"Unveiling the Enigmatic Sea Creature: A Colony of Parasitic Worms or Alien-like Organisms?"

Researchers have identified a unique sea creature captured in underwater photographs taken in 2018 off the coast of Okinawa. The creature is actually two types of parasitic larvae worms, dubbed "sailors" and "passengers," that form a colonial organism. The sailors use their bodies like appendages, moving in unison to swim and navigate the water. The discovery sheds light on the cooperative behavior of these tiny organisms.
