While exploring the Chile Margin along South America’s coastline, researchers made a dazzling discovery with their robotic explorer, ROV SuBastian: the iridescent ‘sassy sparkler‘ sea worm.
At first glance, this deep-sea polychaete worm appears unremarkable with its bristly body. But as it moves, its shimmering bristles reflect light, creating a pink iridescent glow. The secret lies in nanoscale structures within the bristles that act like prisms, scattering light to produce shifting colors depending on the angle of view.
This optical illusion not only mesmerizes but also serves practical purposes. The worm’s changing hues help with camouflage, communication, and UV protection in the deep ocean.
Polychaetes like the ‘sassy sparkler’ play essential roles in marine ecosystems, thriving in extreme environments like hydrothermal vents and contributing to nutrient cycling in ocean depths.
