Brown Recluse Spider
In addition to the brown recluse spider, which makes our list of the world’s most dangerous animals, we have the black widow spider. This spider, which is native to North America, is known for its exceptionally terrible venom. In reality, it contains so-called necrotic venom, which can induce necrosis, or skin death, that you may or may not be able to recover from depending on the severity… When a brown recluse spider bite results in a rupture of the red blood cells, it is considered to be a particularly heinous injury. If you come face to face with a brown recluse spider, you’ll identify it because it will be brown and spider-like in appearance, with a distinctive marking on its abdomen in the shape of a violin. It will also have six eyes instead of the eight that typical spiders have (so not only will it have eight legs, but it will also have eight eyes all the more to watch you with!). This spider, like many others, will only bite if it feels threatened. However, because it is an exceedingly sensitive creature, it may interpret your efforts to tidy up the stack of old papers in the garage, where it has made its home, as threatening behavior. They are reclusive by name and reclusive by nature, and they don’t appreciate humans invading ‘their’ space wherever they happen to be resting their heads, so clean up after yourself at your peril.
Sandfly
Sandflies may only appear to be a minor nuisance during a day at the beach, but, like so many other insects, they have the ability to cause serious illness. In this tiny fly, which measures roughly 2mm (3mm on a good day), is carried a protozoa, which is much smaller and has microscopic proportions. The protozoa is a type of microbe that is even smaller than the fly. Despite the small size of this fly, which is known as a disease vector, the disease it produces is far from trivial because it is carrying something else (the protozoa) that causes a disease that would otherwise be impossible to manifest on its own. The condition in issue is known as Leishmaniasis, and it can manifest itself in a variety of different ways. In some cases, it can cause massive skin ulcers, destruction of the mucosa of the mouth, nose, and throat as well as swelling of the spleen and liver, depending on how it manifests itself. All of these things are horrifying, and they all result in apparent and serious abnormalities (and the mental health problems that come with that). Female sandflies are the only ones who carry the disease, and they are the only ones that transfer it by their bite. They are found in the inter-tropical and temperate regions of the planet, and they are most active in the evenings and at night, according to experts.
