The only known predator of the world's most poisonous frog (Phyllobates terribilis) is a snake, Liophis ( Leimadophis ) epinephelus. This snake is resistant to the frog's poison but not immune.

The great white shark and saltwater crocodile have gone longer than any other predator on the planet without evolving.  That means they are the best there is at what they do.  As for poision, some types of sea snakes have venom up to 10 times as strong as rattlesnake venom, but they are usually quite docile.

Where you live will help people answer your question.\n\nLink below loads slowly but is worth the wait.  In Northeast US, garter snakes and black rat snakes are starting to show up - they are beneficial - they eat rodents.\n\nWhere I live - timber rattlers and copperheads are the only two poisonous snakes.  These snakes would rather escape than confront, so in hot weather, I just pay attention to where I put my hands and feet, so I don't disturb them.

The Zebra snake is also known as the western barred spitting cobra. This African snake is highly poisonous and derives it name from the black bands that encircle its body and tail.

The issue is still very much controversially discussed among biologists.  But it is true, the strongest venoms are found in Australian snakes.  Even seasnakes with their hgihly effective and potential venom are of Australian origin.  \n\nVenoms are highly diverse in their biochemical composition throughout the recent snake taxa (or taxonomic groups, like "family", "genus" etc.), which makes developing anitoxins so challenging, but which also offers great possibilities in drug development in biomedical sciences.  what it tells us in regard to your question is that possibly the composition of the toxins can hint at their evolutionary origin.  it is, what in phylogenetic research (the study of the evolutionary relationships of organisms) is referred to as a characteristic.  \n\nOne thing you have to keep in mind is that Australia is geographically separated from other continents.  Unless living in the water or the air and being able to migrate long distances across long stretches of ocean, species will neither get nor out of Australia very easily (the seasnake being a case in point; it made its way all over the south sea).  In other words, what is there, will evolve further there.  \n\nVenoms usually evolve in a complex process also known as co-evolution.  What determines change in the venom's composition and strength is the evolutionary adaptations of those organisms that get exposed to the poison.  In other words, if a snake evolves a strong poison, but its main prey evolves an immunity to the toxin in response, a new and stronger poison would be necessary.  And so, in co-evolution, certain traits can become extremely "heightened".  \n\nNow, given that Australia is such an isolated part of the world (a giant island), co-evolution is likely to occur more often and easily.  Elsewhere, a snake could simply try to migrate on and find other food. But more importantly, the diversification of snakes has pretty much one point of origin.  It is one "monophyletic" group.  The family of Australian snakes is the Elapidae.  And these critters now evolve with already strong venom.  You can see how the isolated geographic situation will intensify the process and produce strong venoms.  This is also supported by the fact tha not only snakes but all other venmous critters have evolved more poisonous in Australia than elsewhere in the world.  \n\nAnd ultimately, that means that one of the former comments has a valid point: Australians are tough to kill!  Only that I am not thinking of human beings...\n\nHope that helps.

Deadly is a misleading term, my friend, making it difficult to answer your question.  First there is a distinction between "deadly" and "poisonous" and "venomous".  Deadly spider would entail a study as to how many people have died as a result of an unfortunate run in with the animal or the odds of surviving a bite from the spider.  Then the venom vs. poison debate.  All venom is poisonous, but not all poisons are venom.  If we are discussing spiders and their danger to humans, then we are most likely talking about "venomous" rather than "poisonous".  So a venomous spider would mean one that has the most potent and/or most effective venom.  So here are your answers:\n\nThe Brazilian Wandering Spider is the world's most venomous and deadliest spider.  This is in largly part due to the fact that the spider is very fast, very aggressive, very nervous, does not use "webs" as their hunting tool (note the word "wandering" in it's name), and can and will bite humans.  This spider has the most toxic and deadliest venom known to the world, giving it the title as world's most venomous spider.  It is a South American spider but has sometimes been known to be located in crates of bananas being shipped to the U.S. and other countries, so be careful.\n\nHowever, the Australian funnel-web spiders are among the deadliest spiders in the world in the effect their bites have on humans.  The venom they carry is called atraxotoxin, and is one of the most deadliest toxins known to man.  Only a few of the Australian species are dangerous though, and of the deadly varieteis, the Sydney funnel-web is most encountered.  They are only located in Australia unless kept as pets or for observation elsewhere in the world.\n\nI hope this helped.

Mongoose, other snakes, predatory birds, some lizards and even some species of trapdoor spiders have been known to catch and eat small snakes\n\n(Thanks tbech7430!!)

not sure..but you should definitely read the book "Salvation on Sand Mountain" by Dennis Covington.  It talks about snake handling and it's a very good book.

Chuck Norris\n\nContrary to popular belief, Chuck Norris, not the box jellyfish of northern Australia, is the most venomous creature on earth. Within 3 minutes of being bitten, a human being experiences the following symptoms: fever, blurred vision, beard rash, tightness of the jeans, and the feeling of being repeatedly kicked through a car windshield.

New Zealand has no land based snakes either native or introduced.\n\nHowever due to New Zealand’s sub tropical climate it is visited by two species of sea snake.\n\nThe yellow-bellied sea snake. The most widely distributed sea-snake in the world. An infrequent visitor with just 35+ sightings around New Zealand shores since 1930. \n\nThe banded sea krait. Comes from India and South-east Asia through New Guinea, Australia and the Pacific Islands. Rarely seen here.\n\nBoth species of snakes are highly poisonous but, due to their size, can't penetrate human skin.

A cobra is much more poisonous than a rattlesnake. If a rattlesnake bites you, you have a pretty good chance of living through it without any medical attention, although it is advisable to get medical attention.\nIf you are bitten by a cobra, medical attention and antivenom are necessary immediately.\nA bit of advice. First aid used to recommend the application of a tournquet between the bitten extremety  and the heart plus making an X incision 1/4 inch long and deep on the fang punctures. This is not a good idea as the incisions can cause more damage than the snake bite. The suction cups in a snakebite kit are good for sucking out the poison. If you try sucking it out by mouth, if you have a sore or some wound in the mouth, you can get poisoned, too.\n Application of an elastic bandage over the bite helps to prevent the poison from spreading through the body. Keeping calm is also a good idea as if the bitten person gets excited, the pulse rate goes up spreading the poison at a much more rapid pace.\nAbout 20 or so years ago, it was thought that electric shock, such as from a taser, would destroy the toxicity of the poison. I haven't heard anything about that for many years, so I don't think it worked very well.\nBe cautious around areas where there are known to be snakes, know what their habitat is and when they are likely to be about. \nIn the spring and late summer here in the northern U.S., the snakes shed their skin. At that time, they are the most dangerous because they can't see well.

The absolutely most poisonous plant-like organisms are any number of mushrooms (yes, I know they're fungi, but they look like plants) that grow wild-many of them are fatally toxic with nothing more than a lick.  The greatest number of deaths occur from bee stings (anaphylactic shock)- Botulinum toxin is the most toxic substance on Earth, as mentioned.  Copperheads are more venomous ounce for ounce, but rattlesnakes are more dangerous because of the amount injected.  But you are asking "lethal", so- The cyanogenic plants, such as wild cherries, peaches, etc- If the leaves are cut correctly, or frozen on the vine, they generate high levels or hydrogen cyanide.  A handful of these leaves can kill a cow or horse, so I would say that those are the most lethally toxic.
