Feathery gills! Adorable smiles! Cultural icons! Habitat ecology! And superhuman limb regeneration? It\u2019s an entire episode on axolotls. You either love these aquatic salamanders, or you\u2019ve never heard of them. Clap your tiny slimy hands for Ambystomologist Dr. Jessica Whited of Harvard Medical School\u2019s Stem Cell and Regenerative Biology who raises and studies these beautiful creatures \u2014 including the biomedical marvels being discovered. Also discussed: their narrow niche, the ecology movement to save them from wild endangerment, pet care ethics, color morphs, green glowing genetically modified ones and so much more. And of course: Minecraft.
