Poisonous-Animal


 1. Box Jellyfish


The top prize for “The World Most Venomous Animal,” would go to the Box Jellyfish. It has caused at least 5,567 recorded deaths since 1954. Their venom is among the most deadly in the world. It’s toxins attack the heart, nervous system, and skin cells. And the worst part of it is that jelly box venom is so overpoweringly painful, that human victims go in shock, drown or die of heart failure before even reaching shore. Survivors experience pain weeks after the contact with box jellies.
You have virtually no chance to survive the venomous sting, unless treated immediately. After a sting, vinegar should be applied for a minimum of 30 seconds. Vinegar has acetic acid, which disables the box jelly’s nematocysts that have not yet discharged into the bloodstream (though it will not alleviate the pain). Wearing panty hose while swimming is also a good prevention measure since it can prevent jellies from being able to harm your legs.Jelly box can be found in the waters around Asia and Australia.

2. 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.

 

 

3. 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, don’t 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 is very small, only the size of a golf ball, but its venom is so powerful that can kill a human. Actually it carries enough poison to kill 26 adult humans within minutes, and there is no antidote. They are currently recognized as one of the world’s most venomous animals.
Its painless bite may seem harmless, but the deadly neurotoxins begin working immediately resulting in muscular weakness, numbness, followed by a cessation and breathing and ultimately death.
They can be found in tide pools in the Pacific Ocean, from Japan to Australia.

 

5. 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.

 

 

 

6. Stonefish

Maybe Stonefish would never win a beauty contest, but it would definitely win the top prize for being “The World Most Venomous Fish”. Its venom causes such a severe pain that the victims of its sting want the affected limb to be amputated. It is described as the worst pain known to man. It is accompanied with possible shock, paralysis, and tissue death. If not given medical attention within a couple of hours It can be fatal to humans.
Stonefish stores its toxins in gruesome-looking spines that are designed to hurt would-be predators.Stonefish mostly live above the tropic of Capricorn, often found in the shallow tropical marine waters of the Pacific and Indian oceans, ranging from the Red Sea to the Queensland Great Barrier Reef.

 

 

 

7. 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.

8. Inland Taipan



The prize for “The World’s Most Venomous Snake” goes to the Inland Taipan of Australia. Just a single bite from this snake contains enough venom to kill 100 human adults or an army of 250,000 mice. Its venom is at least 200 – 400 times more toxic than a common cobra. 
The Inland Taiwan’s extremely neurotoxic venom can kill an adult human in as little as 45 minutes. Fortunately this snake is very shy and there have been no documented human fatalities (all known bites were treated with antivenin).

 

9. Poison Dart Frog

 

If you ever happen to be running through the rain forests somewhere in Central or South America, do not ever pick up beautiful and colorful frogs – it can be the Poison Dart Frog. This frog is probably the most poisonous animal on earth.The 2 inch long (5cm) golden poison dart frog has enough venom to kill 10 adult humans or 20,000 mice. 

Only 2 micrograms of this lethal toxin (the amount that fits on the head of a pin) is capable of killing a human or other large mammal. They are called “dart frogs” because indigenous Amerindians’ use of their toxic secretions to poison the tips of their blow-darts. Poison dart frogs keep their poison in their skins and will sicken or kill anybody who touches or eats it.

 

 

10. Puffer Fish



Puffer Fish are the second most poisonous vertebrate on earth (the first one is golden dart Frog). The meat of some species is a delicacy in both Japan (as fugu) and Korea (as bok-uh) but the problem is that the skin and certain organs of many puffer fish are very poisonous to humans.
This puffy fish produce rapid and violent death..Puffer’s poisoning causes deadening of the tongue and lips, dizziness, vomiting, rapid heart rate, difficulty breathing, and muscle paralysis. Victims die from suffocation as diaphragm muscles are paralyzed. Most of the victims die after four to 24 hours. There is no known antidote, Most deaths from fugu happen when untrained people catch and prepare the fish.

Statistics show that there were 20 to 44 incidents of fugu poisoning per year between 1996 and 2006 in all of Japan and up to six incidents per year led to death. Since Fugu’s poison can cause near instantaneous death, only licensed chefs are allowed to prepare it.

Fruits & Vegetables


How to Use Fruits and Vegetables to Help Manage Your Weight




Fruits and vegetables are part of a well-balanced and healthy eating plan. There are many different ways to lose or maintain a healthy weight. Using more fruits and vegetables along with whole grains and lean meats, nuts, and beans is a safe and healthy one. Helping control your weight is not the only benefit of eating more fruits and vegetables. Diets rich in fruits and vegetables may reduce the risk of some types of cancer and other chronic diseases. Fruits and vegetables also provide essential vitamins and minerals, fiber, and other substances that are important for good health.



