 It fed on sea-floor mud, evidenced by the frequent presence of sediments preserved in its gut.Along with the other Cambrian priapulids "Ottoia", "Selkirkia, Louisella", "Ancalagon", "Scolecofurca", and "Lecythioscopa", the organism was originally classified into a clade termed the archaeopriapulida, a stem group to the Priapulids proper.However, the morphological similarity of these organisms to their modern cousins is remarkable, especially for the Burgess Shale, and their similarity to the modern genus "Maccabeus" suggests that they are in the Seticoronaria stem group, and thus are true crown-group priapulids.
