The Bonobo lifestyle

The bonobo (Pan paniscus) is, among all, the closest ape to modern humans, more like gorillas, orangutans and even chimpanzees. In fact resembles the chimpanzee, but it looks more graceful, his forehead is wider also has long hair on the head, females have slightly prominent breasts in contrast to the flat breasts of other female primates, although not as prominent as those of human females. Differences that make it more like humans. So they erected to the ground to navigate.

In fact, after deciphering the DNA, it was found that bonobos are closer to humans than gorillas. Share, like the chimpanzee, 98% of the genome. Therefore, some experts propose to the bonobo chimpanzee and included in the genus Homo .... Homo sapiens as we are.

It resembles the chimpanzee .... but ... Why is it special?

In the relationship with their peers.

First, they are considered more intelligent than chimpanzees, and can learn up to 500 words they use to communicate easily with us.

And second, while chimpanzees are considered aggressive and territorial, bonobos are very peaceful. Chimpanzees plan to attack other males outside the clan, make war against other clans and kill other apes from time to time. In contrast, bonobos, are very peaceful. Their social structure is matriarchal and solidarity. The females are the leaders of the clan and the tension that is generated from those conflicts involved in the relationship between members living together, calm through sex, not violence.

Sex plays a major role in the societies of bonobos, as they are used as a greeting, as a method of conflict resolution as a means of reconciliation after them, and as payment through favors both males and females in exchange of food. Bonobos are the only primates (besides humans) that have been observed by all the following sexual activities: face-to-face genital sex (primarily female with female, followed in frequency by the female-male sex and male-male rubs) , tongue kissing and oral sex.

Anyway, I like to think that people are closer to the peaceful bonobos than chimpanzees aggressive, though, seeing as provoke wars, we kill each other, we destroy, we end up with entire species, and we settle for social inequalities, I must say we are like chimps, would be quite an insult to them.

The Takin

This animal unknown to many has many characteristics that make it a very interesting animal. Consider first some information about this animal.

The Takin (Budorcas taxicolor) is in the mountainous regions of civilization hidden in the mountains of the Himalayas and western China at an altitude of 1.950 to 4.500 m.

Its weight rarely exceeding 350 kg and his height is 130 cm cross. They are herbivores and their predators are bears and wolves (other than the man who is to all other species).

Now let's look at two curious features of this animal.

1 - His appearance is strange, short legs and a sturdy body and is also the bovine plumper. Not the heaviest, but in relation to its size, the more robust.

2 - Although this animal may appear to many, by the countries where it is highly valued, in fact it is the national animal of Bhutan.

And finally, 2300 years ago, in Greek mythology appears in the story of Jason and the Argonauts and the Golden Fleece. Well, it is thought that the golden fleece fleece refers to the Takin, a ram yellow, golden brown hair long remembered gold.

Giant chimpanzees.

They really are not chimpanzees, although they seem a lot but larger. In fact, do not quite know what it is or how to classify these beings were discovered in the Congo in 2004.

Similar to chimpanzees but not as robust as the gorillas. Experts do not agree.

The Scientists are considering several theories about the apes, which are a new species, which are giant chimpanzees but behave like gorillas, or that are hybrid, the product of mating between gorillas and chimpanzees.

If, as suspected, it is a new species, the finding would be one of the most important in decades. But this will not know for sure until the DNA is analyzed.

And apparently, but for us these are "new" apes in the area and were well known to its inhabitants. They described the ferocious animals like monkeys and strong even able to kill lions.

And these chimpanzees weigh 100 kg (twice that chimpanzees we know) and very muscular. And I assure you that the muscles of these giant chimpanzees have twice the force that a bodybuilder with the same weight.

Cuckoo's Egg.

Possibly the most notorious bird with the animal world than the vulture or a raven, possibly the most notorious bird is the common cuckoo or Cuculus canorus.

Classify the behaviors of animals in our culture, and adjectives are attributed to the cuckoo are unflattering: operator, cheater, liar, fraud, etc ... But like I said, are just classifications of our moral system to a survival tactic, which, however, is as valid as any other.

What causes this animosity towards the cuckoo is taking advantage of other poultry farms, deceives and makes slaves. What happens is that when the cuckoo bird detects that a (usually
small, insectivorous bird) is laying eggs, the cuckoo deposits in the nest egg with these. The Cuckoo's Egg will be just the same, very similar in color, size and shape to host bird's eggs (above). Sometimes they are so alike that even the most expert ornithologists know the difference.

Then, as all eggs are equal, the host birds, hatch and care for the state of the egg that is not theirs, but the cuckoo.

