The scorpion (Scorpiones) is a well-known arachnid that falls in the same category as spiders because they have eight legs. There are more than 1,400 scorpion species worldwide that have adapted to different climates and diets.
They typically become an easy target for predators like owls, lizards, and snakes; however, they’ve developed several defense mechanisms – the most notable being their sting. All scorpions are venomous and will utilize their sting for defense and/or to paralyze their prey for a meal.
9. Chilean Recluse Spider
The Chilean recluse spider, or Loxosceles laeta, is number nine on the top 10 most venomous animals in the world. This spider’s venom can be deadly, depending on the size of the spider and the size of the victim.
If the venom is not strong enough to kill, it will cause the victim’s skin tissue to dissolve and cells to die, resulting in amputation. The effect of this venom is 10 times stronger than sulfuric acid.
8. Black Widow Spider
The black widow spider, which can be found in different species under the genus Latrodectus, is known for its dangerous bite. The term black widow comes from their sexual cannibalism habit, which is when the female eats the male after mating.
Out of all the spiders, black widows are considered the most dangerous for humans – especially females, who are distinguishable by the red marks on their black body. If you’re ever bitten by a black widow, it’s important to seek medical attention immediately as the venom can have serious and even fatal effects if left untreated.
7. Black Mamba
The black mamba is a well-known snake, made famous by its appearance in the popular Kill Bill films.
It is considered to be the most venomous snake in Africa and inhabits trees in the savannas and dense forests south to the Sahara. The black mamba gets its name from the interior of its mouth, which is black.
6. Blue-ringed Octopus
The blue-ringed octopus is a small but deadly cephalopod. It’s rings are a warning to would-be predators that this creature is not to be messed with – their venom is lethal and there is no known antidote. Just one blue-ringed octopus has enough venom to kill 26 people, making it the most dangerous cephalopod on earth.
5. Golden Poison Frog
The golden poison frog (Phyllobates terribilis), also known as the golden dart frog, is the most poisonous amphibian on Earth. It secretes a poison that could kill up to 1,500 people.
The venom of this frog isn’t technically injected; instead, it’s secreted. In the past, indigenous people from Colombia would use the poison to wet the tips of their arrows and make them more deadly.
4. Dubois’ Sea Snake
Sea snakes, which are also called coral reef snakes, are a type of snake that can be found in the tropical waters of the Indian and Pacific Oceans. They’re actually one of the most wide-ranging reptiles in the world since they’re mostly found near land but can also swim upriver.
In terms of their appearance, they look a bit like eels since they’re long and thin. However, unlike eels, they don’t have gills so they need to come up for air to breathe.
Additionally, even though these snakes can be venomous, most bites won’t actually inject any venom into your system. But if you are injected with venom, you’ll start to experience symptoms like pain and paralysis at least half an hour later.
The stonefish is the most venomous fish in the world and it gets its name from its rock-like appearance. The spines on their fins can be deadly to humans and they can sting you whether you’re in the water or on the beach. They can survive on land for hours, so be careful where you step if you’re visiting the Indo-Pacific coast!
2. Inland Taipan Snake
The venom of the inland taipan, also known as Oxyuranus microlepidotus or small-scaled snake, is extremely dangerous. This deadly species can be found in Australia.
The inland taipan has enough venom to kill 100 adult humans and 250,000 mice. Its venom is between 200 and 400 times more toxic than most rattlesnakes. The neurotoxic action of the venom can kill an adult human in just 45 minutes, so it is essential to get to a medical facility immediately if you are bitten by this snake.
1. Sea Wasp
The sea wasp, or box jellyfish (Chironex fleckeri), contains enough venom to kill more than 50 people – making it the most venomous animal on the planet. This species is mainly found near Australia and New Guinea in areas with warm ocean waters.
As they age, sea wasps can grow tentacles up to 3 meters long. The older the sea wasp, the more lethal its venom becomes.
