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.
