The California coast is currently experiencing a rare natural event, as thousands of by-the-wind sailors, scientifically known as Velella velella, are washing ashore. This phenomenon, which creates stunning blue carpets on the beaches, results from specific ocean currents and seasonal wind patterns.
Mass strandings of by-the-wind sailors have been occurring for millions of years, influenced by changing ocean conditions. Marine biologists note that this year’s conditions have notably led to a bloom of these small marine animals along the coast.
Key facts:
- Thousands of by-the-wind sailors are washing up along California beaches.
- They possess a flat, oval body and a sail-like structure that allows them to drift on ocean currents.
- By-the-wind sailors are not dangerous to humans; their stingers are designed for capturing plankton.
- Once stranded, they cannot survive out of water for long and will dehydrate quickly.
According to sources, while the sight may appear dramatic, it is a natural part of their life cycle. Steven Haddock, a marine biologist, emphasized that although people may have never seen such an abundance of jellylike creatures on the beach before, it should not cause alarm.
He further explained that what washes up is typically what one would find attached to rocks or other surfaces on the seafloor. However, Haddock cautioned that within a couple of weeks, these organisms will likely become desiccated and blow away like fragile pieces of rice paper.
