The Most Dangerous Five Animals In The World

No comments
Poison Dart Frog

This unique type of frogs live in Central and South America, And belongs to the family Dendrobatidae. Frog size varies from 1.5 cm to 6 cm. Their skin is very attractive and colorful, but also toxic. They contain a toxic substance alkaline greasy. They attract their prey using their bodies colorful cleverly. Remnants of poison frog contains enough poison to kill 10 people in a single moment. However, there are some animals that have immune and safe from toxins. There are approximately 100 species of poison dart frogs all over the world and which can be found in various locations such as Colombia and Brazil.

Saltwater Crocodile

They are one of the oldest reptiles that can be found in Asia, Africa and Australia, and they live in the rivers and lakes of salt water. That is why they are called saltwater crocodile. Size of 5 to 20 feet. This is one of the most dangerous animals on the planet. Crocodiles famous for deceit and deception. They get rid of their prey silently with their Jas. They are strong and very fast, they can pressed bones, and use them as a weapon in the attack. The estimated number of victims of the saltwater crocodile from 600 – 800 per year.

Piranha Fish 300x242

Piranha Fish

Piranha fish belongs to the family Characidae. It is an omnivorous freshwater fish which is a resident of rivers in South Africa. They have Sharp teeth to help in achieve its desire in meat. Piranha red-rumen is the most dangerous. They are able to identify the human body through the twinkling of an eye. Also gravitate towards blood just like her colleague white shark. According to recent research, attacks on humans are not very frequent. However, it is very dangerous fish and came in third place in the list of the most dangerous animals.

African Lion 300x241

African Lion

King of the Jungle won fourth place in the list of the most dangerous animals. This animal belongs to the Felidae family of big cats. African lion is very lazy and gets 20 hours of rest per day. He is one of the largest cats. They live in sub-Saharan Africa and some parts of Asia. They have a terrible speed, claws, razor sharp teeth to attack prey and they cause 800 deaths annually.

White Shark

One of the huge animals that live beneath the surface of the sea and belongs to the family of the shark. Has a sense of the feeling of blood beneath the surface of the water and is what constitutes a shield for him at the side of his deadly teeth. The smell of blood makes them excited and in the rampage case, they eat everything that comes their way. White Shark Never attack a man for revenge as the Movies always claim, but it is very dangerous though, when it is excited. About 100 of the deaths caused by white shark attacks annually.

Plants Can Kill Too! Some Plants Save lives while Others are Deadly!

rosary pea imageRosary Pea The most dangerous plants on earth

The rosary pea  may sound sweet and downright pious, but it’s actually one of the most dangerous plants on earth. Its seeds contain a particular lectin known as abrin; if chewed and swallowed, death will follow shortly. The seeds are easily identified with their distinctive bright red jacket and single black dot (almost like a reverse Black Widow spider). Abrin, which does its damage by inactivating ribosomes, is one of the most fatal toxins on earth. After the  vomiting, fever, nausea, drooling and G.I. dysfunction but before the bizarre hyperexcitability, edema and fatally convulsive seizures, renal tubular degeneration, bladder and retinal hemorrhage and widespread internal lesions typically develop.

monks hood photoMonkshood

The nickname for monkshood is actually “wolfsbane”. That’s owing to its once common use by farmers as a very effective wolf extermination tool. (Not to be left out, fowl are also fatally affected by the related hensbane.) The monkshood has the distinction of evidently being the bane of many creatures: its nicknames include womensbane and leopard’s bane, though it is also known as blue rocket and devil’s helmet. It is technically part of the aconitum  genus, of which there are more than 250 species. The wolfsbane used to be a popular werewolf detection tool, by the way. (Status was determined by holding the flower near the alleged’s chin; a yellow-tinged shadow on the skin was thought to be confirmation.)

bush mans poison photoBushman’s poison

The aptly-named Bushman’s poison  has famously been used by the Khoisan of South Africa to poison the tips of their arrows. Though the plant produces pleasantly scented flowers and a tasty plum-like berry, the milky sap can be fatal. The leaves, however, have medicinal properties. Bushman’s poison is also known as the winter sweet.

