4 Most Poisonous Animal in the World & 4 Most Poisonous Animal in the World Pics

Box Jellyfish
It is really hard to tell which animal is the most poisonous in the world. The one that has the most toxic chemicals? The one that kills the biggest amount of people a year? Or maybe the one with the biggest amount of poison?
First of all, I have to admit that the title is a bit incorrect, because there is a difference between poisonous and venomous animals. A poisonous animal carries harmful chemicals called toxins primarily used for self defense. Therefore venomous animals deliver their toxins by stinging, stabbing, or biting. So poisonous animals are passive killers, while venomous animals are active killers.
Nevertheless, theory aside, they are all really dangerous. So look really closely at each photo, cause next time you meet them can be the last thing you ever see.
1. Box Jellyfish : If the yardstick for measuring the deadliest of the worlds mot poisonous creatures is assumed to be the number of deaths that have been caused by them, then the Box Jellyfish definitely tops our list of worlds most poisonous creatures. This creature, which is just about the size of a palm, has reportedly caused deaths to almost 6000 people till date. This number is the highest recorded number in the world. This blue colored jellyfish has one of the most powerful, tantalizing and venomous stings in the world and it is found around the coastlines of South East Asia and Australia.

Poison Dart Frog
The poison dart frog is another creature you might find cute if you found it in the wild but just touching this little guy can put you in harms way. Native to South and Central America, the frog got its name because indigenous tribes used to use the poison as an addition to their blow darts.
10. Puffer Fish : The puffer fish is a delicacy in many part of Japan and China, but some organs of the fish are deadly to the human beings- making it one of the worlds most poisonous and lethal animals. The poison of the fish is devastating for the one who consumes it and results in deadening of the muscles, increasing of the heart rate, dizziness, vomiting and permanent seizure within minutes of consuming the deadly poison.
 The stonefish is the worlds most poisonous fish, and probably the ugliest also. It is often remarked that when a stone fish attack a human being, the pain is so severe that the person wants to amputate the area affected. Its bit may not be lethal and can be treated within hours, but if left untreated for more than 2-3 hours, a bit from the stone fish can result into death for the human beings.
Marbled Cone Snail
This little beautiful looking Marbled Cone snail can be as deadly as any other animal on this list. One drop of its venom is so powerful that it can kill more than 20 humans. If you ever happen to be in warm salt water environment (where these snails are often found) and see it, dont even think of picking it up. Of course, the true purpose of its venom is to catch its prey.
Symptoms of a cone snail sting can start immediately or can be delayed in onset for days. It results in intense pain, swelling, numbness and tingling. Severe cases involve muscle paralysis, vision changes and breathing failure. There is no antivenom. However, only about 30 human deaths have been recorded from cone snail envenomation.
4. Blue-Ringed Octopus : The blue ringed Octopus was considered one of the worlds most poisonous sea creatures till some time back, until the Box Jellyfish took over. Nevertheless, this creature is till capable of killing up to 25 humans in one bite. Found in the Pacific pools from Japan to Australia, this creature’s bite is impalpable in most cases, but the venom starts working immediately on the muscles and heart- causing weakness, seizure and death within minutes.

King Cobra
The King Cobra (Ophiophagus hannah) is the world’s longest venomous snake - growing up to 5.6 m (18.5 ft) in length. Ophiophagus, literally means “snake-eater” as it eats other snakes. One single bite of this deadly snake can easily kill a human. This snake is even capable of killing a full-grown Asian Elephant within 3 hours if the larger animal is bitten in a vulnerable area such as the trunk.
It’s venom is not as toxic as other venomous snakes, but King Cobra is capable of injecting 5 times more venom than black mamba and can result in mortality up to 5 times faster than that of the black mamba. It is quite widespread, ranging across South and South-east Asia, living in dense highland forests.
 The Brazilian wandering spider :
The Brazilian Wandering Spider (Phoneutria) or banana spider appears in the Guinness Book of World Records 2007 for the most venomous spider and is the spider responsible for most human deaths.
This spider is believed to have the most potent neurotoxic venom of any living spider. Only 0.006mg (0.00000021oz) is sufficient to kill a mouse. They are also so dangerous because of their wandering nature. They often hide during daytime in highly populated areas inside houses, clothes, boots, and cars.
Its venomous bite causes not only intense pain, the venom of the spider can also cause priapism – uncomfortable erections lasting for many hours that lead to impotence.
Blue-Ringed Octopus
 The blue ringed Octopus was considered one of the worlds most poisonous sea creatures till some time back, until the Box Jellyfish took over. Nevertheless, this creature is till capable of killing up to 25 humans in one bite. Found in the Pacific pools from Japan to Australia, this creature’s bite is impalpable in most cases, but the venom starts working immediately on the muscles and heart- causing weakness, seizure and death within minutes.
Death Stalker Scorpion
Contrarily to the popular belief most of the scorpions are relatively harmless to humans as stings produce only local effects (pain, numbness or swelling). However, the Death Starker Scorpion is highly dangerous species because its venom is a powerful cocktail of neurotoxins which causes an intense and unbearable pain, then fever, followed by coma, convulsions, paralysis and death. Fortunately, while a sting from this scorpion is extremely painful, it would be unlikely to kill a healthy, adult human. Young children, the old, or infirm (with a heart condition) are at the biggest risk.
Death stalker scorpions are spread in North Africa and Middle East.
Inland Taipan
The inland Taipan is recognized as being the worlds most poisonous snake, having the capability to kill over a hundred human beings within 45 seconds from a single bite. Found in Australia, the Inland Taipan is definitely the one to beware of.

