Why anteaters keep evolving, and how giant whales get enough food to live

Why anteaters keep evolving, and how giant whales get enough food to live

First up on the podcast, Online News Editor David Grimm brings stories on peacock feathers’ ability to emit laser light, how anteaters have evolved at least 12 times, and why we should be thanking ketchup for our French fries. Next on the show, rorqual whales, such as the massive blue whale, use a lunging strategy to fill their monster maws with seawater and prey, then filter out the tasty parts with baleen sieves. Lunging for food when you weigh 100 tons seems like it would be an energetically expensive way to meet your dietary needs. But as Ashley Blawas, a postdoctoral researcher at the Hopkins Marine Station at Stanford University, describes in Science Advances this week, lunge-feeding whales have a few tricks up their sieves and use much less energy than predicted. This week’s episode was produced with help from Podigy. About the Science Podcast Authors: Sarah Crespi; David Grimm Learn more about your ad choices. Visit megaphone.fm/adchoices
