On this episode, Casey talks about an organization working to protect cotton-top tamarins in Columbia, and I share a story about 'mini kangaroo on steroids' making a comeback in south Australia. We learn about our Favorite Marine Animal Not Already Covered on the Podcast, the Blue Blubber Jellyfish and the West Indian Manatee, and about our Animal of the Week, the Iberian Ribbed Newt.