But the Cuckoo's plan does not stop there, once the eggs hatch (usually the cuckoo is first) the cuckoo chick to not even get rid of all the other eggs, either pushing them to throw the nest or until just pecking with them. In this way ensures that the food brought by parents, guests birds, is just for him. Deceived, birds fed the only guest who is not her son but the cuckoo, and is also the murderer of the dead children.
In the top right image we can see the cuckoo, much larger than their adoptive parents, still fed by them.

Watch this video You'll be amazed to see how it works the cuckoo.

Emperor Butterfly.

The emperor butterfly, as its name suggests, is a butterfly that is above the others, is the species name of a butterfly is considered one of the largest in the world. Rather .... THE GREATEST.

Emperor Butterfly (Thysania Agrippina), is also known as bird-winged butterfly, white devil, butterfly ghost, witch big gray. And it is certainly larger than many birds.

Is large, with a wingspan of up to 35 cm. And despite his major and his royal name, is an animal that is endangered due to destruction of their
natural habitat.
It is a moth of powerful flight, easily confused with a bat or a bird. A
often close to the houses, attracted by the lights. Some superstitious people ascribe bad omen.

Sorry I can not show more pictures.

Desmodus rotundus or common vampire.

Vampires have given rise to many legends and stories of yesteryear who have forged a popular place in our unconscious.Possibly the best known is the story of Dracula or the Chupacabra,fantastic creatures that attack their victims (humans and animals)sucking all the blood and literally leaving them dry.

The vampire Desmodus rotundus is the best known and most extensive habitat in the world. The most characteristic feature of this vampire is the way you eat, of course, is sucking the blood of their victims.

At night is most active, and is nourished by blood, mostly fromlarge mammals such as horses and cattle. It has been observedfeeding on the blood of chickens and also attacks humans.

The first thing is to bite, a bite surface in order to go licking theblood from the wound. The common vampire bat's saliva has a powerful anticoagulant (which began to be used in medicine) and prevents the wound from closing until the end.

There are two main dangers for the animal victims of this mammal.

1 - If an animal (a cow) is attacked by several individuals of vampires, and for several days. Literally left without blood, causingthe death of the animal.
2 - You can transmit diseases, including rabies.

But the common vampire bat has a nice side ... Their high intakemay share with others of their species to survive. Because onlythose who receive the food could die because they can not be more than 48 hours without eating.

As I said before, the bad reputation of this animal does not correspond with reality. It was possibly attributed due to the damageproduced in animals that fulfilled an important role in rural societiesof yesteryear.

You may be interested Acerodon jubatus.

The common swift, the world's fastest bird.

The common swift is a bird of extraordinary. Although we see many times and used to their presence, the Swift is probably better suited to the bird fly around the world.
First, the Swift is considered the fastest bird. Flies at a speed greater than any in its class. While it is true that the Peregrine Falcon can reach speeds higher (200 mph), these speeds are reached in fall, not horizontally.

A Swift may be flying at 150 mph and the alpine swift to 170 mph. A rate is not negligible.
Just see these wonderful birds shows that your body is adapted to speed on the fly. Its anatomy is the most aerodynamic of all birds (like the swallows). It has adapted wellto air your legs have become shorter and useless. Not being almost used weredownsizing and making them almost useless for travel by land. Eat, drink, mates and even sleeps in the air. To sleep in the air at dusk, rise and rise and rise as high as you lose sight, they begin to plan and sleep until dawn.
Another curiosity: When the Swift is subjected to inclement weather or a shortage of food, you can enter a state of near hibernation or "torpor." Thus, they consume less energy. Swifts adults can survive two days in this state and the chicks can survive and even five days.

Another more curious: How many years did not touch the ground only to nest and his paws are not developed, they need to make nests at some point. So drop and start flying as their feet are not allowed to walk, run or jump.

Sepia colors.

The common sepia (Sepia officinalis) is a fascinating animal ... Believe it or not. We're used to seeing them in the dish, with some seasoning, white and tasty. But make no mistake, this animal is amazing. Going to see some features.

Sepia size can vary up to 65 cm long and can weigh 4 kg, although animals in warmer seas are generally smaller.
They are very intelligent, and why not ... even resentful. When they are small and are vulnerable to certain predators, retained in his memory the image of a predator. And then when they grow up, they come and hunt prey over others.

But it is the most fascinating colors. Show the color as a sign of his mood. During mating display colors with the intent to intimidate their opponents. And when hunting know how to dress, the colors blend in around him. Can imnotizar prey and these, Abobo, stalk left until the cuttlefish is close enough to launch his attack. They have eight arms with four rows of suckers each and two long tentacles to capture prey, which, however, it retracts into the bags under the eyes if not used.
But not "just" that also can vary the texture of your body if you want to blend to be virtually invisible.

