释义

Mesozoa

/ˌmɛsə(ʊ)ˈzəʊə/
Zoology
noun
Treated as plural: a group of minute worms with no body cavity or organs other than reproductive cells, which are internal parasites of marine invertebrates and absorb dissolved nutrients directly from the host's tissues; (also mesozoa) worms of this group collectively.
  • The Mesozoa were so named as being supposedly intermediate in structure between protozoans and metazoans. The group has traditionally been treated as a phylum, and latterly as two related phyla, Orthonectida and Rhombozoa..

Origin

Late 19th century; earliest use found in Quarterly Journal of Microscopical Science. From meso- + -zoa, after French Mésozoaires.
