What’s the Difference Between Venomous and Poisonous?

Difference Between Venomous and Poisonous

What’s the difference between venomous and poisonous? Most people know that venomous has something to do with venom or poison, but they may not know precisely what that means or how it differs from poisonous.

When you see the word venomous, your mind immediately associates it with something dangerous and poisonous. 

However, it turns out that there are several species of venomous animals that aren’t poisonous, and there are quite a few poisonous animals that aren’t venomous at all!

Read on to find out the difference between venomous and poisonous, so you can know if your subsequent encounter with an animal will end up in death or just a painful sting!

What is Poison?

Poison is a natural or artificial substance that can cause harm or death if ingested, inhaled, or absorbed through the skin. All poisons are poisonous, but not all poisonous substances are toxic.

The difference between venomous and poisonous is that venom must be injected into the body to cause harm, while poison can enter the body in various ways. 

Poison is a substance that causes harm or death to an organism when ingested, inhaled, or absorbed.

The difference between venomous and poisonous is that venom is injected while poison is not. Also, venom is produced by an animal, while both animals and plants can make poison. 

Types of poisonous animals

There are three types of poisonous animals- those that have poison glands, those that accumulate poisons, and those with venom.

Animals with poison glands have a sack of poison that they secrete when they feel threatened. Animals that get poisons take in environmental toxins and store them in their bodies. 

Those with venom have fangs or stingers to inject their prey with venom. Some creatures, such as spiders and scorpions, can produce poison and venom.

If you’re bitten by one of these creatures, it’s essential to know whether it has a poison gland or not because treatment varies depending on what type of animal is involved.

Characteristics of Poisonous Animals

All poisonous animals have one thing in common: they can all kill you. But there are different ways that they can do this.

Some animals, like the poison dart frog, have poison on their skin that they use to defend themselves. Others, like the king cobra, have venom in their fangs to kill their prey. 

Some animals, like the box jellyfish, also have poison on their tentacles that they release when a human or animal touches them.

Other poisonous animals include the lionfish, pufferfish, blue-ringed octopus, and aconite mushroom.

The difference between venomous and poisonous is that while all venomous animals have poison, not all poisonous animals carry venoms.

What is Venom?

Venom is a secretion of an animal, typically a snake or arthropod, that is delivered by biting or stinging. It generally contains toxins that cause injury or death to the victim.

The main difference between venom and poison is that venom is injected into the victim while poison is ingested.

Some animals are both venomous and poisonous; snakes use their venom for hunting but can kill prey with their poison.

You might think that all snakes are venomous because they bite with their teeth, but not all snakes have fangs or other methods of injecting a victim with their deadly toxin.

Types of Venomous Animals

There are two types of venomous animals- those that have a stinger and those that don’t. Animals with a stinger, like bees, wasps, and hornets, can only sting you once because they lose their stinger.

These animals have venom glands connected to their stinger that inject the venom into their victim.

Animals without a stinger, like snakes, spiders, and scorpions, can bite you multiple times because they don’t lose anything.

These animals have fangs connected to their venom glands that inject the venom into their victim.

The difference between venomous and poisonous animals is how they deliver the venom to their victim. If an animal has a stinger, it uses it once and then loses it.

If an animal doesn’t have a stinger, it can use its teeth or claws to strike the victim repeatedly and then continue biting them.

Characteristics of Venomous Animals

Venom is produced in specialized glands and delivered through fangs, stingers, or spines.

The venom then travels through the animal’s body to the site of the wound, where it begins to break down tissue. Venomous animals are usually faster, stronger, and more agile than prey.

Some venomous animals have bright colors that warn predators to stay away. Other features include a wider mouth, rough skin, and a thick tail.

These characteristics make venomous animals good hunters because they can ambush their prey before delivering a fatal dose of poison into the victim’s bloodstream.

Venomous animals include rattlesnakes, black widows, scorpions, sea snakes, and king cobras.

