Brine Shrimp and Dormancy

The video discusses the fascinating ability of brine shrimp, specifically Artemia, to survive in a dormant state for years. These creatures can pause their metabolism and become cysts, allowing them to withstand extreme conditions. A study showed that a significant percentage of these cysts can hatch after years without oxygen. The video also compares this dormancy to other animals and highlights the unique self-sufficiency of Artemia. Additionally, the video is sponsored by Brilliant, an online learning platform.
