One of the reasons a species exists is its ability to take out its prey. Nature gives a species certain capabilities or superpowers that help them survive to further their existence. Some creatures have powers that are much more dangerous and deadly than others. A species doesn’t have to look harmful to be so. Many appear cute and unique rather than deadly.
The Great White Shark

Sharks have gotten a lot more attention over the past decade as they come into contact with humans more frequently. Great white sharks can swim at miles of up to 37 mph. They are also giant, spanning over twenty feet long sometimes, which means that they can out-power almost any prey.
The Giant Pacific Octopus

A Giant Pacific Octopus is named such because they can span up to sixteen feet and weigh as much as 110 pounds. They are camouflaged, which means they blend into their marine surroundings. So not only do they have the advantage of not being seen, but when they attack, it is usually a certain death for their prey.
The Asian Giant Hornet

The Asian Giant Hornet is indigenous to Asia, and its sting is tantamount to a nail gunshot. Often referred to as “murder hornets,” they are slowly becoming a problem in North America, first landing here in 2020.
The Hippopotamus

The Hippopotamus might look cute, but they are one of the most dangerous species on the planet. They don’t attack people for food, but they will protect their territory from any other species that invade it.
The Saw-Scaled Viper

Although small, the Saw-Scaled Viper is mighty. It is a highly aggressive snake species whose victims have about ten hours to find an antivenom before their entire body shuts down and they die of internal bleeding.
The Puffer Fish

One of the world’s oddest species is also one of the most dangerous. The Puffer Fish will “puff” up and become extremely large for unsuspecting predators. They are also covered in tetrodotoxin, which is highly toxic to prey and predators alike.
The Assassin Bug

With a name like the “assassin” bug, you can guess that it is known to be dangerous. Also called the kissing bug, they are known to bite humans on the lips, where they deliver toxins that are often enough to be fatal.
The Piranha

Many movies have showcased piranhas because of how dangerous they are. Piranhas are from South America and have inhabited the waters there for over a million years. There are several different types of piranhas, but they all share one common trait, and that is that they can eat their prey alive. The red-bellied and black varieties are known as the most deadly.
The Stonefish

Stonefish camouflage to rocks, so they are hard to spot. They are considered one of the most dangerous fish species in the world. If they are threatened, they can shoot 13 spines at one time to defend against that threat, often killing their prey.
The Water Monitor

The Water Monitor can live both on land and underground. They smell their prey and predators using their tongues and can pretty much do anything to catch their food, including climbing, swimming, and running.
The Tarsier

The Tarsier is a very odd-looking creature with bug eyes that resembles a Teddy Bear, but there is nothing cuddly about them. They are one of the most deadly species on the planet due to their deadly bite.
The King Cobra

The King Cobra can lengthen up to 18 feet, and they can soar their bodies as many as six feet off of the ground. Known as the longest venomous snake on the planet, their bite can be dangerous at best and deadly at worst.
The African Elephant

The size of the African Elephant makes it an inherently dangerous species. Unlike some other dangerous species, the young elephants are just as dangerous as the older ones. A full-grown elephant can weigh upwards of 12 thousand pounds.
The Portuguese Man O’ War

A Portuguese Man O’ War is a siphonophore creature, meaning that it is made of many different colonies that work together for their survival. Their tentacles can grow lengths of up to 165 feet, and their sting is venomous and can be fatal.
The Africanized Honey Bee

When someone talks about “killer bees,” they are speaking of the Africanized Honey Bee. It is a type of bee species that is dangerous and can be fatal, hence the nickname.
The Cone Snail

One of the most beautiful and deadly creatures on earth is the Cone Snail. Under the protection of the shell is a tongue that can inject over 100 different toxins instantly.
The Poison Dart Frog

Frogs are cute and little, but that doesn’t mean that they can’t be dangerous. The Poison Dart Frog is one of the most poisonous creatures on the planet and is highly toxic to the skin through touch.
The Blue-Ringed Octopus

Although very cute and unique looking, the Blue-Ringed Octopus has a very dangerous venom that can penetrate your skin underwater. In just five minutes, the affected area will be numb, and you can have speech difficulties and even experience full paralysis.
The Flower Urchin

The Flower Urchin is the most dangerous species of the sea urchin variety. The creature is filled with two different kinds of venom. One of them causes muscle spasms, and the other leads to anaphylactic shock and convulsions. The two combined can be fatal.
The Indian Taipan

Snakes are both scary-looking and can be scary. The Indian Taipan has one of the most venomous bites of any reptile in existence. Just one bite can kill as many as 250 thousand mice and up to 100 adults. That is a lot of overkill.
The Black Mamba

Venomous snakes are some of the most poisonous creatures on the planet. The black mamba is especially dangerous and is named for the black color that aligns their mouths. They are not only incredibly fast, traveling at up to 12.5 mph, but one sting of their venom can be deadly.
The Deathstalker

Their name says it all. The deathstalker is a scorpion that has venom that is so potent that it causes paralysis in their prey. The sting also leads to fever, unbreakable pain, and, in some instances, death. Hence, why they have the word death in their name.
The Gorilla

Although gorillas are close to human beings, their strength far exceeds any human’s strength. When they attack, they go at it full throttle and will do so if they feel any threat at all. They typically show warning signs of thumping their chests, grunting, and scratching, but it is best not to approach them to begin with.
The Brazilian Wandering Spider

Spiders are usually small and sneaky, but they are also very dangerous. Anyone who gets bitten by the Brazilian Wandering Spider will experience a racing heart, excessive sweating, extremely low or high blood pressure, vertigo, and blurred vision. The worst part is you can’t even see them coming.
The Sidewinder

Much like the other snakes on this list, the Sidewinder is a very dangerous species. It is named such due to the unusual way that it can move sideways across the sand. They are found in both South and North America, and they ambush their prey if it gets too close to the nest with a venomously deadly bite.
Species all have powers that allow them to survive. Some are more dangerous to their prey and predators than others. Just because a species might appear harmless, that doesn’t make it so. If you see any of these creatures, proceed with caution and get away as quickly as you can.
