Glow worms can tell the time. Yes it's true! An Australian researcher has found that glow worms "light up" during daylight hours, even though they are in total darkness 24 hours a day. It is only a Tasmanian species of glow worm, however. Mainland species glow day and night. It is not known how they detect that it is daylight outside the cave. It is thought that a chimney effect occurs in a cave, whereby air is "breathed" in and out from outside. This probably causes a change in temperature. Glow worms possibly use the temperature stimulus to choose when to glow and when not to glow. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--australia.blogspot.com . . . . . . . . . . . . . . . . . .

Things have been falling from the sky for hundreds of years with no solid explanation. It has been claimed that marble pillars from ancient Rome fell gently to earth a century or so ago. This is deemed to be just a story, but Frogs, fish, worms and squid being dumped onto the earth during rainstorms is fact. The main theory is that they were picked up from small shallow ponds by whirlwinds. This is just theory and has not be proven. Indeed, no one has observed actual "pick up" occurring. When a fall has taken place more of the same can be expected. The species of frogs and fish are not always local. They are from different climes than the dumping location. Such passengers of storm have one thing in common: they are generally small. Although stories of small creatures falling with rain are usually much the same, some cases are truly extraordinary. Fish fell from the sky during a Singaporean earthquake in 1861. Leonard Bourne was running in a rainstorm in 1966 in Australia when...
