    Example sentencesExamples
    • The oldest known ‘aschelminth’ phylum is the Priapulida.
    • The fine structure of the mouth cone, the introvert with scalids, and the circumenteric brain indicate that this meiofaunal phylum is monophyletic, related to Kinorhyncha and Priapulida.
    • They concluded that Gastrotricha is the sister-taxon of a monophyletic clade comprising Nematoda, Nematomorpha, Priapulida, Kinorhyncha and Loricifera.
    • Loricifera, Priapulida, and Kinorhyncha are unequivocally assumed to be most closely related and are, therefore, united in one group, named Scalidophora first by Lemburg.
    • The phylum Loricifera shares many apomorphic characters with both Priapulida and Kinorhyncha, and can be included in the taxon Scalidophora, a subgroup of Cycloneuralia.

    Zoology
    • If this evolutionary interpretation is correct, this change in behavior marks the origin of infaunal priapulid worms from those crawling at the sediment surface with ventral appendages.
      Example sentencesExamples
      • Over twenty species of non-mineralized arthropods have been found in the Wheeler Shale, as well as annelids, priapulids, and other worms, and the swimming predator Anomalocaris.
      • Such morphology is consistent with that of priapulids, known to burrow in the early Cambrian clay and sand.
      • Instead, some pseudocoelomate animals, such as priapulids and nematodes, appear to be more closely related to arthropods, in a group termed Ecdysozoa.
      • Most, if not all, of those infaunal traces of activity were produced probably by relatives of priapulid worms.

Origin

Modern Latin (plural), from Priapulus (genus name), diminutive of Priapus.
