What ARE Those Blue Blobs on San Diego Beaches?
Velella velella, which are fairly common, enter the scientific record in 1758. The critters, which at maturity, reach about 3 or 4 inches in diameter, are commonly seen off the coast of California
“Anytime we have jellies on the beach… I always say for people to observe with their eyes and not their hands because it’s really challenging for someone to know how to identify these from, say, another type of purple-looking jelly that could sting and hurt you.”
