Katherine Hadley and Jonathan Leibovic, from Casey Dunn's Invertebrate Zoology (Biol 0410) course at Brown University, sing a song about tardigrades. They composed the song, performed it with friends, and made the animation.Visit creaturecast.org for more stories about the unexpected world of Biology.The hand-drawn animations were photographed at the Brown University Science Center (brown.edu/academics/science-center/).
