It’s a question that we’ll be exploring in this article.
When it comes to rattlesnakes, it’s easy to get caught up in their reputation as deadly predators. However, many people fail to realize that not all snakes are venomous. In fact, there are over 3,000 species of snakes in the world, but only around 20% of them are venomous. So, are rattlesnakes poisonous yes or no? Well, the answer lies in the fact that they are indeed venomous, but that doesn’t necessarily mean they are always dangerous to humans. Depending on a variety of factors, the level of toxicity in a rattlesnake’s venom can vary greatly, and not all bites will result in fatal consequences.
So, if you come across a rattlesnake on your next outdoor excursion, should you be worried? Well, it’s always better to err on the side of caution and keep your distance. But, with a little knowledge and awareness, you can learn to coexist with these fascinating creatures in a safe and respectful manner. In the following paragraphs, we’ll be diving deeper into the world of rattlesnakes and exploring some of the fascinating facts surrounding their venomous nature.
Types of Venomous Snakes
Out of over 3,000 species of snakes in the world, only about 600 are venomous. The venomous snakes are found all over the world except in Antarctica, Ireland, Iceland, and New Zealand. These snakes have venom glands that produce venom which they use to immobilize their prey. Venomous snakes are often categorized into four groups based on their types of venom:
- Cytotoxic venom: This type of venom affects the cells and tissues near the bite site and can cause severe pain, swelling, and tissue damage. Snakes like copperheads and rattlesnakes have cytotoxic venom.
- Neurotoxic venom: This type of venom affects the nervous system and can cause paralysis and respiratory failure. Snakes like cobras and mambas have neurotoxic venom.
- Hemotoxic venom: This type of venom affects the blood and can cause uncontrollable bleeding, organ failure, and shock. Snakes like vipers and pit vipers have hemotoxic venom.
- Myotoxic venom: This type of venom affects the muscles and can cause muscle tissue damage and renal failure. Snakes like the Mojave rattlesnake and lanceheads have myotoxic venom.
Subspecies of Venomous Snakes
Venomous snakes can be found in almost all parts of the world. Here are some of the most common subspecies of venomous snakes and where they are found:
- Rattlesnakes: Found in North and South America, these snakes have a rattle on their tail and are known for their loud warning sound.
- Cobras: Found in Asia and Africa, these snakes are recognized by their iconic “hood” and are known to spit venom.
- Vipers: Found in Europe, Asia, and Africa, these snakes have large fangs and are known for their deadly bite.
- Taipans: Found in Australia and Papua New Guinea, these snakes are one of the most venomous in the world and can deliver a lethal bite within minutes.
Table of Venomous Snakes and Their Types of Venom
| Snake Species | Type of Venom |
|---|---|
| Rattlesnakes | Cytotoxic |
| Cobras | Neurotoxic |
| Vipers | Hemotoxic |
| Taipans | Neurotoxic |
It’s important to note that not all venomous snakes are lethal to humans. However, it’s still crucial to take caution around snakes and seek medical attention if bitten by a venomous one.
Nonvenomous Snakes Often Mistaken for Rattlesnakes
While rattlesnakes are undoubtedly venomous, many people mistakenly identify nonvenomous snakes as rattlesnakes due to their similar appearance. Here are some examples of nonvenomous snakes that are often mistaken for rattlesnakes:
- Bullsnake – also known as the gopher snake, this snake can be found in many of the same areas as rattlesnakes. They can grow up to 8 feet in length and have a distinctive pattern on their back that can resemble a rattlesnake.
- Hognose Snake – this snake has an upturned snout and can flatten its head to resemble a venomous snake. However, hognose snakes are actually harmless and rarely bite humans.
- Milk Snake – with their vibrant colors and pattern, milk snakes are often mistaken for rattlesnakes. However, they are completely harmless and are actually known for their ability to prey on other snakes.
Identifying Rattlesnakes from Nonvenomous Snakes
If you come across a snake in the wild, it’s important to be able to identify whether it’s a venomous rattlesnake or a harmless nonvenomous snake. Here are some key ways to differentiate between the two:
- Rattlesnakes have a triangular-shaped head, whereas nonvenomous snakes have a more rounded head.
