Thousands Of Jellyfish-Like Creatures Wash Up On Pacifica Beaches

PACIFICA (CBS SF) -- The beaches in Pacifica were glimmering blue after thousands of jellyfish-like creatures washed up on shore earlier last week.

The creatures known as Vellela vellela are a close relative of the jellyfish, but don't sting.

They have a small sail that peoples them over the surface of the ocean, earning them the nickname 'By the Wind Sailor.'

When winds shift onshore, the creatures blow up onto beaches.
