The scorpion is a small animal that may seem harmless at first glance, but can cause serious harm if it feels threatened or attacked. With its venomous tail, it is capable of inflicting painful and potentially deadly stings.

Scorpions can be found in many regions of the world, and some species are more dangerous than others. Symptoms of a scorpion sting can vary depending on the species and severity of envenomation, but may include intense pain, cramps, convulsions, increased heart rate, and respiratory failure.

Although deaths from scorpion stings are relatively rare, they still occur in some regions of the world, particularly in Africa, Asia, and Latin America. Victims are often children or elderly individuals, who are more vulnerable to the effects of the venom.

Yet, despite their reputation as killers, these majestic animals play an important role in the coastal ecosystem by regulating the fish population and maintaining ecological balance.

Number 1 – Mosquito

The deadliest animal on the planet may surprise some, as it is neither a lion, nor a shark, nor a crocodile. In fact, the deadliest animal is much smaller and more insidious: it’s the mosquito.

Every year, mosquitoes transmit deadly diseases to millions of people worldwide, including malaria, dengue, chikungunya, and Zika virus. Malaria alone kills nearly 400,000 people each year, mostly in sub-Saharan Africa.

Mosquitoes are so dangerous because they carry deadly diseases and can easily spread them. Female mosquitoes need blood to lay their eggs, and they can bite animals and humans to obtain this blood. If the mosquito is infected with a disease, it can transmit it to the person it bites.
