Strange blob-like sea creatures washing ashore across Southern California coast

(KTLA) – Bizarre sea creatures that resemble jellyfish have returned to Southern California waters a year after millions were spotted between Ventura and San Diego counties and beyond.

Velella velella, more commonly known as by-the-wind sailors, are oval-shaped blobs that live on the ocean's surface, propelled by small, stiff sails that catch wind and take them across the globe. Ocean currents and winds move the creatures from place to place, allowing them to catch their prey with their stinging tentacles.
