Under the deep blue water there are countless dangerous creatures, from enormous creatures with tremendous power to tiny creatures with powerful self-defense weapons. Here are 10 of the most dangerous creatures of the ocean posted in scientific journal Livescience.

Sea eel

There is a snake-like body, mouth protruding and jaws wide. This primitive creature really looks like Death. Be aware, it is a fish and it can be nearly 2.5m long.

According to the National Oceanic and Atmospheric Administration (NOAA), a sharp tooth bite and powerful jaw from the eel species will create a scabbing wound that can cause infection by bacteria from the mouth of this fish.

Eels often hide in crevices or rock holes throughout the day, they hunt at night. They eat any fish or other creatures that can be caught.

Some experts at NOAA have given advice to avoid being bitten by this fish, that is, do not put your hands in the rocks or sea caverns and never feed them.

Sea lion

Sea lions are smart, trainable and great attraction in circuses, but sometimes they can bite humans, as this is extremely territorial.

In California, an increase in sea lion attacks was reported at Manhattan, Newport beaches and in San Francisco in 2006, which became a concern for scientists. Some researchers suspect that sea lions may have eaten poisoned fish, leading to aggressive action.

The city of San Diego posted a warning on its website saying: 'Like all other wildlife, the characteristics of sea lions and seals are not predictable. They have sharp teeth and can bite, especially when they are stressed or cornered. '

Stingray

The death of Steve Irwin, the host of 'Crocodile Hunter' and one of the world-renowned wildlife activists in 2006, was caused by the stingray. . This incident caused the brother of this shark to be known as the most dangerous and aggressive species.

This fish's 20cm long tail is like a jagged tongue. They become hard, sharp when rays feel danger, in addition to saw teeth like a stingray knife also contain venom that can kill other predators.

According to the Mote Marine laboratory in Sarasota, Florida, USA: 'The venom of stingrays is a large protein-based toxin that can create terrible pain for mammals and may also alter the frequency of heart beats and respiration. " Fortunately, stingrays rarely choose humanity as an attack target.

Crocodile

Saltwater crocodiles have confirmed their position as one of the most fierce animals in the wild world.

They can grow to over 6m long and weigh more than a ton. They are known as fierce predators for many animals including monkeys, kangaroo, bison, buffalo and even sharks.

Completely based on the body, alligators can drag down large water buffalo. Using the "death roll" attack method, the crocodiles kill their prey by grabbing its jaws into the prey's body and then spinning around to break the bad guys' joints. This technique is also used to fight other large animals.

Lion fish

Popular in family aquariums, lion fish exhibits a set of nanotubes which are very colorful.

According to NOAA, although not dangerous to human life, the poisonous thorns of this fish also create painful burns that can lead to headaches, vomiting and shortness of breath.

The worst condition of a wound usually lasts only about an hour, but there are also cases of pain and itching that lasts for a week.

Inside the aquarium fish, lion fish are very gentle and in the natural environment they are really an assassin. This fish has a good fertility and aggressive nature, its food is smaller fish. In many places they have surpassed many other marine species.

Sea snake

The innate fear of humans about snakes has pushed the animals into the water into the list. However, the reality is that sea snakes are just copies of poisonous snakes on the ground.

Puffer fish

Puffer fish is the cause of many human deaths, all of which are poisoned when eaten. The poison of puffer fish is tetrodotoxin (a type of neurotoxin with the formula C ₁₁ H ₁₇ N ₃ O ₃ ) even stronger than cyanide.

Puffer fish toxin is a bioactive substance studied in many countries around the world, especially Japan, Korea and China. They are used primarily in medicine, especially a drug made from the poison of the puffer fish that has been tested to treat symptoms in drug detoxification.

Rock fish

This fish ranks third in the list of dangerous fish for two reasons: it is one of the underwater creatures that releases the strongest venom, and it is also the master of camouflage art. This fish often hides in reefs or among coral reefs that look like a real stone.

Rock fish don't attack, but humans need to avoid stepping on it. Its prickly thorns are often used to defend against attacks by sharks or other predators. Its venom shock or temporary paralysis, but can also lead to death if not treated promptly.

Shark

Definitely not to ignore the white shark, the great predator of the ocean when talking about dangerous animals in the ocean. Although, in fact, sharks are killed more than humans are eaten by sharks, but this is still the species that causes natural fear for humans.

Sharks eat everything: fish, seals, birds, squid, shark, dolphin . even things floating on the sea like old tires. They can be 5.5m long and weigh tons.

Sharks are found in many temperate and tropical seas, which are common around the central Pacific islands. The white shark is considered the most aggressive and aggressive species in shark family.

Jellyfish box

According to the US National Science Foundation, about 20 to 40 people die from boxed jellyfish every year in the Philippines and they have declared 'the disaster from box jellyfish can be considered serious'.

An Australian box jellyfish may have dozens of tentacles, each over 4.5 meters long, with toxins that can kill 60 people.
