Oraciones de ejemplo
  • The groups Hydrozoa, Scyphozoa and Cubozoa all are generally characterized as having polyps and medusae (although minor lineages have lost medusae and in some cases polyps).
  • Another feature that is quite common in Hydrozoa but not typical of Scyphozoa is colonial organization.
  • However, Hydra is not typical of the Hydrozoa as a whole.

Origen

Modern Latin (plural), from hydro- 'water' + Greek zōion 'animal'.
