Creature Feature is an iHeartRadio production hosted by Katie Golden, who introduces herself as having studied psychology and evolutionary biology and, jokingly, as a host of many parasites. The show is about animals, and its episode titles show how far that reaches. Examples include 'I Just Had a Baby Rerun! Moo Deng! Pesto! Giant Babies!', 'Creature Classic: Evolution's Best Mistakes!' and 'What's Up With Skin?'. The titles are loud, often ending in an exclamation mark. The answers are more careful. The Moo Deng episode shows the show at its best. It greets the internet's favorite baby hippo and Pesto, an enormous, fluffy baby king penguin, with open excitement, and trades jokes about Fantasia's ballet hippos and Dance Moms. It also makes a serious point: a famous zoo animal is still a wild animal, owed respect rather than treatment as a pet, a toy or entertainment. Penguins come back in 'Creaturekringletimes: Chill Babies!', which describes fathers staying with the egg while mothers go off to bulk up and bring food back. It also covers male penguins pairing up to adopt abandoned eggs or chicks, something that has happened at zoos around the world, with Roy and Silo offered as probably the most famous couple. The caution here is typical. The episode notes that the examples it found were in king penguins and declines to confirm the same for emperor penguins, while calling it unsurprising given how closely related they are. 'What's Up With Skin?' brings in Dr. Kaveh Hoda, a medical professional who hosts the House of Pod medical podcast. Its premise is research suggesting humans are remarkably poor at healing wounds, set against an animal whose healing Golden describes as Deadpool-esque and bordering on the grotesque. Along the way the conversation jokes that cooperating and pounding one rock against another may be humanity's main talents. 'Creature Classic: Evolution's Best Mistakes!' goes much further back, to an ancient predator whose front appendages, lined with bristly spines, may have suited soft-bodied prey better than a struggle. Then there are the Listener Questions episodes. In 'Listener Questions: Bugs!!', a listener named Jesse C. asks about ants, cordyceps and bait traps, and the answer weighs slow evolution against learning. In 'Listener Questions: Do Fish Smell Fishy to Fish?', an answer on spotted hyena coats runs through age, nutrition and mites, then admits it found no evidence of a seasonal change, without ruling one out. For insects, start with the Jesse C. question; for the show's blend of silliness and conscience, start with Moo Deng.
