Here we see a Venus Girdle (Cestum veneris), but not in its typical shape. Normally, it’s unfurled into a long, slender ribbon, propelling itself via a network of tiny hair-like cilia that reflect & refract light into a rainbow of hues. They float around, mostly at the mercy of the currents, trapping tiny copepods & other tiny food bits. But why is this specimen coiled into a yin-yang spiral? The answer might be akin to, why does one human sit upright, while another sits with legs crossed, while another prefers to sit on the floor.
The total length of this Venus Girdle was about 20”, and coiled into this shape, it was about 2” diameter
