The family was named after Brísingamen, a necklace belonging to Freya from Norse mythology that was stolen by Loki and hidden in the sea.

[3] Members of this family have a small, Ophiurida-like disc, clearly demarcated from the arms, which number more than five.

There is an acute angle between them and they can be shed at the base where they are separated from the disc by a deep groove.

After a narrow cylindrical portion, the part of the arms closest to the disc accommodates the gonadal tissues and widens out somewhat.

They raise their arms vertically above their discs to filter feed on suspended organic particles drifting past.