- Rattlesnakes have a rattle on the end of their tail, which makes a distinct rattling noise when they feel threatened. Nonvenomous snakes do not have a rattle.
- Most rattlesnakes have vertically slit pupils, like a cat, whereas nonvenomous snakes have round pupils.
Rattlesnake Venom Types
It’s important to note that not all rattlesnake venom is the same. In fact, there are several different types of rattlesnake venom, each with its own specific properties and effects. Here is a breakdown of the main types of rattlesnake venom:
| Venom Type | Effects |
|---|---|
| Hemotoxic | Destroys tissue and causes internal bleeding |
| Neurotoxic | Affects the nervous system and can cause paralysis or respiratory failure |
| Cytotoxic | Destroys cells and tissues at the site of the bite |
Overall, it’s important to be vigilant and cautious when encountering snakes in the wild. While many nonvenomous snakes can be harmless, it’s always better to err on the side of caution and assume that a snake is venomous until proven otherwise.
Rattlesnake Bite Symptoms
Being bitten by a rattlesnake can cause a range of symptoms that can vary depending on the species of snake, the amount of venom injected, and the location of the bite.
The following are some common symptoms associated with a rattlesnake bite:
- Severe pain and tenderness at the bite site
- Swelling and redness around the bite
- Difficulty breathing
- Nausea and vomiting
- Weakness and dizziness
- Numbness or tingling in the face, arms, or legs
- Blurred vision or other vision problems
- Loss of muscle coordination
- Convulsions or seizures
If you are bitten by a rattlesnake, it is important to seek medical attention immediately. Time is of the essence when dealing with snakebites, as the venom can cause serious medical complications and even death if left untreated.
The severity of the symptoms can also depend on the age and health of the person bitten. Children and elderly individuals may experience more severe symptoms due to weaker immune systems and other health complications.
| Severity of Bite | Symptoms |
|---|---|
| Mild | Localized pain and swelling at the site of the bite |
| Moderate | Pain and swelling that spreads beyond the bite location |
| Severe | Widespread pain and swelling, respiratory distress, muscle weakness, and other systemic symptoms |
It is important to note that not all snakebites result in the injection of venom. A dry (or venom-free) bite can still cause pain and swelling, but it will not result in the same medical complications as a venomous bite.
Treatment for Rattlesnake Bites
Rattlesnakes are venomous snakes that can cause serious harm to humans and animals. It is important to seek medical attention immediately if bitten by a rattlesnake, even if the bite appears to be minor.
There are a few things you can do while waiting for medical assistance:
- Stay calm and still to slow the spread of venom through your body
- Keep the bitten area at or below heart level to reduce blood flow to the area
- Remove any tight clothing or jewelry near the bite to help with swelling
Once you arrive at the hospital or medical facility, the medical team will evaluate the severity of the bite and administer the appropriate treatment. Depending on the severity of the bite, treatment may include:
- Antivenom: A type of medication that neutralizes the venom in the body
- Pain medication: To alleviate pain and discomfort from the bite
- Tetanus shot: If the bite is deep and punctures the skin, a tetanus shot may be necessary to prevent infection
Antivenom Therapy for Rattlesnake Bites
Antivenom therapy is the primary and most effective treatment for rattlesnake bites. Antivenom is a medication that is created from venom made by a specific snake species. It works by neutralizing the venom in the body and stopping it from further damaging tissues and organs.
The antivenom therapy process involves:
- Administration of a small test dose of antivenom to check for an allergic reaction
- If no allergic reaction occurs, a larger dose of antivenom is administered
- Monitoring the patient for several hours to ensure the antivenom has been successful in negating the venom
| Antivenom Type | Approved for Use in USA |
|---|---|
| CroFab | Yes |
| Anavip | Yes |
| Crotalidae Polyvalent Immune Fab | Yes |
| Wyeth Antivenin | No longer available |
It is important to note that antivenom therapy may not be recommended for those with mild or non-life threatening symptoms. However, it is still important to seek medical attention as other treatments, such as pain medication or wound care, may be necessary.