This is a video of the Wizard of colors. Sepia hunting.

Besides that, is a survivor who has gadgets to escape their attackers. Has a bag of brown ink spilled in the water. This lead to dismissal from predators and just in time to flee.

Another aspect is the view you have, have developed eyes that let you see in the dark, a general feature of other cephalopods such as the mysterious colossal squid.

Tyrannobdella rex.

Today my friends, I'll show you an incredible animal but also detestable. An animal that if we saw it in action, rather not have seen, even we had hoped that did not exist ... if you are ready, read on.

Do you see the black spot that looks for that person's eye? Well, this is nothing more and nothing less than a leech, the leech T. REX. It is huge (for what it is) from 5 to 6 inches long and has a row of sharp teeth that cling to the meat of the mucosa and do not release ... subject once suck suck and suck and are terrible. The bite is painless, because saliva contains an anesthetic. It also has an anticoagulant that ensures the flow of blood as it is suctioned.

Makes relatively little is known, in fact, was discovered in the nostrils of a Peruvian girl who went to the doctor because I felt that something was slipped inside the nostrils. And one thing is for sure, a lot of strength must have to enter through the nostrils of a person.

Anyway, if you want to dabble in the desirable South American rivers, have one thing in mind: an enemy awaits you. Hehehe

The coconut crab or Birgus latro.

You thought that this image was not real? Yes, this picture is real, the image of a huge crab, the heaviest of all the crabs, and after the giant crab of Japan, is the longest.

This is the coconut crab or Birgus latro. And why is called the coconut crab "... well because its huge claws and strength that is in them is able to break coconuts. It also receives other names like "robber crab" or "palm thief" to be considered a thief who steals shiny objects houses the Pacific and Indian Ocean (found especially in Christmas Island or the Seychelles.
But her stunning looks should not intimidate, is practically herbivore rather fructívoro, although sometimes eat decaying organic foods including the bodies of certain animals or animals very slow and juvenile sea turtles.

The coconut crabs live on land, econdido between rocks or in burrows, which is why it is "nose. " Nose is not as good as ours, but unlike their peers (other crabs) that have specialized organs called aestetas on their antennae to determine both the focus and direction of an odor, the coconut crab has different sense organs that allow odors in the air. It has an excellent sense and can detect interesting odors over long distances, for example, the smell of grilled meat, bananas and coconuts call your attention especially as potential sources of food.

Weight varies by age and sex, but estimates can easily reach the 10 kg.
Let's see how they break a coconut.

The gaur, gayal or mithun.

In India, Nepal and Indonesia there is a bovid (Family Bovidae that brings animals like antelopes, oxen, bison, buffalo, goats and sheep) related to domestic cows and has a record size of all the species of the family .

An average adult male can easily reach 2.2 meters (6,6 ft) in height at the withers (which would be the highest point of the body without raising the bass) and over 3 (9,8 ft ) in length. Muscles and more muscles to reach a weight of 1000 kg (2.200 lb).

Like all the bovines, the gaur, gayal or mithun,are strictly herbivores. They eat both grass and tree leaves and bamboo shoots. The coat color ranges from reddish brown to dark brown, with broad forehead and legs below the knee white. The horns, fairly short and black tip, born on the sides of his head and arching upwards.

Predators include wolves, Cuon, tigers, leopards, bears, Tibetan and men, who have pursued primarily for their meat.

It should be like cape buffalo.

Little is known of the blobfish, an animal with a truly strange and peculiar aspect. It is a fish, and lives in depth. Hence its gelatinous. To offset the high pressures on the ocean depths, this fish has a gelatinous meat, with a density almost equal to that of water.

With that body is easy to stay afloat without effort, and effort does not do much because it is dedicated to walking and eating the food that passes in front of his mouth.

Another feature of these fish is that they have large eyes that let you see in the dark. Come on, all this makes the appearance of this pezecito be something funny. Look at this picture:

Apparently some 250,000 have been recorded blobfish, of which 30,000 have beenstudied.

This fish is almost unknown, is in danger of extinction because of fishing practices that are practiced in areas where it lives. Deep trawlers are looking crabs and lobsters offthe coast southeast of Australia, that capture by "accident" this and other fish andindiscriminately destroying the lives of thousands of species.

Turritopsis nutricula... an immortal animal

Some time ago we talked about the Water Bear or tardigrades, an animal alive can withstand the most extreme conditions, for example, live in space or living a dormant state for thousands of years.

But the animal that we see now is almost as surprising: AN ANIMAL IMMORTAL.