While some plants may be poisonous, they lack the active enzymes and proteins that produce toxins. However, plants will still irritate your skin or cause nausea if you eat them!

Animals with tentacles like jellyfish or octopuses inject poison through stinging cells called nematocysts located on the tentacles.

Jellyfish use their tentacles to get food, while octopuses use them for defense against larger predators such as sharks.

Animals with both venom and poison

Some common examples of venomous animals include snakes, spiders, and scorpions.

These animals have specialized glands that produce venom, which is injected into their prey using fangs or stingers. On the other hand, poisonous animals don’t have venom-producing glands.

Instead, they secrete toxins from their skin or other body parts that can be harmful if ingested or come into contact with mucous membranes.

These poisonous animals include frogs, toads, and some fish. For an animal to be classified as poisonous, it must either ingest or come in contact with a toxin and die within 24 hours.

The animal doesn’t need to inject this poison directly into its victim’s bloodstream. An excellent example of this type of poison is a bee sting.

When bees use their stinger on prey, it injects tiny barbs into the victim’s skin along with their saliva.

The venom in the bee’s saliva causes swelling, tissue damage, and allergic reactions like anaphylactic shock (a severe allergic reaction). 

The venom contained in these barbs is not fatal on its own; however, because they have many different types of chemicals that cause various effects on the body (such as clotting blood), it makes them difficult to treat without professional help.

Many animals in the world have both venom and poison. Some of these animals are snakes, spiders, scorpions, and centipedes.

These animals can be dangerous to humans because they can inject their venom into our bodies. 

Difference Between Venomous and Poisonous

Most people think they are the same, but there is a big difference between venomous and poisonous.

Venomous creatures have a delivery system for their toxins, whether fangs, spines, or stingers.

On the other hand, poisonous animals do not have a delivery system and rely on you coming into contact with them to be poisoned. 

A venomous snake will bite and inject you with its poison, whereas a poisonous frog won’t hurt you unless you eat it.

A person allergic to bees can also get stung by one without being harmed, but if they were allergic to frogs, they would die because the frog’s toxin has no way of entering your body.

When in doubt, remember that only venomous animals are dangerous, while poisonous animals pose a threat only when consumed.

For example, most jellyfish are poisonous (and deadly). Still, they do not possess any means of delivering this poison-instead you need to come into contact with the tentacles of a jellyfish to feel their effects. In contrast, scorpions use their tail stingers to provide lethal doses of venom. 

Other venomous creatures include snakes, spiders, and insects such as hornets and mosquitoes.

One type of creature that isn’t usually considered venomous is a catfish, which doesn’t have a delivery system but still relies on you touching it to be harmful. 

The critical point here is that both types of creatures are harmful differently.

At the same time, many harmless animals, such as bears and sharks, are sometimes considered poisonous due to their potential to cause harm by accumulating toxic substances from the environment.

These animals typically cannot deliver enough poison in one instance to cause damage.

How to Handle Venomous Animal Bites?

The venom can cause us to feel pain, swelling, and even paralysis. If we are bitten by one of these animals, it is essential to seek medical help immediately. Medical professionals will need to identify which type of animal bit you.

They will also use antivenin if you were bitten by a snake or other creature with venom. Antivenins work by using antibodies against toxins from animals like snakes or spiders.

You should also see a doctor if you are bitten on your hands or feet because those parts of your body may swell too much for you to move without help.

In some cases, bites from certain animals may lead to an infection at the bite site. It is important not to scratch or put pressure on any infected areas and to get checked out by a doctor as soon as possible.


The terms are often used interchangeably, but there is a big difference between venomous and poisonous. Venom is injected into the body, while poison is ingested. 

The venom acts quickly, and its effects are localized; while poison can take a while to kick in, its effects can be widespread.

So, the next time you hear someone say they’re afraid of snakes because they’re venomous, you can correct them – snakes are poisonous, not venomous!
