In the natural world, diversity is the most characteristic. There are species that look beautiful, splendid, gentle, friendly. There are also strange, mysterious, or aggressive nature. In addition, there are also beautiful, lovely but hidden creatures are scary " assassin kill people".
In this article I will introduce you to some species of beautiful appearance, but deadly poison.
At this time, box jellyfish (Cubozoa class) is the world's most venomous animal that humans have ever known. They live mainly in the Indian and Pacific Oceans. Each year, this scary animal has claimed the lives of hundreds of people.
These jellyfish have up to 15 m long tentacles and contain more than 5,000 microscopic needles on each tentacle, and you will die if you touch them. According to scientists, venom of this species directly affects the visual and cardiovascular system. As a result, its victims often die extremely rapidly.
The Octopus Green Ring lives primarily in the Pacific Ocean, from Japan's territorial waters to Australia. Look at the small body with a diameter of about 20cm and body color is extremely beautiful, few can imagine that this is one of the most dangerous species on the planet.
With only 25g of the Octopus Green Ring can paralyze the body of 10 adults and they have two types of powerful venom for hunting as well as defense. However, the scary point of this species is that their bites are not painful so it is very difficult for people to detect whether they are attacked or not. But, just a few minutes after being bitten, the victims will feel numb body, nausea, difficulty swallowing, difficulty breathing and eventually death if not treated promptly.
The Marbled Cone is the most distinctive species of the Conus genus, which lives primarily in the Indian Ocean. Only one drop of this species of venom is enough to kill 20 adults. When exposed, people immediately feel dizziness, shortness of breath, slow heart rate and death if not treated in time.
However, this species only uses venom to hunt and rarely cause death to humans. Because of that, the Marbled Cone snails are slow-bodied and can not bite us. However, if carelessly touching them, people will have to pay extremely expensive and sometimes even life.
Dart Frog is the common name for a group of frogs in the Dendrobatidae family, living in the tropical zones of Central and South America. Up until now, scientists have found 179 different species of non-poisonous frogs. Among them, the yellow duck frog is the most virulent species.
The dart frog's body contains an assortment of batrachotoxins. This is a toxin that directly affects the cardiovascular system and can block the activity of nerve cells to the muscle, causing paralysis and death. Even the poisonous frogs of a duck are yellow enough to kill 10 adults.
The Tetraodontidae are the second most scary vertebrae in the world, behind the Yellow Dart Frog. They live mainly in the waters of Japan, China, the Philippines and Mexico.
In the liver, kidney and sometimes puffer skin, there is a strong neurotoxin called tetrodotoxin. Even so, the puffer fish's venom is 1,200 times more dangerous than cyanide, and only one toxin can kill 30 adults.
