One of the most dangerous animals in Africa, this animal has a history of attacking humans. As a herbivore, this animal doesn’t want to eat you, but it is very aggressive and unpredictable and may attack you even without being provoked. Males weigh around 3,310 Ibs and females 2,870 Ibs. They are semi-aquatic mammals, spending much of their time in rivers, lakes, and mangrove swamps.
Despite their large and heavy form and short legs, they are able to run 19mph. During the day, they cool off by staying in the water or mud. At dusk, they leave the water to eat grass in solitary.
Fire Ant
Killing around 50 people a year, this is the most aggressive species of ants. Their bite can send you into anaphylactic shock and in some cases, death. They are found in more rural or remote areas.
This invasive species costs the US $5 billion every year on medical treatment, damage, and control in infested areas. They also cause $750 million in damage every year to the agriculture and farming industries. More than 40 million people live in infested areas in the southeastern US.
Assassin Bugs
With a name like that, you know there’s a reason to worry. These bugs' bite spreads the deadly Chagas disease, which can cause severe damage to your body. In 2015, it was estimated that 6.6 million, mainly in Mexico, Central America, and South America had the disease and that 8,000 people died from it.
Most people who are infected are not aware of the disease’s presence. At the onset of the disease, symptoms may be mild, including fever, swollen lymph nodes, or swelling at the location of the bite. In rare cases, the disease can lead to heart failure, an enlarged esophagus and colon. If that’s not freaky enough, they are also called the kissing bug, as they bite you near your lips.
Yellow-Bellied Sea Snake
As its name suggests, this snake is easily recognizable thanks to its warning sign coloring. With a black back and a bright yellow belly, this creature practically screams "Get away from me". These snakes are found in tropical waters in oceans around the world, except for the Atlantic.
They are one of the most widely distributed snakes. While antivenom is available in Australia, you don't want to provoke one of these into testing the cure's efficiency.
Pitohui
Not to be fooled by its beauty, this bird has venom which is similar to the King Cobra, but more concentrated. Just one drop of their highly potent poison can kill three people and paralyze all the muscles in your body.
Touching this bird can cause harm as its skin and feathers contain poison. Its poison is similar to that which is found in the Poisonous Dart Frog. It is believed that the poison provides the birds with a chemical defense against predators such as snakes and humans. The birds don’t produce the toxin themselves but acquire it from the beetles they eat.
