Let's make a distinction here between "venomous" and "toxic."
Some butterflies are toxic: if you eat them, they'll poison you. In many cases, this is because when the butterfly was a caterpillar, it ate a plant that contained a poison and stored the poison up in its body. The monarch butterfly is one example: monarch caterpillars love milkweed, many species of which contain cardiac glycosides that disrupt the functioning of the heart.
However, no butterflies are venomous: they can't bite or sting you and inject poison (I'm not aware of any butterflies that can bite at all).
As long as you're not eating them, they're pretty harmless.
Well, poison ivy itself isn't poisonous - it's the urushiol oil is the problem. One nanogram (that is, one billionth of a gram) is enough to affect an individual. Only roughly 15% of the world's population is NOT allergic to urushiol oil. So, be careful! Don't touch poison ivy, for it is better to be safe than sorry.
The box jellyfish is considered one of the most venomous marine creatures in the world, containing toxins that can be deadly to humans. Another highly poisonous organism is the golden poison frog, which secretes a powerful neurotoxin through its skin.
One scientific question about butterflies could be: How do butterflies navigate during migration over long distances?
actually the butterfly defend by caterpillar : hiding,camouflage and there eyespots may scare off some predators butterfly: they have strategies like looking like a dead leave and other like the bark of a tree. Some butterflies are poisonous (monarchs) so when a bird swallows it, it then vomits a lot and learns to never eat butterfly again.
Poison can have a variety of smells, but some common ones include a bitter or metallic odor. It can also sometimes smell like chemicals or rotten eggs. Recognizing poison by smell alone can be difficult, so it's important to also look for other signs such as unusual colors, labels indicating toxicity, or unusual packaging. If you suspect something is poisonous, it's best to avoid contact and seek help from a professional.
According to an Internet search, there is no butterfly that is so poisonous that it would kill a human. There are butterflies that are extremely distasteful to birds and other such predators due to the larva's consumption of poisonous plants. The Monarch butterfly is a well-known example of that. The larva eat milkweed.
There are poison medicines. Suppose you are the one taking the medicine. You shouldn't overdose it or else the medicine could come poisonous. Suppose your not the one taking the medicine. The medicine is just lying on the table. Don't drink or eat it because you don't know if it's poisonous.
Poison Dart frog.
Because they are poisonous so they might die if they touch one and get infected with the horrible poison.
There is nothing known to be poisonous to squirrels. It is illegal to poison a squirrel so therefore, they are no known poisons for squirrels.
There are many things that are poisonous to humans. Curare is one. Botulism is another.
NO. You cannot eat a poison dart frog. It is POISONOUS! If you eat it you will DIE. --------- First of all the question was just if you could eat a poison dart frog which you can (if you can catch it and don't mind the taste) but it would be extremely stupid as they are poisonous and some of the species (not all) even deadly. If you insist on tasting this delicateness you should find one which is born in captivity as these are not poisonous.
There are at least 4 snakes I can think of that are black and yellow, you would need a much better description to figure out which one it is; and it helps to know 'where' you saw it (part of the world).NOTE: All snakes are poisonous, even if the 'poison' is a type of bacteria to aid in digestion; you can react badly to any of them - IE: the safe rule, if you treat them all as poisonous you are more likely to not be bitten by a poisonous snake.
Cyanide is the poison found in green almonds, though the almonds sold in shops is unlikely to be poisonous unless eaten in a massive quantity at one sitting.
Giving some to whatever you're trying to poison and seeing if it dies. It's more a biological experiment than a chemical one.
A poisonous animal is one you should not bite because its body has poison on it or in it.A venomous animal is one that should not bite you because it makes venom that it injects into its prey.
Well,poison dart frogs do not have venom. It is there slimy poisonous skin that gives it its name. If poison dart frogs are bred in captivity they do not have poisonous skin,is what I heard. Poison dart frogs are not the best pets. :)
