Top 10 Sea Creatures More Dangerous Than Sharks

When talking about dangerous animals, sharks have a really bad reputation. Most people are afraid of sharks just because they hear these stories about them. Sharks in reality don’t usually attack humans since we aren’t a part of their diet. There’s far more dangerous sea creatures we should actually worry about.
The Top Ten
1 Box Jellyfish Box jellyfish are cnidarian invertebrates distinguished by their cube-shaped medusae. Some species of box jellyfish produce extremely potent venom: Chironex fleckeri, Carukia barnesi and Malo kingi.

These guys might not have teeth but that doesn't stop them from being deadly in their own right. They can swim better than most jellyfish which suggests they may actually hunt their prey. Oh and One box jellyfish contains enough venom to kill up to 60 people, and what makes them even more dangerous is their venom's speed of acting. The sting of a box jellyfish can kill you in less than five minutes. They are usually found off the coast of Australia or Southeast Asia

It's the most dangerous jellyfish ever discovered. This is the cobra of the sea.

2 Blue Ringed Octopus The Blue Ringed Octopuses (Hapalochlaena) are the four strongly venomous species that are found on the coral reefs and tidal pools in the Pacific and Indian Ocean, particularly from Australia to Japan. It is known as one of the most poisonous and deadliest sea creatures. It can kill a human body by injecting a toxin from its saliva by biting a victim.

One of the deadliest molluscs ever. It's venom can cause cardiac arrest.

3 Stonefish Synanceia is a genus of fish of the family Synanceiidae, the stonefishes, whose members are venomous, dangerous, and even fatal to humans. It is one of the most venomous fish known. They are found in the coastal regions of the Indo-Pacific.

The Stonefish is quite good at camouflage so they can be hard to see. Despite being about 30-40 centimeters long these guys pack a strong punch. The venom of a stonefish can cause excruciating pain, temporary paralysis and even heart failure. They are one of the most venomous fish in the entire world

4 Flower Urchin

The Flower Urchin is not to be messed with. It's in the Guinness Book of Records as the world's "most dangerous sea urchin" these urchins have powerful stings that can cause severe pain

5 Stingray

Stingrays are no joke. One actually killed Steve Irwin famous Crocodile hunter. They only attack if you happen to step on them since they tend to be bottom feeders

That's why it called stingray. It have stings.

6 Cone Snail

Cone Snails may appear innocent but a single drop of venom could kill 20 people. They can be in the Indian-Pacific Ocean as well as in the Atlantic off the coast of Florida. If you are a shell collector I'd stay away from these guys

7 Sea Snake

There are about 30-50 Sea Snake species often found in the Indian Or Pacific Ocean. They usually aren't aggressive but they pack a potent venomous punch. If you thought land snakes were scary these sea snakes are on an entirely different playing field. They have to have stronger venom to instantly kill their prey. Some of the less venomous ones can be more aggressive however. The Dubois and Beaked Sea Snakes are two of the more notable ones

8 Saltwater Crocodile The saltwater crocodile, also known as the estuarine crocodile, Indo-Pacific crocodile, marine crocodile, sea crocodile or informally as saltie, is the largest of all living reptiles, as well as the largest riparian predator in the world.

Saltwater crocodiles are the largest species of Crocodiles on the planet. And with their size they have power. The saltwater crocodile has the most powerful bite in the world, its jaw has up to 10 times more strength than the great white shark's. Unlike other predators saltwater crocs are murderous on both land and sea.

9 Surgeonfish

They look pretty but they have sharp spines that can be venomous and cause deep gashes. They aren't aggressive usually but still a good idea to stay away from them

10 Lionfish

These fish look pretty but don't let it fool you. They have spines that won't necessarily kill you but they are extremely painful. Fortunately they use their spines only in defense and won't attack you unless provoked. They are found generally in the Caribbean or East Atlantic Ocean

The Contenders
11 Pufferfish The Tetraodontidae are a family of primarily marine and estuarine fish of the order Tetraodontiformes.

Pufferfish are dangerous not just because of their spikes. Just because of the venome exist.
