The Weedy Seadragon an Australian Icon

Australiana. Weedy Seadragons (phyllopteryx taeniolatus) lives only in southern Australian waters. The fish are quite large, growing to 46cm. They are redish with yellow spots and blend in with their surroundings.  Their red, sandy color does not show against the weedy background as they have green weed-like appendages. Seadragon males incubate eggs. A female puts about 200 eggs into a brooding pouch on the male during mating. The male fertilizes the eggs in his pouch. The young take two years to become mature. When seadragons die they are preserved by bony plates. These can be found washed up on beaches. Yearly rings are "recorded" in their ear bones. They live for five years. Seadragons are a barometer for climate change. It the environment deteriorates many die off. ◆ Australiana by Ty Buchanan   ◆ Tys Country Amusing Animal Photos Odd Weird Things Articles News Reviews ● Vista Computer Solutions                Australian Blog   ★   Adventure Australia ALL

Lithium Batteries Function by a Dangerous Chemical Action

Chemistry - Phones explode because lithium operates by chemical action. Let's not kid ourselves here: The iPad has had battery "explosions" just as much, if not more than Samsung. It is just that Samsung is more outspoken about issues. Apple believes that if it ignores a problem it will go away. I would like to see the real statistics on all phones. Batteries operate by chemical action. What you learned at school was that chemicals are dangerous. The unexpected sometimes happens. Lithium has the capacity to store a lot of energy. This pent-up power is always looking for a way out of its container. Though the incidents of phones catching fire is very low, the mere thought of something exploding in your pocket is frightening. Lithium batteries are notoriously unstable. They have caused fires on aircraft. Thankfully, no one has yet been killed. We do not have any alternative to lithium batteries. They are the most efficient and can be made very small. Consumer

Song Birds Originated in Australia - Science

The first singing birds originated in Australia - science. Singing birds originated in Australia. This is true. Just when they moved to other parts of the world is not yet clearly known. Evidence from DNA sequencing and fossils point to this happening approximately 23 million years ago. They first "hopped" from island to island until they reached Indonesia. From there it was easy for them to spread to Asia. The progression to populate the world occurred rapidly, like when humans moved out of Africa.  It took only a few thousand years for the initial "breakout". Birds of song could not leave Australia before 23 million years ago as Indonesia before that time was a small island and there was a huge distance of ocean for the birds to cross to reach other land masses. Half of all bird species are song birds. The only continent where they did not go is Antarctica. This is a mystery because penguins are birds, so the cold barrier is not significant for birds.  Man

Volcanoes Once Erupted Zircon Gemstones - Science

Science - Research in Western Australia shows super volcanoes erupted zircon gemstones. The surface of Earth was once covered in diamonds, well a very close imposter anyway. Australian scientists have just found out that a super volcano spewed out zircon crystals all over Australia.  It is a gem stone in many more colors than diamond. Samples from drilling in Western Australia showed particular crystals should have not been there. They were different from naturally occurring ones eroded from rocks. The "strangers" were 2,300km from their volcanic source. The great distance from erupting volcanoes indicates that the volcanic explosions 106 million years ago were much larger than previously thought. Australia must have been a very violent place in the past. Many animals would have died out because of the eruptions. ◆ science  CScience by Ty Buchanan   ◆ Tys Country Amusing Animal Photos Odd Weird Things Articles News Reviews ● Vista Computer Solutions
