 Huntsman spiders engage in bizarre behavior of living together in harmony Huntsman spiders are named after their habit of hunting other arthropods such as cockroaches, crickets, and even other spiders. They’re the world’s largest spiders by leg-span, with the largest specimens reaching up to 11 inches across in diameter (though most are much smaller). But new research has revealed that huntsman spiders engage in another behavior that’s just as uncommon as their giant size – they live together in large families of multiple generations, called communal nests. What are spider colonies? A spider colony is a group of spiders that live together. These colonies can be found in many different places, including homes, gardens, and even forests. Huntsman spiders are known for their ability to live in large colonies. In fact, some species of huntsman spider can have up to 1,000 members in a single colony! That’s quite the family reunion. And these spiders don’t just congregate: they hunt tog...

 Demon geese of doom' laid melon-length eggs in prehistoric Australia Even demon geese had predators. Here, the large "demon duck of doom" (Genyornis newtoni) flees its nest, pursued through the extinct lizard Megalania (Varanus priscus). Both species lived in Australia approximately 50,000 years ago. (Image credit: Peter Trusler) Scientists have eventually cracked a 41-year-antique thriller approximately an ancient eggshell from a big, extinct terrestrial fowl with a demonic nickname. In 1981, researchers in Australia found the charred remnants of severa eggs from numerous cooking fires utilized by prehistoric humans, courting to approximately 50,000 years ago. Some of the eggs have been diagnosed as the ones of emus. But some outsized specimens belonged to a second, unknown chook. For years, scientists argued approximately the identification of that big fowl. But given the eggs' length and age, over time, two contenders emerged: Progura, a collection of big turkey-l...