angels trumpetAngel’s trumpet

What could be sweeter than the sound of an angel’s trumpet? Perhaps the moaning agony of a trip that won’t end. Related to petunias, tomatoes and potatoes, the angel’s trumpet (datura stramonium) is a highly effective hallucinogen, but should not be consumed for recreational purposes as it can also be lethal. According to wikipedia: “The active ingredients are atropine, hyoscyamine and scopolamine which are classified as deliriants, or anticholinergics. Due to the elevated risk of overdose  in uninformed users, many hospitalizations, and some deaths, are reported from recreational use.” This common plant also goes by many other names, including jimson weed, stink weed, loco weed, and devil’s snare. One 18-year-old who was house-sitting alone for his uncle recounts how he decided to prepare some angel’s trumpet tea  in curiosity and almost died (a friend burst in on him convulsing on the bathroom floor and the authorities assumed he was on an acid trip).

water hemlock infosWater Hemlock

The poison hemlock famously drunk by Socrates is deadly, but the water hemlock is just as fatal. According to the USDA, water hemlock or poison parsnip is “the most violently toxic plant in North America”. The flowers and stems are safe, but the stalky roots contain chambers that are full of a deadly sap containing the convulsant cicutoxin. Grand mal seizures are followed by a quick death if even a tiny amount is consumed.

Nightshade

Also known as the devil’s cherry, black cherry, great morel and belladonna, the nightshade  is toxic from tip to top. Containing atropine, a deadly alkaloid, those who ingest even a small amount of the plant will soon notice they have lost their voice. Respiratory trouble and convulsions follow. The plant is problematic because its cherries are so sweet and children are frequently attracted to the wild fruit. Strangely, horses, birds, sheep, goats and pigs seem to be immune to the effects of nightshade. Nightshade poisoning is treatable with an emetic if treatment is sought swiftly. Plutarch spoke of armies being wiped out by nightshade, and legend has it that Macbeth’s soldiers poisoned the invading Danes with wine made from the sweet fruit.

rhododendron imageRhododendron

The toxic rhododendron, a stalky tree-like evergreen shrub with large, brilliant blooms, is famously seen throughout much of the Pacific Northwest and is the state flower of Washington. Its relative, the popular garden shrub azalea, is also poisonous. Both plants contain andromedatoxin, which can cause severe pain, lethargy, depression, vomiting and nausea, progressive paralysis, coma and eventual death. All parts are deadly.

oleander imageOleander

The oleander is the most deadly plant in the world. It is also tremendously popular as a decorative shrub. Just one leaf can kill an adult, and fatal poisonings have resulted from minimal exposure to the twigs, blooms and berries. The plant contains numerous toxins, including nerioside, oleandroside, saponins, and cardiac glycosides. Though native to parts of the Mediterranean and Asia, it is now widely cultivated throughout the world. Fatalities among horses and other livestock are common. Once ingested, oleander goes to work simultaneously on the nervous system, the cardiovascular system, and the digestive tract.

moon seedsMoonseed

A otherworldly name and a plant with often fatal effects. The seeds of this Eastern North American drupe (stone fruit) are extremely toxic to humans, although birds can eat them. Moonseeds first cause paralysis but are fatal in larger doses and/or if treatment is not sought immediately.

daphne spurge laurel imageDaphne

This plant, also called the spurge laurel, is a favorite ornamental shrub in Europe. This drupe-producing evergreen with waxy, attractive foliage and gorgeously fragrant blooms is also highly toxic. Consumption of the leaves or red or yellow fruits will first cause nausea and violent vomiting, followed by internal bleeding, coma and death. The daphne plant is rich in the toxin mezerein.

castor plantsCastor Bean

Castor oil – for anyone unlucky enough to have been force spoon-fed this healthy yet disgusting fluid as a child, you may be surprised to learn that an ingredient in the castor bean  just happens to be the deadliest plant poison on earth. Literally. Just one tiny castor bean is enough to kill an adult within a few minutes. Castor oil is made safe (but not palatable) with the removable of the lethal compound known as ricin. Amazingly, castor bean plants are grown for decorative purpose all over the place, particularly in California.

You don’t wanna mess with plants, do you?

A New Theory About Bird’s System For Navigation

No comments

birds migrationBirds migration is the journey that birds travel due to the absence of food or the change in weather, in order to travel to their own habitats. It is known that some birds use the sun as a compass in their navigation’s, others depend for their migration on detecting magnetic fields.

Scientists of University of Oxford along with the scientists of National University of Singapore has reached to a new theory that the birds can see the force of magnetism, that are invisible for us. The concept is that when the birds eye absorb the light photon, a molecule in the eye kick an electron for a distance of few nanometers. While the electron return to its place it creates an electric dipole field which increases the bird’s sight.

