“Daboia russelii” is an Indian cobra that can be found in India, Sri Lanka, Myanmar, Nepal, Andaman islands and Vietnam. The venom of this snake causes haemorrhaging and fluid accumulation around the lungs which eventually leads to suffocation.

It has a heavy body with dark brown irregular markings on its back that extend down its tail (except for one spot). This species does not have any big teeth or long fangs like other venomous snakes.

The “Daboia russeli”, unlike others, includes venoms causing post-synaptic neurotoxic effects which affect the nerve cells. This snake mainly preys on lizards, frogs, and other small animals like rats but there have been cases where humans have also fallen prey to this viper.

This large snake is not dangerous in general unless provoked or threatened.

The bite from a Daboia russeli is very painful and there appear symptoms like paralysis, convulsions, and bleeding at the site of the wound within thirty minutes after being bitten by one. The presence of fang marks identifies that it is an Indian cobra’s venom causing this reaction.

How to avoid being bitten by a snake, spiders, or other animals

When you are traveling to Vietnam, there is a lot of wildlife that you can see. This country has more than 500 different species of mammals and 300 types of reptiles! In this article, I am going to give some tips on how not only to enjoy your trip but also avoid any accidents with the animals in the area by following these simple rules.

  • Make sure to wear clothes that cover your skin and long sleeves because sometimes you can get bitten by a spider without seeing it.
  • If you are walking in the mountains, do not walk barefoot because there could be many poisonous animals or snakes that could attack your feet. If you have to cross between tall grasses, make sure that you use some kind of footwear on your feet, like shoes or sandals. You will prevent many potential accidents that way!
  • Get information about the area where you will go and look for trails suitable for your level of experience (in case of adventure trips). The forest is full of different kinds of plants so if they are too close together, it’s easy to get lost! In case of emergency or if you hear any noise coming from the woods, leave immediately and find a safe place to hide. Do not move while you are in the woods because it makes you very vulnerable and easier for animals to spot you!
  • Make sure to check your shoes before putting them back on. This is the most common way for many people to get bitten by a poisonous snake on their trip to Vietnam.
  • If you are camping in the jungle, try not to use any bright colors.
  • As you can see, there are many things that you can do to avoid getting hurt by snakes and other animals while traveling in this amazing country. Stay smart and safe!
  • It’s best not to walk barefoot or go for hikes in the wild.
  • Stay away from trees, bushes, tall grasses, logs, and other places where there might be hiding places for animals.
  • If you were bitten by some kind of animal, do not try to pull out the tooth or sting that remains in your skin. Instead, cover it with a clean cloth and apply pressure on it so that blood does not flow out too fast. Try to find medical help as soon as possible (following any local advice) but never drink alcohol before getting treatment because it increases the risks of infection! Always remember: no matter how many precautions you take there is always a chance you will encounter some wild animal somewhere on your journey. So if this happens make sure that you know exactly what to do to avoid any danger. Good luck with your trip!

The best ways to protect yourself from wild animals and insects in Vietnam

The best ways to protect yourself from wild animals and insects in Vietnam can be summarized as follows:

1. Bring a small flashlight when you go on walks or hikes in the evening. Flashlights will scare away animals that might come after and cause you problems.

– 2. Do not wear fragrances, perfumes, hairspray, or other scented items while walking through crowded areas like parks and subways because these will attract bugs unnecessarily

– 3. Always carry insect repellent with at least 20 percent DEET for exposed skin as well as clothing while outdoors during peak hours of mosquito activity

– 4. If bitten by any animal stay still (no sudden movements) without provoking it and try not to scream because sudden movements can trigger an instinct in the animal to go for your throat. Instead, keep calm and avoid eye contact then slowly back away while maintaining a non-threatening posture

– 5. In case of emergency or life-threatening situation always seek professional medical attention as soon as possible and try not to panic

6. The best way to prevent attacks from animals is by following all the safety tips above (and many more) but also by avoiding areas where wild animals roam freely like national parks and nature reserves unless you have sought permission from park rangers first

What to do if you're attacked by an animal

When you’re faced with a wild animal, your body’s natural response is fight or flight.

In many situations, there won’t be time to do both. It’s up to you at the moment to decide which will propel you into safety and keep you from injury. When defending yourself against an animal attack try not to panic and make as much noise as possible, Noisemakers can help scare the attacker away if you are not armed with anything else but they should also act as a signal for potential first-responders if needed.

If you have something around that could function as a weapon like pepper spray or an empty water bottle, then use it only if necessary since animals may either attack out of fear (eagles) or to protect their young (males), or to defend territory (jaguars)
