The California coast is experiencing a rare natural event with thousands of by-the-wind sailors washing ashore, creating stunning blue carpets on the beaches. These small marine animals, known scientifically as Velella velella, have been spotted along the coastline since early May.
Mass strandings of by-the-wind sailors are not new; they have occurred for millions of years, influenced by ocean conditions and seasonal wind patterns. This year’s conditions have led to a noticeable bloom along the coast, captivating beachgoers and marine enthusiasts alike.
Key facts:
- By-the-wind sailors are small marine animals with flat, oval bodies and sail-like structures that allow them to drift on ocean currents.
- They are harmless to humans; their stingers capture plankton, not people.
- Once stranded, they cannot survive out of water for long and will dehydrate quickly.
Marine biologists have noted that these mass strandings can look dramatic but are a natural part of their life cycle. Steven Haddock, a marine biologist, emphasized that while people may find the sight alarming — given the sheer number of jellylike creatures — it’s really not cause for concern.
He added, “Within a couple weeks, they will probably be desiccated and just blow away, like a piece of rice paper.” Observers are keenly watching how this event unfolds in relation to local marine life. By-the-wind sailors serve as an important food source for larger marine animals such as sea turtles and ocean sunfish.
