Medicine & TechnologyPumpkin spiders are out in full force this Halloween season with their vibrant orange abdomen that makes it look like a jack o' lantern but with eight legs. But spooky as they are, these spiders are harmless.
Perhaps the most popular species of spiders are the brightly-colored, hairy tarantulas - and a new study might finally explain how these eight-legged creatures exist virtually everywhere on the planet.
Mouse spiders can be found across Australia and often falls into the swimming pool. But experts warn people that these venomous spiders can usually survive underwater and their bite can cause severe pain and illness.
Australia has always been a land of the strange and bizarre. It is home to some of the world's most unique animals, from the kangaroo, to the wombat, to the lovable Tasmanian devil. So the fact that it's raining spiders should come as no surprise.
When you watch butterflies flutter through the sky and lobsters waddle in the sea, you may not readily believe that the two far off species have anything in common. But along with spiders, butterflies and lobsters share quite an interesting collective history-one where an ancient ancestor may have emerged from the sea. Cover the ocean, the land and the skies above the radiation of species into many forms are believed to have originated with a common ancestor as long as 508 million years ago. And in a new study published this week in the journal Paleontology researchers are finally giving a face to ancestor known as Yawunik kootenayi.
Add two more to the list. Not the species list, silly; the list of creatures to avoid when I’m visiting down-under. As it is, Australia has some pretty interesting, and sometimes terrifying, species unique to that region of the world. But with a new study recently published in the journal Peckhamia, researchers are adding two new arachnid species to the list. And they’re quite the colorful bunch.
