Physical description
Adults have a body length of approximately 9 mm. The animal's head includes two pairs of tentacles, one set of labial tentacles and another set of rhinophores, both sets of which are cylindrical, solid, and taper at their tips. The eyes are located just behind the rhinophores. The animal's creeping foot is three times the width of its head and tapers to a point at the posterior of the animal. The anterior end of the foot also has a pair of propodial tentacles. The animal's head is brown, and the tentacles and foot are semi-translucent. A distinct black stripe extends from the dorsal part of the cephalic tentacles and proceeds to the end of the animal's foot. The body includes a transparent notum which is free and oval-shaped. The notum is as wide as the foot and extends well over half of the body length. Some of the internal organs can be viewed through this structure. The mantle and foot are also covered in small granular white spots. There is no shell, no gills, and no mantle cavity. The animal is able to partially retract its head beneath the notum when disturbed.
