia. Vipers are quick tempered and generally nocturnal, often active after rains. They are also very fast. Most of these species have venom that cause symptoms that begin with pain at the site of the bite, immediately followed by swelling of the affected extremity. Bleeding is a common symptom, especially from the gums. There is a drop in blood pressure and the heart rate falls. Blistering occurs at the site of the bite, developing along the affected limb in severe cases. Necrosis is usually superficial and limited to the muscles near the bite, but may be severe in extreme cases. Vomiting and facial swelling occurs in about one-third of all cases. Severe pain may last for 2-4 weeks. Often, local swelling peaks within 48-72 hours, involving the affected limb. Discoloration may occur throughout the swollen area as red blood cells and plasma leak into muscle tissue. Death from septicaemia, respiratory or cardiac failure may occur 1 to 14 days post-bite, or even later.

Tiger snake


Tiger Snake are found in Australia, the Tiger snake has a very potent neurotoxic venom. Death from a bite can occur within 30 minutes, but usually takes 6-24 hours. Prior to the development of antivenin, the fatality rate from Tiger snakes was 60-70%. Symptoms can include localized pain in the foot and neck region, tingling, numbness and sweating, followed by a fairly rapid onset of breathing difficulties and paralysis. The Tiger snake will generally flee if encountered, but can become aggressive when cornered. It strikes with unerring accuracy.

Philippine cobra


The Philippine Cobra is awesome. Drop by drop, its venom is the most deadly of all the Cobra species, and they are capable of spitting it up to 3 metres. The venom is a neurotoxin which affects cardiac and respiratory function, and can cause neurotoxicity, respiratory paralysis and death in thirty minutes. The bite causes only minimal tissue damage. The neurotoxins interrupt the transmission of nerve signals by binding to the neuro-muscular junctions near the muscles. The symptoms might include headache, nausea, vomiting, abdominal pain, diarrhea, dizziness, collapse and convulsions.

Death adder snake



The appropriately named Death Adder is found in Australia and New Guinea. They actually hunt and kill other snakes, including some on this list, usually via ambush. Death Adders look quite similar to vipers, in that they have triangular shaped heads and short, squat bodies. They typically inject around 40-100mg of venom with an LD of 0.4mg-0.5mg/kg. An untreated Death Adder bite is one of the most dangerous in the world. The venom is a neurotoxin. A bite causes paralysis and can cause death within 6 hours, due to respiratory failure. Symptoms generally peak within 24-48 hours. Antivenin is very successful in treating a bite from a Death Adder, particularly due to the relatively slow progression of symptoms, the quickest strike in the world, a Death Adder can go from strike position to striking and back again within 0.13 of a second.

Rattle snake


The only snake from the Americas on the list, the Rattlesnake is easily identifiable by the tell tale rattle on the end of its tail. They are actually a part of the Pit Viper family, and are capable of striking at up to 2/3rd their body length. It's considered the most venomous species in North America. Surprisingly, juveniles are considered more dangerous than adults, due to their inability to control the amount of venom injected. Most species of rattlesnakes have hemotoxic venom, destroying tissue, degenerating organs and causing coagulopathy (disrupted blood clotting). Some degree of permanent scarring is very likely in the event of a venomous bite, even with prompt, effective treatment, and can lead to the loss of a limb or death. Difficulty breathing, paralysis, drooling and massive hemorrhaging are also common symptoms. Thus, a rattlesnake bite is always a potentially fatal injury. Untreated rattlesnake bites, especially from larger species, are very often fatal. However, antivenin, when applied in time, reduces the death possibility.

cobra snake

Identification: Cobra is the portuguese word for 'snake' and it has been adopted by the English language referring to any species of venomous snakes. Most of them can spread their neckribs to form a flattened surface as the picture below. she can live up to 20 years.
  • how much is the cobra dangerous?: cobras venom is not the strongest one up there, but cobras can inject so much venom that can kill an elephant with. Most cobras are shy and they run and hide when people are around. And sometimes their bite is not dangerous because it could be a "dry bite".
  • cobra specialties: they build a nest for their young as seen in the picture below,  and the cobra can lay between 20 to 40 eggs in one nest. Cobras are the only snakes that can spit there venom. They are not blind , they can even see at night.They can sense small temperature changes.



  • how to kill a cobra?:The only lethal measure recommended is a long-handled shovel or hoe to kill the snake by severing the head from the body. DO NOT handle the head of a venomous snake alive or dead. A recently killed snake may bite by reflex action.
