Nature is filled with a plethora of animals and insects that have their own unique defence mechanisms. In fact, nature has gifted them different kinds of poisons in order to protect themselves from external threats, thereby increasing their longevity.

1. Black Widow Spider

Black Widow Spider is famous for its bite that is highly venomous as they inject a powerful neurotoxin into the human body. This neurotoxin will create cramping and strong muscle pain. Indeed, this bite can be compared with a pinprick that goes deep which will be followed by stiffness and intense burning spreading all over the body. Nausea, sweating and even breathing difficulties will also manifest as symptoms of the bite. Even though the risk of death can be thwarted with the use of the right medications, pain usually lasts for a number of days.




2. Box Jellyfish

Considered to be one of the most dangerous stings in nature, Box Jellyfish’s attack can cause piercing pain instantly. This marine creature’s tentacles will inject a potent poison that will affect our nervous system, skin cells and even heart. Muscle cramps, welts and powerful burning sensations will also manifest as symptoms. In some extreme cases, cardiovascular failures and deaths have been reported as well. The bottom line is that most people who have encountered the bite of jellyfish consider it to be the most painful experience in their lives.



3. Bullet Ants

The venom of bullet ants can create throbbing and burning sensations that can last for almost a day. The pain is often explained as the feeling of being shot by a bullet. Shaking, sweating and even temporary paralysis will also follow as symptoms. In short, even though the bite is rarely life threatening, the sting of bullet ant is widely considered as one of the most painful amongst insect stings.