That’s the kind of evolutionary trick that’s truly amazing. As worded in an Oxford press release: “According to the new model, when a photon of light from the Sun is absorbed by a special molecule in the bird’s eye, it can cause an electron to be kicked from its normal state into an alternative location a few nanometres away. Until the electron eventually relaxes back, it creates an ‘electric dipole field’ which can augment the bird’s vision – for example altering colours or brightness.”
There are many of these molecules with many orientations spread throughout the eye, the researchers presume, so as the bird moves its head the patterns in its field of vision shift, offering crucial information about the Earth’s magnetic field and navigational direction.
The researchers also note that while this sounds like some kind of higher vision mechanism, it’s really the kind of thing that could evolve quite easily. It doesn’t require the development of some new sensory organ but rather just piggybacks on normal vision. If some birds developed this trait via genetic mutation or some other avenue, it would give them a distinct evolutionary advantage over their peers when it comes to migration. And it wouldn’t take long, in evolutionary terms, for something like this to manifest itself across populations.

Facts About Sharks

No comments

Sharks are a special type of fish that do not own any bones in their body, instead they own cartilaginous skeleton. The sharks are considered the kings of water as the lions are the kings of the jungles.

There are about 440 species of sharks distributed in all the oceans and seas over the world. It has been confirmed that there is one species of shark that can swim in the fresh water of rivers, it is the bull shark.

The shark have a very strong smell and hearing senses, which allow the shark to locate the preys easily. It can also detect the prey direction due to the vibrations of the water.

Although the sight sense is not as strong the other senses, but the fact that the sharks eyes are in the sides of the shark’s head widen the range of sighting.

Most species of female sharks give birth of 6 to 12 babies, but rare species of sharks lay eggs. The baby sharks called pup. The female shark give birth of her pups after a period that range from 5 months to 24 months according to its species. Some female sharks can in some cases reproduce without a male.

The sharks teeth are formed in several rows that range between 5 to 15 rows, this way the shark will always have some teeth, as the shark tooth do not have roots and it is changed every week.

The shark skin is so strong that it reaches four times the cattle’s hide. Instead of scales as the other fishes, there are small and sharp plates all over the shark skin.

The size of the sharks vary, as some species size is about 8 inches while other species would reach about 59 feet (the size of a school bus).

They got 5 or 6 gills on each side, while the other types of fishes only have one gill. The shark gills are not covered as most of the fishes that have flaps covering their gills.

The shark don’t sleep, they just stay quit for rest, most species have to keep moving in order to allow water into their gills for respiration.

The sharks can swim fast with speed that range between twenty and forty miles an hour, while one species called mako shark can swim with a speed that can reach up to sixty miles per hour.

white sharksNot all shark species attack humans, but only white sharks, tiger sharks and bull sharks which is the most shark attacker to humans. People killed by the lightning or bee sting are more than those killed by sharks.

Sharks are hunted for the meat, skin and liver oil which is full of vitamin A. The Chinese shark fin soup, cause people to hunt the sharks, cut their fins and threw them again in water.

The shark cartilage was used in searching for cure of cancer, as the shark does not get cancer, but the shark cartilage failed to get the tumors smaller.

batBats are the only flying mammals, as their two front limbs have changed to a sort of wings. The wings of the bats are completely different than the birds wings as they are panels of skin.

Bats are one of the nocturnal animals as they hide and sleep during the day in caves, deserted buildings and trees, they start hunting during the night, in order to avoid the birds.

Bats sleep upside down as they pin their legs on a fixed thing and hang their till the night.

There are more than 1000 species of bats. The bats can be classified to two parts about three quarters of the bats species depend on their food on insects and other small living organisms, while only about the quarter are herbivores. There are few species that feed on fish, frogs, small mammals or on the blood of the mammals.

The size of the bats vary due to the variation of the species, it start from less than half a centimeter till about 15 centimeters.

Most kinds of bats are poor visioned, they depend on their high sensitive sense of hearing, they produce ultrasonic signals this is called the echolocation. The echolocation allow the bats to recognise the objects in front of them and recognise the food according to those waves.

The female bat can only deliver one pup a year, she takes care of him for about two weeks.

Vampires are a type of bats that feed on the blood of birds, cows, horses and pigs, in rare cases they can even attack humans. When they bite their victim they cut the skin and lick the blood by their tongues.

Facts About Scorpion

No comments

Scorpions are considered a type of arthropods, they have been on earth since hundreds of millions years, as the scientists had found fossils for scorpions that allowed them to determine that long period.

Scorpions are spread all over the world except in Antarctica, although they can live overnight in the freezer. Scorpions prefer to live in the sand, forests and deserts.

