The Peninsula Daily News reports Monday that sea stars at Port Townsend's Marine Life Center and Feiro Marine Life Center in Port Angeles have died of the disease, known as sea star wasting.
In Port Townsend, 12 ochre stars have died, while it eliminated a species from the tanks in Port Angeles. Both centers pipe in ocean water for their tanks.
Experts believe the disease may be caused by bacteria or virus and that it's infectious.
Caretakers at the Peninsula's marine science centers don't intend to replace sea stars until they feel more confident they can keep them alive and to avoid taking breeding adults that may be needed to replenish wild colonies.
