A new kind of Pancake found in the Amazon it feeds on a fallen tree on the Santa Ana de PerÃє river in 2006. Other species of loricГЎridos (known as catfish or siluriform) use their teeth to scratch the organic matter from the surface of the sunken wood. The new species, still unnamed, is among the dozen species of Pancake known to digest wood.

However, the Pancake in general they are not able to digest wood. They only absorb the associated organic matter: algae, microscopic plants, animals and other remains. The wood passes through the fish and is expelled as excrement.

В "The fish passes the wood through its intestines in less than four hours, something incredibly fast for an animal that supposedly digests wood," said Donovan German, a biologist at the University of California, Irvine, who investigates the digestion of these particular fish .

The tubular-nosed lake

This died fruit lake with a tube-shaped nose (Nyctimene albiventer), which became a sensation on the Internet, is only one of the almost 200 species found during two scientific expeditions to Papua New Guinea in 2009.

Although it had been observed in previous expeditions, the lake was documented as a new species. Like other fruit bats, it spreads the seeds of the fruit it eats as part of its diet, and this flying mammal is crucial to the tropical forest ecosystem.

The squid worm

Is it a squid? Is it a worm? At first, this new species left the Census of Marine Life researchers perplexed, so much that they threw in the towel and called it a squid worm. This ten-centimeter long creature, discovered through a ROV 2,800 meters deep under the Sea of ​​Célebes in 2007, turned out to be a member of a new class family Polychaeta or polychaetes (anids).

The study on this creature was published in Biology Letters in 2010, and he was baptized as Teuthidodrilus samae or В «samaВ squid worm» (sama it is the name in bayao that receives an ethnic group from the Philippine Islands, not far from the place where this new species was found).

Nature is full of species with amazing characteristics. We discover the most curious

Earth is full of life. Living beings populate each and every corner of our planet, from the most populated areas of the big cities to the most remote and unknown corners. Quantifying the number of species that populate the Earth is an impossible task, so there are only approximations. The specialists affirm that since the planet arose about 500 million different species have populated it and that since then all but 1% have been extinguished.

Thus, it is currently estimated that there are about 5 million species. The vast majority, however, remain unknown to humans. In fact for now we only have cataloged a little less than 1.5 million species, mainly insects, microorganisms and marine animals. Scientists believe that although we already know two thirds of terrestrial creatures, 99% of the animals that inhabit the sea floor remain a mystery to discover.

This enormous diversity explains that we can find animals of all kinds on Earth. Only a few are known to ordinary mortals, while the vast majority are absolutely unknown to us despite being cataloged. Although all are unique and are part of a natural wealth worthy of being preserved, some of these animals produce more strangeness than others. In these lines we have brought together those who may be The 10 rarest animals in the world:
