Scaw-Scaled Viper

The venom of this viper contains toxins that cause the body to develop bleeding disorders, which can lead to its victim dying from internal hemorrhaging. In other words, you’d better run when you see it!

Sarcastic Fringehead

This fish is proof that size doesn’t matter. Even though it’s small, it’s fearless and aggressive to the point it’s earned the respect of fisherman from all over. They’re extremely territorial, so they’ll attack any animal that comes near their home. They have a huge mouth span that contains tons of sharp teeth that they use to wrestle other fish for territory.

Thick-Tailed Scorpion

Like the cobra, this scorpion can eject its venom as far as one meter away. Even though it’s not usually deadly, its venom causes extreme pain and temporary blindness, that if left untreated will become permanent. This guy likes to hang out in the dry areas of many countries in Africa.

Psychedelic Octopus

The blue-ringed octopus looks like it stepped out of a psychedelic dream, but its true nature is a lot more dangerous. It uses a powerful neurotoxin that paralyzes the respiratory muscles of its prey. If someone gets stung, they would need to seek immediate medical attention or suffer from death by asphyxiation.

Frilled Shark

Frilled sharks may look like eels, but their fierceness and hunting ability makes them as dangerous as their shark cousins. This animal has dozens of trident-shaped teeth, that face backwards, which are used to hook its prey and keep it from escaping. They tend to live in very deep waters, which is great news because you wouldn’t want to encounter one of these.

Siphonophore

Even though this creature looks like a jellyfish, it’s actually a siphonophore. What’s scary about this animal is its venom. It leaves enormous, red welts on the skin, which travel to the lymph nodes causing fever, shock, and other allergic reactions. It can take the title of having one of the deadliest venoms in the world.

Strange-looking Seal

Due to the fact that they have an inflatable bladder on their heads, adult male hooded seals are quite strange looking. These animals are pretty antisocial and territorial, which separates them from other types of seals. They’re also known to be aggressive towards humans. They live in the Arctic Sea around Canada, Greenland, and Iceland.

Bullet Ant

This small creature’s name is pretty fitting. People say the pain from this insect’s venom is so powerful, it feels like you’re being shot. The venom contains a toxin that targets the central nervous system, which causes paralysis that is strong enough to take down a full grown man.

Poisonous Dart Frog

Even though this bright yellow amphibian looks cute and kid-friendly, it is certainly not. This dangerous frog is about the size of a paperclip, but holds enough poison to kill ten men. The Golden Poison Dart Frog is considered the most poisonous animal in existence.

Komodo Dragon

The komodo dragon is the largest species of monitor lizard in the entire world. It’s bite can cause hemorrhaging, low blood pressure, hypothermia, and muscle paralysis. Whether it’s caused by bacteria or certain venomous proteins in the dragons saliva, scientists can’t be certain why it happens.