No esque dodging bullets or become invisible to predators. It is easier to explain yet,but much more fascinating because it is real.

Nutricula Turritopsis is a polyp, a jellyfish that is considered immortal because, unlikeall other components of the animal kingdom, this becomes a child when you aregetting old.

I mean, an animal is born, grows, reproduces and dies (is typical) and jellyfish as well.Jellyfish usually have a fixed stage (when polyps) and is fixed to a substrate, then theydevelop and become the jellyfish swimming we've all seen ... then reproduce, grow old and eventually die.

Well, the Turritopsis nutricula is medusa polyp and then, and played and then ...BACK to polyps ... It is believed that this cycle can be repeated infinitely and thus live forever.

I leave an explanatory video.

Giant golden-crowned flying fox, Acerodon jubatus

The Giant golden-crowned flying fox (Acerodon jubatus) is the largest known bat. Can reach up to 1.70 meters wingspan, slightly less than the Pteropus vampyrus and weighs 1.5 kg.
This curious animal is endemic to the Philippines, and is in danger of extinction as they hunt for years to eat its flesh. Another element is the deforestation of their habitat.

It is a nocturnal mammal and their diet is not the blood of their victims, but fruit, flowers, nectar ... Helps disperse the seeds when defecating and can live to 15 years.

Unlike other bats, flying foxes and echolocating filipino are not large eyes which allow them to see in the dark of the Philippine jungle.

Zombie ants and the fungus housed inside.

When we see a zombie movie, gives us no fear ... in fact often makes us laugh. But if it makes us laugh, it is only because we know that is not real and we see ridiculous.But in nature, zombies exist. They are called "zombies Ants."
In the humid and lush Thai jungle there is a fungus (Ophiocordyceps unilateralis) that is capable of penetrating the interior of a certain species of ant, and from within the handling on their behalf. Not only about this fungus and with this type of ant ... but hey, one day talk about these ....

The fungus requires the ant parasite which infects, to die in the most appropriate place for the fungus to grow and reproduce. Basically they are forced to find a wet and out of the sun, then the ant zombie, digs his jaw (on the underside of the leaf) and holds on tightly with his paws. At that moment dies, the fungus begins to develop, and the ant has served basis, whether as a shelter under exoskeleton or a base is to develop fully.

As a picture is worth a thousand words, I put a video here for you to see how everything happens.

View this process is truly amazing and so far, no one knows very well how the fungus can control the ant.

Common Raven or Crow.

The Common Raven deserves mention as one of the most amazing animals that currently exist on Earth. It's a smart bird, adaptable to various environments and with very peculiar characteristics.

As it is and then describe some interesting common crow.

The common crow is found throughout the Northern Hemisphere is the corvid species with the largest area of distribution. With Thick-billed crow, is the largest of the corvids and probably the heaviest passerine, at maturity, the Common Raven is between 52 and 69 centimeters in length and its weight varies from 0.69 to 1.7 kilograms. Common Ravens usually live 10 to 15 but some individuals have lived 40 years. Juveniles may travel in groups, but already formed couples stay together all their lives, each pair defending a territory.
The common raven coexists with humans for thousands of years and in some regions is so abundant that a species is considered harmful. Part of their success is due to their omnivorous diet, the Common Raven is extremely opportunistic, feeding on carrion, insects, food waste, grain, berries, fruit and small animals. Have revealed several notable shows resolution of problems in this species, suggesting that the Common Raven is very intelligent.

Let the curious:

The Common Raven has one of the largest brains of all species of birds. It also shows various skills such as problem solving as well as imitation and intuition.

It has been reported that crows are at other animals to work for them, for example by calling the wolves and coyotes to the place of a carcass. The canine then open the carcass, making it more accessible to the ravens. Also known to observe where other ravens hide their food and remember these places, allowing them to steal. The Common Raven is known for stealing shiny objects and hide as rocks, pieces of metal and golf balls.

Young ravens are birds of all players.

Crows attract vultures (eared, tawny, black) to open tough skins on carrion.

Crows attack pests harmful to man and transmission of diseases such as pigeons and rats. Watch the video.

Reduce pests such as cane toad Australia. This animal is not native to Australia and is considered a pest because any animal that wants to devour you find that is poisonous, not taking it no predators in the area. But the common raven has learned to turn and begin to devour the belly, which is the only part of the skin that has no poison.

Sea wasp or Chironex fleckeri.

