Many snakes are venomous enough to kill humans, so if you see one that’s not in the cold list, you might get scared. But there are many other types of animals that can poison us too. Check out this list of some venomous and poisonous animals, to familiarize yourself with what you should be wary of.

 Puffer Fish
Puffer fish, the second most poisonous vertebrate in the world, inhabit all tropical waters in the world. Their Venom is potent enough to kill humans. Drinking Puffer fish’s liver and kidneys could potentially send one to the hospital; however, a well-cooked ‘Fugu’ dish made from puffer fish can also be bought in restaurants. The name of this dish translates to ‘dangerous or fatal meal.’
 Poison Dart Frog
Poison dart frogs are unique in the world. They have many different patterns and colors, among other things, but their most dangerous form is the golden dart frog. This type of frog contains enough venom to kill 10 adult men!
 Brazilian Wandering Spider
Brazilian wandering spiders are the most venomous spider in the world, with a powerful bite that can cause death even to humans. Luckily, there’s an antidote available for the venom they inject so you don’t have to worry! These spiders live in dense forests of Brazil and Amazonia. Unlike other spiders, Brazilian wandering spiders won’t use webs to catch their prey – they walk around looking for it on the floor. They predominantly feed on insects and other spiders with bigger goals than surviving. The spray from Brazilian wandering spiders causes intense pain, muscle control loss and inflammation. If you’re bitten by these creatures – get immediate medical help!
 Inland Taipan
The inland Taipan is a snake that can be found in central Australia. They have enough venom to kill up to 100 adults with just one bite and are more shy than other snakes. They’re more likely to avoid contact with humans because they prefer their own habitat and are not aggressive.
 Death Stalker Scorpion
Death stalker scorpions are one of the deadliest species of scorpions that inhabit across the Middle East and North Africa. They’re aggressive, and their neotrotoxin venom can be deadly even to humans if bitten. The bite from a death stalker scorpion is incredibly painful and can cause severe heart issues. If you’re unfortunate enough to be bit, hasproceding immediately is highly recommended. Delaying could cause serious health issues, even death.
 Stone Fish
While it may be hard to find stone fishes, they are a highly dangerous species that can lead to fatal reactions. Information on these fish is scarce as well because they lurk in mud or sand on ocean floors. They contain 13 sharp spines that sting quickly and cause extreme pain and paralysis. Without proper treatment, the chance of death is high.
Marbled Cone Snail
The lowly marble cone snail is the most venomous cone snail to ever live. They’re found in the Indian ocean, and they’re able to use their deadly venom all over the world. Sadly, there’s no antivenom for their sting, as it’s believed to cause serious conditions such as loss of coordination, difficulty in breathing, heart failure and double vision. The most serious cases can even lead to a coma or death.
 Blue Ringed Octopus
The blue ringed octopuses are members of the octopus family and measure only 20 cm in diameter. They are extremely dangerous and can produce two types of venom through their saliva. The first type of venom is use to catch prey, while the second type is called tetrotoxin; which can be deadly even to humans. As far as toxicity goes, only 25 grams of blue-ringed octopus venom is enough to paralyze 10 adults; whereas other poisonous animals’ bites usually cause some level of pain. However, with the blue ringed octopuses, it’s not so bad. And as a result, if not treated immediately after the bite, symptoms can include numbness, vomiting, swallowing difficulty breathing or nausea
 King Cobra
The king cobra is a world-famous and longest venomous snake. An adult king can reach about 18 feet in length, but this species of snake has been known to grow as long as 20 feet before dying. They’re also capable of swimming one mile per hour, which makes them masters of avoiding trouble. Just like many other snakes, they are capable of injecting up to 5 times more venom on a single bite, which is highly deadly and may kill up to 20 grown men.
 Box Jelly Fish
Box jellyfish are the most venomous creature known to mankind. They inhabit in the Indo-Pacific region and have been reported to kill more than 100 people every year. These cube-shaped jellyfish have around 15 tentacles on each side of their body, some of which can reach up to 10 feet in length. These tentacles also contain more than 5000 venomous stinging cells and they can affect the nervous system and heart, most often with deadly results.
