This species is a model organism for the lophotrochozoan group (including Phylla as Mollusca, Annelida and Trematoda).

P. dumerilii presents several advantageous features:

  • It can be bred in the laboratory
  • Exhibits an ancestral-type body plan
  • Displays indirect development through a ciliated trochophora larva
  • Produces several thousands of offspring in this singular act of spawning

(Arendt et al. 2001)

Contain more complete set of ancestral urbilaterian genes and cell types and a less complex development and morphology that can be more easily studied. Model organisms in research (especially in Developmental Biology and Ecotoxicology).
