With plural agreement: a small phylum of unsegmented marine invertebrates comprising the peanut worms, which are characterized by a swollen body and a retractile proboscis (introvert) that bears a terminal mouth typically surrounded by tentacles. Also: animals of this phylum (collectively or individually); peanut worms.Formerly called Sipunculoidea or Sipunculida, and once regarded as either holothurians or gephyrean worms, the Sipuncula are now sometimes placed in the phylum Annelida.

Hist. 7 457 (note) As it is now recommended that the termination ‘-oidea’ should be used only in connection with the names of superfamilies.., an alternative suffix is necessary. I propose, therefore, to follow the ‘Pearse’ system..by which the name of this phylum becomes Sipuncula.