There are about 2000 species of scorpions; only less than fifty species of the scorpions are considered man killers. Scorpions are considered one of the predators for their main food the insects, arachnids and small vertebrates. But in the case of the lack of food, they can even live for a long period were there is no food at all by slowing their metabolism to the rate of one insect on the year. But they still keep some power that even at such time, when food appear they can spring very quickly.

The scorpions have a pair of pincers, it uses to grab the prey in order to suck it out. They cannot eat, but they only suck liquids, so the venom it uses on to paralyze the prey will also analyse the inside of the prey to liquid that the scorpion would suck out.

Scorpions are most famous with their venom injecting tale, the venom is secreted through two venom glands. They keep their tale in the upright position all the time. The scorpion attack its prey and paralyze it by injecting the venom through its stinger (barb) at the end of its tail, then kill the prey in order to eat it, they also use the same techniques in the cases of self defense.

Scorpion with youngThe female scorpion is able to produce up to a hundred offspring, the number varies by the species of the scorpion. The mother carries her young scorpions on her back for weeks until they can live independently.

If the male scorpion was not fast enough, the female scorpion would eat him just after mating. The female can also eat her young scorpions in the case of the lack of food.

Scorpions are considered from the nocturnal animals, as they hide during the day and get active and start looking for its food at night.

Some scorpions have from 6 to10 eyes, although their seeing sense is weak. But their sense of smell is very good. The scorpions as all arthropods have 4 pairs of joint legs. The scorpion have a chitin exoskeleton that include ultraviolet light that makes the scorpion glow at night.

Facts About Ants

4 comments

antAnts can be considered the most common species among the insects. Ants have been living on earth for about 100 million years. There are more than 12000 species of ants.

Ants live in colonies that could reach up to millions of ants. The ant colony contains one winged queen or several winged queens according to the size of the colony, along with several fertile males and thousands of female workers and soldiers. There are colonies of ants all over the world except for Antarctica, and few uninhabited islands.

When ant workers find food they leave a secreted chemical called pheromone so they would know the way back.

Ants communicate with each other using chemicals. The ant that feels danger produces chemical signals (pheromone) in order to warn the other ants and it also use the chemicals to lead them to food. Ants feel the sounds by the earth vibration and they don’t hear as they don’t have ears.

Ants can eat everything and anything starting from fungus, through insects till they reach meat. As they are considered scavengers and herbivores, they can even described as predators.

Ants can carry objects that can reach up to twenty times its weight.

Ants have three pairs of legs with three joints each. The legs are so strong which enable the ant to run very fast, as fast as a race horse comparing to human when considering the weight of the human and ant.

The ants respire through her body where they have tiny holes that the oxygen get through and carbon dioxide leave through.

In most cases when the ant queen dies, the hole colony would die after a short period as the ant workers are sterile and the only fertile female is the queen.

the jaws of the ant1The jaws of the ant are very powerful, they use to cut the food in order to transfer the pieces to the nest.

The ant own two antennae that it uses in touching, smelling and in fighting.

The Eye of the ant involve many small eyes, so the ant eyes are called compound eyes.

hippopotamusesThe Hippopotamus or Hippo is the Greek name, which means the river horse. Hippo is one of the largest herbivorous mammals on earth. The hippopotamus has a big bold enormous trunk, very large mouth, huge teeth and short legs.

The hippopotamus has three strong senses, sighting, smelling and hearing.

The hippo lives in the rivers and swamps in west and east Africa, most of the hippopotamus live in Zambia and Tanzania.

Despite its short legs, it can run with a speed that can reach 30 Km per hour, it can also swim very fast. The hippopotamus spend the day in the water or the mud to keep its body cool.

Although the hippopotamus is an herbivorous animal, but it is considered one of the most aggressive animals, it can run down a human easily.

The hippopotamus live in groups that consists of a number of females young calves and few adult males, the group is lead by the strongest male.

hippopotamuses threatened1When fighting each other, the hippopotamus open his mouth widely in order to scare its rival.

The lions, crocodiles and hyenas are the greatest enemies for the hippopotamus as they hunt the small hippopotamus.

The hippopotamus is endangered because it is hunted for its meat and its teeth which is made from ivory.

The hippopotamus kills people in Africa more than the insects and snakes. But actually they just attack humans when they feel they are threatened.

Questions And Answers About Dolphins

No comments

dolphins imagesDolphins are amongst the most adorable as well as the most intelligent marine animals. Belonging to the Animalia kingdom, they are quite closely related to whales and porpoises. Found all over the world, they mainly occupy the shallower seas of the continental shelves. It is believed that dolphins evolved around ten million years ago, during the Miocene. They have a beak-like snout and sharp, conical teeth. However, it is their friendly appearance and seemingly playful attitude that has made them one of the most popular mammals, as far as humans are concerned.

