is the centipede's  tail poisonous?

No, the tail is not poisonious. The head isn't poisonious either, it's venomous, but that's just a technical detail (venom is injected with fangs, stinger, etc, poison isn't). But centipedes have two fangs on the bottom of the head. They can inflict quite a bit, especially the larger species. There could be some reason for people to think the tail is venomous though, there are two long "tails" at the end that look quite bad, but aren't. The tail also looks like it has antenna, so it can be confused with the tail. Also, anyone foolish enough to pick a centipede up by the tail is very likely to get bitten anyways. Centipedes are very fast and can bend backwards on themselves. But it is not the tail that is venomous.

The poison from the skin of the world's most poisonous known creature-the tiny, 1.5-inch, Golden Poison Frog (Phyllobates terribilis)-kills the monkey.\n\nAn average P. terribilis contains about one milligram of poison, which is enough to kill 10,000 mice-perhaps enough to kill 10 to 20 humans if the poison reaches their bloodstreams.\n\nThis extraordinarily lethal poison (a steroid alkaloid, called batrachotoxin) almost does not occur in nature. We have found this poison only among three poison frogs in Colombia and two poison birds in Papua, New Guinea.\n\nThe yellow frog stores the poison in skin glands, as do most frogs. Due to their poison, frogs taste awful to predators but P. terribilis' poison kills whatever eats it-except for a snake (Liophis epinephelus). This snake is resistant to the frog's poison but not immune.\n\n"We fed one juvenile frog to a snake and the snake showed great distress and was rendered helpless for several hours," says John Daly, chief of the National Health Institute's bioorganic chemistry laboratory.\n\nThe poison frogs are perhaps the only creatures immune to this poison. The poison attacks the sodium channels of the cells. Through the ages, the clever frog has evolved special sodium channels that the poison can not harm.

The scorpion, except if the centipede can run away real quick or do a bicycle kick!

Its poisonous. Its multiple hydroxyl groups can pass it off as a sugar into tissues where it can wreck havoc.

It is hard to say which animal would get this prize. A poisonous animal carries harmful chemicals called toxins. Usually, these toxins are used for defense, and are stored in the skin or in special glands. Compare these creatures to venomous animals, which deliver their toxins by stinging, stabbing, or biting.\n\nPoisonous creatures don't intend to hurt other creatures, which is why they have bright colors and markings that send a clear message: "Don't touch!" If a predator ignores that warning, he might not get a second chance. One swallow, or even a little taste testing, and it's all over. The toxin will stop the heart or lungs from working, and death will follow.\n\nThe poison arrow frog and certain salamanders would have to top most people's list of "The World's Most Poisonous Animals." Just two micrograms of toxin from the poison arrow frog is enough to kill a human. A "microgram" is a very small amount. The ink in the period at the end of this sentence will weigh around six micrograms.\n\nWhat about venomous animals? A good example of defense can be found in stonefish. They store their toxin in gruesome-looking spines that are designed to hurt would-be predators. This homely creature will win no beauty prize, but deserves honor and respect for being "The World's Most Venomous Fish."\n\nToxins also are designed to kill prey or, at least, slow them down. This is the tactic used by many snakes. The prize for "The World's Most Venomous Snake" goes to the inland taipan of Australia. But the top prize, "The World Most Venomous Animal," should go to the box jellyfish, which is found in the waters around Asia and Australia. They have long tentacles with stings at the very ends.\n\nHospitals often carry medicines that work against venom, but treatment has to be very fast to counteract the toxins of these prize-winning creatures

Just that I am terrified  of them ,and it is a cold blooded reptile. Most change colors of the surface they are on. Good things about them are..they help control a lot of the insects that are harmful to man such as misquitoes, flys ect. there is only one known poisiones in the U.S. that is the Gilla Monster found in the deserts of the southwest USA. The rest you can play with and maybe get a painful bite.

The deadliest and most venomous snake is without a doubt the Rhinocerous Viper of Africa. Man, that thing is SOOO colorful! Looks nice, but it is DANGEROUS. Watch out for it next time you visit Africa! \n\nGold is impossible to decompose, by the way.

It depends on the spider...if it is not poisonous, you will probably get something that looks like a mosquito bite. Be careful though, you can get a secondary infection(cellulitus), that may require antibiotics. It looks like a regular bite, but the skin around it gets red and inflamed. If you suspect a spider is poisonous, you should head to the ER asap!

You don't mention where it was found so that makes ID difficult; sounds like a Scolopendra. Look through these pics to see if you find a match. Some are poisonous; some are not.\n\nhttp://images.google.com/images?svnum=10&hl=en&lr=&as_qdr=all&q=+%22scolopendra%22+centipede&btnG=Search

That reminds me of one of the ancient mythologie (greek, I think) called the Ouroboros---the snake eating its own tail.  No end, no beginning.    Good point on the "circular arguments".....

The poison dart frog is a more dangerous species than the Cane toad. It seems that although all toads are atleast mildly poisonous as has been stated, frogs can have a much more toxic and lethal poison than a toad. There are 5,296 species of anura, the order than frogs and toads are in, and the toads are in the family Bufonidae.

black mamba, from kill bill vol II :)~\n\nwell i actually looked it up and 2 sources say it is this inland taipan snake...\n\n1) Fierce Snake or Inland Taipan (Oxyuranus microlepidotus ), Australia. The most toxic venom of any snake. Maximum yield recorded (for one bite) is 110mg. That would porbably be enough to kill over 100 people or 250,000 mice. These rare snakes are vitually unknown in collections outside of Australia.\n\nBlack mamba actually comes in 11th place :(

Depends on how the head was raised, what shape the head was, and exactly what the pattern was. if the head was raised in a curved manner, it was not a poisonous snake(especially if you could tell the head was not arrow head shaped). If the head was simply tipped upward, it was probably a poisonous snake. Now as for the checkerboard pattern, it sounds like a rattlesnake to me, assuming it was a venomous snake, But copperheads also have that pattern sometimes. nevertheless, assume it was venomous and deadly.

I don't think it's really possible to know that without testing it. But I would guess that your idea is right, because there would not be enough venom to kill an animal that large. It would probably make it sick. But then again, a whale, or any other really large animal, would react differently to the venom. It might kill it despite the size.

If you're talking about what I think you are, then it is not dangerous at all. It can spray a nasty vineger stuff to scare off predators, which would hurt if you get it in your eyes. But the only thing that really needs to be afraid of that is a cricket.\n\n\nHeh, sorry, wrong picture. I was in a hurry to get to school. So yeah, it sprays from a gland at the base of the tail. It's called a vinegarone, or sometimes a whipscorpions. Whipscorpion can sometimes give you the wrong thing though, like the picture I gave earlier. Try the other link or look up some more.

It wasn't a black widow spider which are poisonous.They are dark black and shiny not hairy with white stripes on the leg. They have a red hour glass shape on the belly.I believe it might be just an ordinary jumping spider found in most homes non poisonous.

The deadliest poison of an arachnid belongs to the death-stalker scorpion. It is several times more potent than the deadliest poison belonging to a reptile - venom of a fierce snake found in Australia.
