New Scientific research about sharks:they help scientists understand the state of the World's oceans
New scientific research has been released to the public today for the first time, and it gives scientists a better understanding of the relationship between aquatic life which sharks interact with and this life's relationship with its environment. As well because of this research scientists now assert that they will have a benchmark for the health of our oceans.
"The joint study between researchers at The University of Western Australia and The University of Queensland looked at the visual adaptations of four species of wobbegong sharks, which are also known as carpet sharks."
"The study examined the western wobbegong (Orectolobus hutchinsi) and the dwarf spotted wobbegong (Orectolobus parvimaculatus, which are both found off Western Australia, as well as the ornate wobbegong (Orectolobus ornatus) and the spotted wobbegong (Orectolobus maculatus) found off Queensland."
"The researchers found that the eyesight of the western and ornate wobbegongs was suited to both day and night activities, whereas the spotted and dwarf spotted wobbegongs were better adapted to low light conditions."
"WA Premier's Research Fellow and Winthrop Professor Shaun Collin, Associate Professor Nathan Hart and UQ's Dr Susan Theiss said the results would lead to a better understanding of the sensory systems of marine life and help scientists better predict reactions to a change in light conditions."
"Dr Theiss said the sharks' visual adaptations were linked to factors such as their diet, habitat, whether in shallow or deep waters, and their reproductive behaviours."
"This research is important in establishing general trends and predictions in biogeography and ecology that we don't yet have data for," Dr Theiss said. "
"If we can understand their habitat, we can extrapolate and make informed decisions about other sharks and rays and how they are able to survive in different light environments.

Thoughts worth thinking about
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.