Below are some questions and answers about dolphins

How do dolphins sleep?

Dolphins have to be conscious to breath. This means that they cannot go into a full deep sleep, because then they would suffocate. Dolphins have “solved” that by letting one half of their brain sleep at a time. This has been determined by doing EEG studies on dolphins. Dolphins sleep about 8 hours day in this fashion.

A dolphin’s behavior when sleeping/resting depends on the circumstances and possibly on individual preferences. They can either:
1. swim slowly and surface every now and then for a breath
2. rest at the surface with their blowhole exposed
3. rest on the bottom (in shallow water) and rise to the surface every now and then to breath.

How smart are dolphins?

The short answer to this is that we do not know. There is no reliable method to measure intelligence in humans across cultures, so it is not surprising that comparing humans, dolphins, apes, dogs, etc. is impossible. There are some indications of their potential: they are fast learners and can generalize (which is also true of pigs). Also they can learn to understand complicated language-like commands (which is also true of the great apes).

How much do dolphins eat?
Bottlenose dolphins eat several kinds of fish (including mullet, mackerel, herring, cod) and squid. The compostion of the diet depends very much on what is available in the area they live in and also on the season. The amount of fish they eat depends on the fish species they are feeding on: mackerel and herring have a very high fat content and consequently have a high caloric value, whereas squid has a very low caloric value, so to get the same energy intake (calories) they will need to eat much more if they feed on squid than if they feed on mackerel or herring. On average an adult dolphin will eat 4-9% of its body weight in fish, so a 250 kg (550 lb) dolphin will eat 10-22.5 kg (22-50 lb) fish per day.

How long do dolphins live?
The maximum age for bottlenose dolphins is between 40 and 50 years. The average age a dolphin can get (the life expectancy) can be calculated from the ASR Annual Survival Rate (the percentage of animals alive at a certain point, that is still alive one year later). For the dolphin population in Sarasota Bay, the ASR has been measured to be about 0.961. This yields a life expectancy of about 25 years. For the population in the Indian/Banana River area, the ASR is between 0.908 and 0.931. This yields a life expectance between 10.3 and 14 years. So the actual life expectancy differs per region.

Strange Facts About The Formidable Hunter

2 comments

lion imageA Formidable Hunter

Found in Africa and the Gir Forest of northwest India, lions are formidable hunters. Prides, composed of four to six females, work together to take down large prey, such as zebra, wildebeest, impala and buffalo. Hunting skills are developed as cubs through the use of play-fighting among relatives. A lion’s diet also consists of small rodents, hares and reptiles, which can be hunted and killed by a solitary lion.

The King of Cats

Males live in pairs or small groups until they’re able to take over a pride. The males defend their large territorial areas against other male intruders to protect their mating rights with the prides that live within their territory.

Armed to the Teeth

strange formidable hunter factsA lion’s back teeth (called carnassals) work like a pair of scissors, which comes in handy when tackling a fresh piece of meat. Though the teeth help cut up their meals, lions don’t actually chew their food, but swallow it in chunks, using only one side of their mouth at a time.

 

A Manicurist’s Nightmare

odd factsA lion’s claws are not only very sharp, but also retractable, which helps maintain the big cat’s slice-and-dice capabilities by preventing injury during play. Their claws grow as a series of layers. These eventually shred to expose new claws that can reach lengths of up to  1 1/2 inches from the base to tip.

Prickly Enemy No. 1

weird factsThe lion’s worst enemy might come as a surprise, as the culprit is the size of a small dog: turns out the porcupine is the thorn in the big cat’s side, or rather mouth, as a lion tricked into sniffing the clever porcupine’s sharp quills often ends up with one or more stuck in its jaw for life.

 

Competitive Eater

formidable hunterTalk about a glutton! A lion will eat around 40 pounds of meat in one sitting on average. It then follows up its meal with the ultimate food coma, as it snoozes post-gorge for up to 24 hours.

 

Girl Power

strange factsMaybe the phrase “the lion’s share” should be revised to “lioness’s,” because when it comes to putting food on the table, the female pulls the most weight. Lionesses not only secure dinner but serve the males first, even before the cubs!

Breaking the Sound Barrier

Though a lion can’t actually roar until it’s 2 years old, once the switch is flipped, it’s hard to ignore. The mighty bellow used to ward off predators has enough force to raise a cloud of dust and can be heard up to five miles away!
