The Smallest Stars Have Gone Out

Feb 12, 2020

More than 20 species of sea star suffered in a disease outbreak that started in 2013. But in the Bay Area, one small star hasn't returned.

Once there were thousands, a galaxy of tiny stars strewn over the rocky beaches of West Marin and the San Mateo coast. But within only a few years, Leptasterias pusilla, or the six-rayed sea star, vanished from Bay Area coastal beaches.

Researchers uncover clues to sea star disease

Jan 21, 2020

All along North America’s West Coast, sea stars are vanishing. The colorful invertebrates are falling victim to one of the largest epidemics ever seen in the ocean: a mysterious plague known as sea star wasting disease. A new study by researchers in the lab of Professor of Biology Sarah Cohen delves into the dramatic decline this disease has caused in Leptasterias — also known as six-rayed sea stars — around San Francisco Bay.

Study shows potential for a sea otter resurgence in SF Bay

Dec 20, 2019

Research by EOS Center scientists suggests otters could thrive in wetlands like those in the Bay Area.

San Francisco Bay has seen a recent resurgence in marine mammal species, and new research by a team including San Francisco State University scientists suggests that there might be room for one more. Sea otters, the study shows, would find widespread food and habitat in the Bay — and could perhaps spread to other estuaries, too.
