First animals which live without the need for oxygen found in the depths of the ocean

We have been all taught in school that animals need oxygen to live. We have also been taught that there are exceptions to every rule. I am mentioning these two "facts" because today I learned by reading an article, which indicated that scientists were exploring the Mediterranean seafloor and have discovered the first multicellular animals which do not need oxygen to live! 


According to the website: http://www.wired.com/wiredscience/2010/04/anoxic-animals/#more-20278

"Some types of bacteria and other single-celled organisms can live without oxygen, but nothing as complex had been found as these three species of Loricifera, a group of marine-sediment dwellers who inhabit one of Earth’s most extreme and little-known environments."
“The discovery of these life forms opens new perspectives for the study of metazoan life in habitats lacking molecular oxygen,” wrote researchers led by Roberto Danovaro, a marine biologist at Italy’s Polytechnic University of Marche, in a study published April 6 in BMC Biology."
"Like other Loricifera, the new species are sub-millimeter–long, The new species, however, don’t have the mitochondria found in almost every other animal cell, converting oxygen and nutrients into chemical energy."
"Even the few parasite species once thought to be mitochondria-free seem to have had them at some point in history, and possess mitochondrial remnants that perform the same essential functions."
"Instead the new Loricifera species have structures called hydrogenosomes, which are found in some single-celled organisms and require no oxygen to produce chemical energy."
"The evolutionary history of these creatures is not known, but they live in an environment reminiscent of Earth’s oceans some 600 million years ago, before the deep seas were oxygenated and large animals evolved, wrote Comenius University (Slovakia) biochemist Marek Mentel and Düsseldorf University (Germany) biologist William Martin in an accompanying commentary."
"These “fascinating animals” provide a “glimpse of what a good part of Earth’s past ecology might have been like,” they wrote." You can see what these animals look like by going to the following website:

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed



Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia



A person's true wealth is the good he or she does in the world. - Mohammed



Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein



The best way to find yourself, is to lose yourself in the service of others. - Ghandi



The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller



Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns



Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama



Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -



Milan Kundera, The Unbearable Lightness of Being



The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