Mosquito Dengue Fever

Dengue fever (UK: /ˈdɛŋɡeɪ/, US: /ˈdɛŋɡiː/), also known as breakbone fever, is an infectious tropical disease caused by the dengue virus. Symptoms include fever, headache, muscle and joint pains, and a characteristic morbilliform skin rash. The virus has four different types; infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type is believed to increase the risk of severe complications. The incidence of dengue fever has increased dramatically since the 1960s, with around 50–100 million people infected yearly. Others have more severe illness (5%), and in a small proportion it is life-threatening.[1][3] The incubation period (time between exposure and onset of symptoms) ranges from 3–14 days, but most often it is 4–7 days.[4] Therefore, travelers returning from endemic areas are unlikely to have dengue if fever or other symptoms start more than 14 days after arriving home. The dendritic cell moves to the nearest lymph node. Meanwhile, the virus genome is replicated in membrane-bound vesicles on the cell's endoplasmic reticulum, where the cell's protein synthesis apparatus produces new viral proteins, and the viral RNA is copied. Immature virus particles are transported to the Golgi apparatus, the part of the cell where the some of the proteins receive necessary sugar chains (glycoproteins).

However, early disease can be difficult to differentiate from other viral infections.[5] A probable diagnosis is based on the findings of fever plus two of the following: nausea and vomiting, rash, generalized pains, low white blood cell count, positive tourniquet test, or any warning sign (see table) in someone who lives in an endemic area. Warning signs typically occur before the onset of severe dengue.[8] The tourniquet test, which is particularly useful in settings where no laboratory investigations are readily available, involves the application of a blood pressure cuff for five minutes, followed by the counting of any petechial hemorrhages; a higher number makes a diagnosis of dengue more likely.[8] It may be difficult to distinguish dengue fever and chikungunya, a similar viral infection that shares many symptoms and occurs in similar parts of the world to dengue.


Mosquito Eggs Larva And Some Infi

To determine the sex of a mosquito, look at the antenna. If the antenna are "plumose" (hairy), the mosquito is male. If the antenna are "pilose" (not very hairy), the mosquito is female (see diagram above)
2. To determine the genera of medically important mosquitoes, look at the palps (sensory organs just lateral to the proboscis, the stick-like organ that punctures the skin for blood meal). If it is a female mosquito with long palps, the mosquito is Anopheles. Anopheles mosquitoes rest and bite with their bottoms up (approximately 45 degree angle to the skin). If you see a mosquito biting you with it's bottom parallel to the skin, it is not likely a anopheles, and you can rest assured that you won't get malaria from that bite (although you could get Yellow Fever, Dengue, Fillariasis, West Nile virus, or another mosquito-borne arthropod virus. Adult females lay their eggs in standing water, which can be a salt-marsh, a lake, a puddle, a natural reservoir on a plant, or an artificial water container such as a plastic bucket. The first three stages are aquatic and last 5–14 days, depending on the species and the ambient temperature; eggs hatch to become larvae, then pupae. The adult mosquito emerges from the pupa as it floats at the water surface. Adults live for 4–8 weeks. The larvae spend most of their time feeding on algae, bacteria, and other micro-organisms in the surface microlayer. They dive below the surface only when disturbed. Larvae swim either through propulsion with the mouth brushes, or by jerky movements of the entire body, giving them the common name of "wigglers" or "wrigglers". A similar cycle of activity occurs in the posterior midgut and posterior midgut lumen, whereas aminopeptidase in the posterior midgut epithelium decreases in activity during digestion. Aminopeptidase in the anterior midgut is maintained at a constant low level, showing no significant variation with time after feeding. alpha-glucosidase is active in anterior and posterior midguts before and at all times after feeding. In whole midgut homogenates, alpha-glucosidase activity increases slowly up to 18 hours after the blood meal, then rises rapidly to a maximum at 30 hours after the blood meal, whereas the subsequent decline in activity is less predictable. All posterior midgut activity is restricted to the posterior midgut lumen. Depending upon the time after feeding, greater than 25% of the total midgut activity of alpha-glucosidase is located in the anterior midgut.
