Giant purple sea slugs slime San Francisco Bay Area beaches
Source: AP
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.

(79 posts)I remember how, from a distance, the beaches at Catalina Island appeared to be BRIGHT red.
Only when you got close enough could you see it was actually a gazillion small, scrambling pelagic red crabs -- make that small, scrambling DELICIOUS pelagic red crrabs.
It looked like this pic taken in Australia (h/t photographer Phillip Colla, oceanlight.com):

My kid's "animal alphabet"--some Australian singer made it--had "N is for nudbranch!"

(9,688 posts)Pretty common animal, native to Pacific coast,ranges from far northern California to Baja; and used in neurobiology research.
A little weird to see them in SF Bay-- ordinarily, SF Bay is slightly reduced in salinity, and I think of them as rocky-shore, open-ocean type critters.
So maybe this is about the drought.Because of drought, SF Bay hasn't been getting as much fresh-water input, and salinity is probably closer to regular -ocean salinity than usual. Which means that "regular" marine critters would start to establish themselves in SF Bay, not just the outer ocean coast.
Fun to watch them munching on seaweed: they kind of remind me of sheep (OK, purple slimy sheep)

(6,476 posts)That and the zoo were favorite haunts of mine back in the day. I had no idea...I imagine it changed the whole nature of the place, or am I wrong?
Thanks Bro Buzz

even without an El Nino, this was the case.
they cooled to near normal for April and May, but interestingly enough, at the end of may have been hovering around 60F, when normally they are in the low 50's.
it's not just the warmer ocean to consider, but the cause, a lack of upwelling of cold, deep ocean water to the surface, which cools our coastline considerably.
this upwelling not only cools the ocean, but it brings nutrient rich waters from the deep.
a lack of this stuff is worth exploring the effects of.
