The anemones—both of which are commonly called Tealia red anemones under the species of Urticina—spawned in late April and early May, just days apart. Henley collected the eggs and sperm from the more than 2,000-gallon tank and put them together in smaller tanks to increase the chances of fertilization. After fertilization, the larvae settled and metamorphosed into a polyp.

Breitburg and her team want to determine just how much stress they cause. Over the next five years they will conduct a series of lab and field experiments that examine how diel-cycling hypoxia and the associated acidification affects the growth and disease rates in striped bass, the eastern oyster and other ecologically and economically important Chesapeake Bay species. They will also study the animals’ behavioral responses to these changes.
