Efforts to restore coral beds by returning oyster shells to reefs may be making an impact — but not for sea stars. Plagued by star wasting syndrome in 2013, the majestic creatures saw an uneasy population decline. However, a miraculous turn of events has seen the distinguished species resurface in Southern California.
“It’s a huge difference… A couple of years ago, you wouldn’t find any. I dove all the way as far as Canada, specifically looking for sea stars, and found not a single one,” … said Darryl Deleske, an aquarist at San Pedro, California’s Cabrillo Marine Aquarium.
While die-offs have occurred in the 70s, 80s, and 90s, climate change has amplified its latest comeback. With no solid explanation to star wasting syndrome, the disease is tricky. Still, researchers have offered a number of theories.
Scientists suggested that parvovirus, which can be carried by other invertebrates, might be linked to the disease, with the viral agent possibly “going rogue.”
The sea star’s resurgence may be a conundrum even the Mystery Gang can’t solve — but a fortunate one at that!
