A massive invasion has taken over California's beaches, but it's not the typical scenario of beachgoers flocking to the coast for summer fun. Thousands of "By the Wind Sailors," a type of small, translucent jellyfish-like creature, have washed up on the state's shores, leaving beachgoers and scientists baffled. These gelatinous organisms, also known as Velella velella, are known to drift across the Pacific Ocean, carried by the wind and currents. As experts scramble to understand the sudden surge, beach enthusiasts are advised to exercise caution, as the creatures can still deliver a painful sting.
