Color: The body is pink, the lophophori are transparent with pigment spots.
The lophophorae are horseshoe-shaped with medially turned ends, up to 160 tentacles with a length of 2-3 mm.
Nephridia with a single funnel (usually surrounded by nephridial epithelium during the reproductive period).

Sexual reproduction: Females release their eggs into the surrounding seawater, where they are fertilized by males with large glandular lophophor organs.
