The Milky Ribbon Worm is a long, milky or creamy white colored worm. They can grow up to 106 cm. Males turn red during the breeding season, while females take on a brownish tint.

Habitat

C. lacetus live under rocks and in the sand of shallow water areas. However, they can swim from place to place in a side winding snake-like motion.

Feeding 

C. lactues impale their prey with their proboscis; they eat small organisms in the water column.
