Clearing and Staining Fishes

Diaphonization -- otherwise known as clearing and staining -- is one of the most photogenic preparation methods used by research scientists. It's beautiful, but is it practical? We interviewed Dr. Caleb McMahan, Collection Manager of Fishes, on how he uses this technique to answer questions about the evolution of fish! To learn more about what's happening in Fishes at The Field Museum, check out their webpage: https://www.fieldmuseum.org/science/r... Big thanks to Caleb for taking the time to share his work with us, and to Alan Resetar for lending the reptile and amphibian specimens!... as well as the extra light table because ours broke right before filming. :( ---------------------------------------­---------------------------- Come hang out in our Subreddit:   / thebrainscoop   Twitters: @ehmee Facebook:   / thebrainscoop   Tumblr: thebrainscoop.tumblr.com ---------------------------------------­---------------------------- Producer, Writer, Creator, Host: Emily Graslie Producer, Editor, Camera, Graphics: Brandon Brungard ---------------------------------------­---------------------------- Filmed on Location and Supported by: The Field Museum in Chicago, IL (http://www.fieldmuseum.org)
