As It Happens6:13More than 100 possible new marine species discovered in a single deepsea expeditionDuring a research expedition off the coast of Chile, Erin Easton says her colleagues were constantly showing her some amazing new sea creature they'd just discovered."It would just be, like, 'Erin, Erin, Erin, look!'" Easton, a marine scientist at the University of Texas Rio Grande Valley, told As It Happens host Nil Köksal."It is beyond my wildest dreams of what we could have expected. It felt like every time we went…

As It Happens6:05Spider webs catch more than prey. They're also jam-packed with animal DNAJosh Newton probably isn't very popular with spiders. After all, the Australian scientist has a tendency to go around undoing their hard work. "I liken it to when Princess Fiona in Shrek makes some cotton candy for Shrek from spider webs, where she collects a stick and just wraps around the spider web for him. But I do it with a clean, sterile stick," Newton, a PhD candidate in life sciences at Curtin University, told As It Happens…

Difference between Invertebrates and Vertebrates: Invertebrates and Vertebrates are two major groups of animal kingdoms based on the presence or absence of a backbone or vertebral column. Invertebrates make up about 97% of all animal species, lack a backbone and include diverse creatures such as insects, spiders, worms, molluscs, and crustaceans. On the other hand, vertebrates account for around 3% of the animal kingdom and possess a backbone made of bone or cartilage. This group comprises fish, amphibians, reptiles,…

They are related to snails and clams (mollusks), bristle worms, earthworms, and leeches (annelids), as well as ribbon worms…

We biological beings are messy things, leaving bits of our former selves behind everywhere we go – even in the air. This trail of self includes various secretions like saliva, discarded waste. and our constantly shedding outer layers like dead skin cells – many of which contain our unique DNA signatures.  Bugs are no exception. From spiders to beetles, invertebrates also leave a snail trail of evidence in their wake – including over any growing tea leaves they may have munched on or even just brushed by.Scientists have…
