Giant Mantis Religiosa.

Normally when we see a Matis religiosa, also known as Santateresa, not give us any objection catch it. It is slightly larger than a grasshopper and it can do anything to us. But perhaps we would not be so confident if we saw one mantis 20 cm, a giant mantis religiosa able to hunt birds, rodents and even small lizards. They are even capable of devouring people.

I've told people ... I was wrong ... The truth is that this usually happens the other way around?; lizards, rodents and birds eat the mantis.

The giant mantis is called stick mantis giant Malaysia (Paratoxodera cornicollis) is probably the largest mantis that exists, and is called "stick" to resemble sticks-bugs that blend with their surroundings and appear chunks vegetation. And this ability is that used for hunting, stand still, hidden, hidden among the branches until a prey comes close enough to be able to catch him in his strong front legs.

Glass Frogg

Is there a group of frogs that have a peculiarity which other animals do not possess even the other frogs: their skin is transparent ... and  glass frogs (or glassfrogs) or Centrolenidae. Imagine gut hurts and you look and see that you've eaten steak is hard to digest or view the heart and it hurts and you see it stopped, would be watching your own heart attack, although it would be a rare thing to describe, 'd know exactly what's wrong and therefore what is the best course of action. It seems silly that it is not really, in fact thanks to its transparent skin, science uses frogs to study the incidence of diseases, such as cancer onset and development without opening carcass to check your progress.

Well, this frog's skin is transparent, we can see its organs, the guts, the elongated stomach, veins, liver, heart and even the eggs before deposit in place. However, it is not easy to see because they are very small, little more than 2 cm, although some species and even exceed twice the size. Also, are nocturnal ... imagine a transparent, small and nocturnal frog hidden in the jungle ... almost impossible to see at a glance.

The female leaves between 18 to 30 eggs near water. When touched, these are broken and leave the tadpoles to water. Until this happens, the male is watching the sunset from potential predators. For predators know it's there, it emits a peculiar sounds.

It's a frog that lives in the wetlands of central America and the tropics of South America. And conservationists try to make an effort to publicize that this frog is in serious danger of extinction. The pollution of rivers, water in general, habitat destruction are getting increasingly fewer copies remain free.

Gambian pouched rat

Practically across Africa we can find the  Gambian pouched rat (Cricetomys gambianus), a huge colonizing rat is expanding around the world. Maybe everyone ye may know or ever seen a sewer rat. Those famous for being the protagonists animals, carriers and propagators of rabies and plague, the Black Death that killed millions of people in Europe and Asia, 800 years ago. Rat gray or black, are nothing compared to the  Gambian pouched rat. While the gray rat .... wait wait .... maybe you will get a comparative example, LOOKING DOWN.

Black Rat
 22 + 24 cm

 Total 46 cm

1 ft
 230 gr.

9 Oz
Brown Rat

 27+22 cm

Total 49 cm

1 ft
 520 gr.

18 Oz
Gambian pouched rat

 48 + 45 cm

Total 93 cm

3 ft 
 1500 gr.

59 Oz 

As you can see, the  Gambian pouched rat is 3 times heavier than the gray rat, the most common. It's almost as big as a cat, and I think that cats have to be very hungry to hunt  Gambian pouched rat.
The problem is that this rat is spreading worldwide. And wherever they go, they may not have predators and can become an invasive species that can of wiping out everything.

For example, they can be a big problem for the birds, and their eggs can be eaten by these rats, and can wreak havoc on entire populations of those regions colonializan. The United States has prohibited the sale of this animal as a pet because it is suspected of being behind pandemic in prairie dogs, and certain species of monkeys.

The "good" of these rats is that even being omnivorous and are able to eat tiny animaletes, seem to prefer the fruit and vegetable food. But the good, without quotes, is that man has taken advantage of its good sense of smell and its docile nature, and have achieved good results and is used for the detection of persons with tuberculosis, as it is able to smell the disease and is also used to detect landmines, being little heavy not activate the pump.

Gambian pouched rat do not have a very good view and virtually moves using the smell and hearing, and their habits are nocturnal ....

The strongest .... in Africa have been recorded fatal attack on human babies perpetrated by these rats. But let's be fair, that's an anecdote. The shark kills 300 people a year, the cobra kills 50,000 people, mosquitoes 2,000,000 or that our species has killed millions of sharks, millions of spiders, mosquitoes, lions, rats, wild cats, wolves, buffalo, chickens, snakes, etc ...

Great Potoo

Imagine you go at night in a forest, hear the howl of a wolf, a movement nearby and hooting and suddenly scared you turn on a branch and see someone watching you:

Quiet is not a spirit after death, those eyes belong to a animalete, the Great Potoo (Nyctibius grandis).

This bird is a species of night owl. At night spreads its wings proportionately long, and quietly stalks its prey, is dedicated to hunting flying insects: as beetles, crickets, grasshoppers or moths.
But their wings are not the only thing that has large, as other nocturnal owls, their eyes are huge. They are specialized to capture the low light in the darkest environments.

It is found in tropical forests of America .... good find. They are very difficult to see, perhaps for its plumage and nocturnal habits, and in general, they are considered rare. Personally I think so.

Are currently not in danger of extinction. Adults have no predators only eggs are sometimes eaten by howler monkeys and spider monkeys, for some mustelid and large birds of prey.

Salmon Shark

We know that the shark is a perfect killing machine. Its body has changed little in thousands of years because its design is virtually unbeatable. But we could say that the ability to kill could be improved if it were a warm-blooded fish, thus increasing muscle capacity, and decreasing your reaction time.

To nature, evolution, or whatever you want to call it, has already created a shark so called  salmon shark or Lamna ditropis. This still being a fish, is warm-blooded, maintaining a temperature of between 21 º.

I personally reminds me of a big tuna. It has a compact, strong body, pointed snout and flat, with large eyes and a large mouth full of sharp teeth. It is dark gray on the back and whitish belly. On the side is pinkish characteristic traits that make it and have earned it the name of Salmon Shark.

They can measure over 3 meters (9 ft.), and some witnesses say they have seen specimens of up to 4.5 meters (15 ft.) and 550 kg (1220 lb).

Dispatched by both Eastern North Pacific and Western. And a funny thing happens here that experts have not yet been able to explain. In the eastern regions are the females who maintain control over groups of sharks, however, in the western regions, the male domination is almost copies.
