What ARE Those Blue Blobs on San Diego Beaches? NBC 7 San Diego
Visitors to the strand in Pacific Beach may notice some unusual visitors on the sand this week.
NBC 7 got some photos of our newest sea creature friends what scientists call “pelagic colonial hydrozoans,” aka By-the-Wind Sailors or Velella velella from a sharp-eyed Pacific Beach-goer who was out walking Monday morning.
These blue Mondays, which are unable to deliver a sting that humans can detect, have been spotted north recently, reportedly in Huntington Beach and farther up the coast, but the local sighting was the first we heard of in San Diego County.
I have not seen them but I believe it.
