Definition of Priapulida in English:

Priapulida

plural nounˌprʌɪəˈpjʊlɪdəˌprīəˈpyo͞olədə

Zoology

A small phylum of burrowing wormlike marine invertebrates that have a thick body, a large eversible proboscis, and a terminal tail.
〔动〕曳鳃动物门
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.

Derivatives

priapulid

adjective & noun prʌɪˈapjʊlɪd

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.
