Animal bites and scratches that break the skin can sometimes cause infection. Some bites need stitches while others heal on their own. Rarely, bites from wild animals can lead to rabies, a life-threatening infection. Bats, raccoons, skunks, and foxes cause most rabies cases.

Treating bee and wasp stings depends on their severity. The majority of problems that require medical attention come from an allergic reaction to the sting. In most cases, complications from that reaction respond well to medications -- when given in time. 

The most familiar sting is from honeybees, but some wasps and other insects can also sting. Yellow jacket wasps are the most common cause of allergic reactions to insect stings in the United States. The bee’s stinging apparatus consists of a sac of venom attached to a barbed stinger. When a bee or wasp stings, the sac contracts, pumping venom into the tissue. Wasps are more aggressive than bees, and they may sting you multiple times, resulting in more swelling and pain.

Carbon monoxide, or “CO,” is an odorless, colorless gas that can kill you. CO is found in fumes produced any time you burn fuel in cars or trucks, small engines, stoves, lanterns, grills, fireplaces, gas ranges, or furnaces. CO can build up indoors and poison people and animals who breathe it. The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO it can make you pass out or kill you. People who are sleeping or drunk can die from CO poisoning before they have symptoms.

Less aggressive than some common species of wasps, with the exception of the Africanized honey bee, bees are an essential part of our ecosystem. With their ability to pollinate flowers, fruit trees and other food-producing crops, not to mention the ones that make honey, bees are an important insect for farmers and our environment.

However, for people who are allergic to bee stings and those who are not, the threat of being stung can be scary. And, since different bees tend to be more threatening than others, it's important to properly identify what type of bee you're seeing before you take any action.

Despite the fear they put in many people, snakes are actually under threat in their own natural environment. Between the pressures caused by invasive species and the gradual destruction of their habitats, it’s no wonder that there are a number of snakes that are threatened with extinction.

Meet the rarest snakes in the world. These animals are not only mysterious and dangerous, some species are also very strange.

Snakes are highly effective predators, and some species that rely on venom for hunting and self-defense can deliver a bite toxic enough to kill animals many times their size. The bite of a king cobra, for instance, can kill an elephant.

Toxins are all around us. Whether it's the car fumes you inhale, the frozen dinner you eat, or the negative thoughts you have at work, toxins are everywhere. Our bodies are designed to handle daily toxic exposures through our detoxification and elimination organs, such as the liver, colon and kidneys, which do a pretty good job keeping us healthy. That being said, the things that we consume on a regular basis often raise the biggest concerns because of toxic accumulation. Anything that enters our bodies through direct contact with our mucosal membranes, inhaled into our lungs or touches our skin for long periods of time has the highest chance of entering our blood stream and influencing our health, for good or bad.

Natural toxins are toxic compounds that are naturally produced by living organisms. These toxins are not harmful to the organisms themselves but they may be toxic to other creatures, including humans, when eaten. These chemical compounds have diverse structures and differ in biological function and toxicity.

Poison is any substance that is harmful to your body. Many different types of poison exist. Poisonous substances can be products you have in your house. Medicines that aren’t taken as directed can be harmful. There are several ways you can be exposed to poison. You could breathe it in, swallow it, or absorb it through your skin. Poisoning can be an accident or a planned action.

Scorpions are predatory arachnids of the order Scorpiones. They have eight legs and are easily recognized by the pair of grasping pedipalps and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous sting. Scorpions range in size from 9–12 mm (0.35–0.47 in) in Microtityus minimus to 23 cm (9.1 in) in Heterometrus swammerdami.

The evolutionary history of scorpions goes back to the Silurian period 435 million years ago. They have adapted to a wide range of environmental conditions, and they can now be found on all continents except Antarctica. There are about 1,750 described species, with 13 extant (living) families recognised to date. Their taxonomy is being revised in the light of genomic studies.
