Living Together - Parasites and Hosts

In this video, zoologist Dr. Anna Phillips shares the importance of parasites and how they relate to their hosts.

Description: 

Meet Dr. Anna Phillips, a zoologist at the National Museum of Natural History. Did you know that parasites are some of the most abundant members of ecosystems? They make up as much as 60 percent of the biomass, and have complex relationships with the host organisms they depend on. See what Anna discovers from studying how parasites such as leeches and tapeworms relate to their hosts. Consider the significant roles parasites play in our lives and the ecosystems we inhabit. Gain a new perspective on parasites. This show aired May 19, 2016.
