Last week, I learned about the upside-down jellyfish, of the genus Cassiopea, from Dr. Monica Medina (Penn State University).  Cassiopea has symbiotic algae in its tissues which helps the jellies get the nutrition they need. The Medina Lab has been using Cassiopea to study how host organisms interact with their symbionts throughout different stages in their life. Learn more about Cassiopea in today’s comic: jealous jellies

Check out the upside-down jellies in action and the cool work being done in the Medina lab!
