ALAMEDA, Calif. (AP) — A giant purple blob from the sea — a slug — is invading East Bay beaches and waterways this summer, and some experts say it may be caused by warmer temperatures near coastal waters.
These California sea hares are harmless plant eaters. But their big size and unusual abundance this year is turning heads at the shorelines in the cities of Crab Cove in Alameda and Miller Knox Regional Park in Richmond, as well as Lake Merritt in Oakland and Tomales Bay in Marin County, the Contra Costa Times reported Saturday (http://bayareane.ws/1IRy5ej ).
"We are getting calls from the public asking what the heck is this big weird purple blob," said Carolyn Jones, a spokeswoman for the East Bay Regional Park District. "It's native to our area. It's not endangered, but they are rarely seen other than an occasional one here or there."
Officials have no precise count, but dozens have been seen on some beaches at the same time, and two dozen were spotted last month in an inlet to Lake Merritt in Oakland.
