A mysterious disease called sea star wasting syndrome decimated 95% of the sunflower sea star population in 2013. Since then scientists have been working to learn more about the disease and figure out ways to save the sunflower sea star from extinction.
For the first time, researchers with the San Diego Zoo Wildlife Alliance’s reproductive sciences team, in collaboration with Sunflower Star Laboratory and Dr. Jason Hodin, senior scientist at Friday Harbor Laboratories were able to hatch dozens of baby sunflower sea stars using cryopreservation technology.
Cryopreservation is the process by which live tissues and cells are frozen in order to keep them for an extended amount of time. In this case, the researchers successfully froze sunflower sea star sperm, thawed it and fertilized eggs that developed into larvae.
According to Nicole Ravida, laboratory manager for San Diego Zoo Wildlife Alliance, “Cryopreservation is one method reproductive scientists can contribute to the preservation of gene diversity in sunflower sea star populations.”
The researchers believe maintaining gene diversity is the best way for sea stars to adapt to future stressors.
