Solution

Hydra:

  1. Invertebrate freshwater animals of the genus Hydra belong to the class Hydrozoa (phylum Cnidaria).
  2. This organism has a thin, transparent tube for a body that can grow up to 30 millimeters (1.2 inches) long but can also contract significantly.
  3. Animals have a hollow, fluid-filled bodily chamber called the coelom.
  4. The digestive system and other organs are surrounded and contained by the coelom, which is located inside the body.
  5. Annelids, molluscs, and arthropods are examples.
  6. Some animals don't have any kind of body cavity. Semi-solid mesodermal tissues hold the organs loosely in the blastocoel.
  7. Flatworms, sponges, and other poriferans are examples.
  8. Hydra is an acoelomate animal.