The sea wasp Chironex fleckeri is considered the most poisonous animal on the planet. Although no antidote is capable of killing a person with the mere touch in 30 minutes. Within 20 minutes of the sting of stinging cells, begins what is called irukanjdi syndrome: begins an intense pain throughout the body, heart rate triples, doubles blood pressure, death usually occurs after a cardiac embolism.
The main body is almost square, translucent blue and green (so it is very difficult to distinguish at sea), of which 60 cilia or tentacles out of about 80 cm long each. It is almost transparent, making it very difficult watching for swimmers. Moreover, their bites are imperceptible.
Usually is found in tropical waters of Australia and other areas of the western Indian Ocean and Pacific.
But even if a dangerous animal, it remains one of the most beautiful animals to see.

Curiosity: Contrary to popular belief about their movement and unlike the common jellyfish, most of whom are blind, this species has four groups of twenty eyes. But it is unclear whether they can keep the light targets or how to process images as they do not have central nervous system. Nothing in pulses of 1.5 m / s, giving it enough speed to catch fish.

Fosa o fossa

The fosa or fossa is a species of carnivorous mammal of the family of viverrids. It is the largest native carnivore in Madagascar. Despite its strong resemblance both physically and customs with the canines and felines, the fossa is actually a representative of the viverrids, the same family that owns the genets, mongooses and meerkats. It is the dominant predator of the island and main hunter of lemurs after man.
The fossa is 80 inches long, plus 90 inches of tail with 15 kg.
The body is long, muscular and agile. The pits can run at high speed on the ground and climbing trees amazingly fast, thanks to the extraordinary grip on her bare feet and fitted with retractable claws (a characteristic typical of cats, but absent in other viverrids except in the pit). They may even jump from one tree to another as if they were small squirrels, jumps up to 6 meters.
They are really agile animals.
In Madagascar, the fossa is taken by an animal almost diabolical. Circulate all sorts of legends, but all unreal. In fact, they are usually easily to life in captivity, where they are docile and affectionate with their owners.

Mantis religiosa or European Mantis.

The mantis religiosa or European Mantis also called mantis, tatadiós, dragonfly, Mamboretá, blowgun, use, or dragonflies comepiojos is a medium-sized insect.
Have a large compound eyes on the head which can rotate up to 180 degrees and three simple eyes between the compound eyes. Its front legs, which keeps collected before the head in prayer, are provided with strong spines to hold the prey it feeds on. It is voracious and very common in warm places.
In the mating season the female mantis emitting pheromones to attract the male and at this time that happens the only moment in which males and females together. Females become very aggressive and the male mantis can lose your head for love. Indeed, the female may devour either before, during or after mating. The first bite is the head and, often, the male can continue copulating beheaded.

Tasmanian Tiger Extinction Mystery.

The Tasmanian tiger or Thylacine was by far the largest carnivorous marsupial of recent times. Its overall appearance is very canid-like. Total body length is around 1 meter. The tail length is around 50-65 cm. The tail itself is very thick close to the body and quickly tapers to a point. It is around 60 cm in height at the shoulder. The upper body is brownish/grey with a pale underside. There are 13-19 black vertical stripes that run from the mid-back to the base of the tail. The face is grey with white markings around the eyes. The fur is short and thick. Their skull has a length of 22 cm and the dental formula is: i 4/3, c 1/1, pm 3/3, m 4/4. Tasmanian tiger's long canines, shearing premolars, and grinding molars, all of which are quite similar to those of dogs. The feet are padded and leave a five-toed print. The females pouch is located by her tail and has a fold of skin covering the four mammae.
Tasmanian tigers lived only on the island of Tasmania in recent history, but fossil record shows that it was also found in New Guinea and Australia as recently as 3000 years ago. Competition with dogs brought by aborigines eliminated it in Australia and New Guinea. These dogs ran wild, becoming the dingo, which entirely filled its niche. A large population survived on Tasmania, where there are no dingoes. But when the Europeans arrived and settled in Australia and Tasmania the Tasmanian tiger was thought to be a livestock killer, especially when sheep were introduced in 1824. This was never substantiated, but because of this misconception the privet sector and the government hunted the Tasmanian tiger from 1830-1909 for bounty. In 1830, the Van Diemens Land Company, a pastoral company in Northwest Tasmania, introduces the first bounty on the Tasmanian tiger, claiming that the animal attacked sheep.

Extinction may not be forever after all; so hope the Australian scientists behind an ambitious project to clone the extinct Tasmanian tiger.
The project to bring the Tasmanian tiger back from extinction began in 1999 when Australian Museum scientists extracted DNA from an ethanol-preserved female pup in its collection.
We will see in a future if it is possible it to come back to the life, or as it has been said in several mass media, it is possible that the wolf marsupial is living , hidden from the man.Look that beautiful
