The species was described from British Columbia and California and placed in a new genus and family since it did not have the stomach and sex organs in the usual structure known as the calyx but in a sac at the base of the stalk of its worm-like body that is no smaller than 2 cm in length when fully developed.

The mouth is a squarish bone with which the jaw jointed in a similar way as the incus of the middle ear in mammals; its lips frilled with tiny hairs.

It has eight adjacent capitate tentacles that are located near the calyx, which is short with no arm lobes.

The calyx contain the stomodeum(the embryonic anterior ectodermal part of the digestive tract.)

The most common color for this animal is purple with white spots around the calyx.
