Understanding Iridoviruses and Structural Color

The video explores terrestrial isopods, commonly known as rolly pollies, and their unique color changes caused by iridoviruses. These viruses infect various ectotherms, leading to structural color changes due to the arrangement of viruses in cells. The video explains the difference between patent and covert infections and their ecological impacts, including potential roles in colony collapse disorder. It also discusses the potential for using iridoviruses in pest control. The video concludes with a Skillshare sponsorship, promoting their educational classes.