To lose weight, you must eat fewer calories than your body uses.
This doesn't necessarily mean that you have to eat less food. You can create lower-calorie versions of some of your favorite dishes by substituting low-calorie fruits and vegetables in place of higher-calorie ingredients. The water and fiber in fruits and vegetables will add volume to your dishes, so you can eat the same amount of food with fewer calories. Most fruits and vegetables are naturally low in fat and calories and are filling.
Here are some simple ways to cut calories and eat fruits and vegetables throughout your day:



 
Breakfast: Start the Day Right
Substitute some spinach, onions, or mushrooms for one of the eggs or half of the cheese in your morning omelet. The vegetables will add volume and flavor to the dish with fewer calories than the egg or cheese.
Cut back on the amount of cereal in your bowl to make room for some cut-up bananas, peaches, or strawberries. You can still eat a full bowl, but with fewer calories.





Lighten Up Your Lunch
Substitute vegetables such as lettuce, tomatoes, cucumbers, or onions for 2 ounces of the cheese and 2 ounces of the meat in your sandwich, wrap, or burrito. The new version will fill you up with fewer calories than the original.
Add a cup of chopped vegetables, such as broccoli, carrots, beans, or red peppers, in place of 2 ounces of the meat or 1 cup of noodles in your favorite broth-based soup. The vegetables will help fill you up, so you won't miss those extra calories.





Dinner
Add in 1 cup of chopped vegetables such as broccoli, tomatoes, squash, onions, or peppers, while removing 1 cup of the rice or pasta in your favorite dish. The dish with the vegetables will be just as satisfying but have fewer calories than the same amount of the original version.
Take a good look at your dinner plate. Vegetables, fruit, and whole grains should take up the largest portion of your plate. If they do not, replace some of the meat, cheese, white pasta, or rice with legumes, steamed broccoli, asparagus, greens, or another favorite vegetable. This will reduce the total calories in your meal without reducing the amount of food you eat. BUT remember to use a normal- or small-size plate — not a platter. The total number of calories that you eat counts, even if a good proportion of them come from fruits and vegetables.

 
Smart Snacks
Most healthy eating plans allow for one or two small snacks a day. Choosing most fruits and vegetables will allow you to eat a snack with only 100 calories.
About 100 Calories or Less
a medium-size apple (72 calories)
a medium-size banana (105 calories)
1 cup steamed green beans (44 calories)
1 cup blueberries (83 calories)
1 cup grapes (100 calories)
1 cup carrots (45 calories), broccoli (30 calories), or bell peppers (30 calories) with 2 tbsp. hummus (46 calories)
Instead of a high-calorie snack from a vending machine, bring some cut-up vegetables or fruit from home. One snack-sized bag of corn chips (1 ounce) has the same number of calories as a small apple, 1 cup of whole strawberries, AND 1 cup of carrots with 1/4 cup of low-calorie dip. Substitute one or two of these options for the chips, and you will have a satisfying snack with fewer calories.

Remember: Substitution is the key.
It's true that fruits and vegetables are lower in calories than many other foods, but they do contain some calories. If you start eating fruits and vegetables in addition to what you usually eat, you are adding calories and may gain weight. The key is substitution. Eat fruits and vegetables instead of some other higher-calorie food.
More Tips for Making Fruits and Vegetables Part of Your  Weight Management Plan

Eat fruits and vegetables the way nature provided—or with fat-free or low-fat cooking techniques.
Try steaming your vegetables, using low-calorie or low-fat dressings, and using herbs and spices to add flavor. Some cooking techniques, such as breading
and frying, or using high-fat dressings or sauces will greatly increase the calories and fat in the dish. And eat your fruit raw to enjoy its natural 
sweetness.


Canned or frozen fruits and vegetables are good options when fresh produce is not available.
However, be careful to choose those without added sugar, syrup, cream sauces, or other ingredients that will add calories. 

Choose whole fruit over fruit drinks and juices. Fruit juices have lost fiber from the fruit.
It is better to eat the whole fruit because it contains the added fiber that helps you feel full. One 6-ounce serving of orange juice has 85 calories, compared to just 65 calories in a medium orange.


Whole fruit gives you a bigger size snack than the same fruit dried—for the same number of calories.
A small box of raisins (1/4 cup) is about 100 calories. For the same number of calories, you can eat 1 cup of grapes.
