Though jellyfish have no brain, intelligence is built into their bodies. They appear to act on instinct to changes in the environment. Whether they have consciousness is not known. They swim better than any other creature. Swimming against the tide is their forte. Detecting the direction of currents was thought to be impossible without sight, yet jellyfish do it. Rhythmically moving their heads and forcing water out from their bodies, they are a jet-propelled swimming machine. Most believe that jellyfish just drift. This is not the case, They head straight for their destination, for example, usually in groups. Somehow they know that there are others of their kind with them, though they do not have eyes. Perhaps the animal uses the Earth's magnetic field as well as ocean currents to know where they are. Some scientists have suggested they use infrasound. ✴ Science by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blog

Nations in the Pacific are the first to be affected by global warming. The tide is literally coming in higher and higher. Children play in sea water as it enters homes built on the highest points available on small islands. The Australian Government's Pacific Climate Change Science Program (PCCSP) has released a report on the Pacific region. The last decade has been the warmest ever recorded. Acidity in sea water is also rising because there is more carbon dioxide. Cyclones are predicted to increase with greater rainfall. Day and night temperatures will be higher. While the report will help Pacific nations show what damage has been done by the developed world, it is doubtful advanced countries will assist financially. Knowing what will happen will help island nations plan for the future though the changes are already apparent as the sea takes over the land. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/Adv
