The zooids are soft bodied organisms with tentacles that live inside a cell that is part of the colony’s exoskeleton. The way these cells are arranged depends on the morphotype of the species.

Colonies of hydroids are typically 5 to 500 mm (0.2 to 20 inches) or more high and are branched; the branches bear the individuals, or zooids (hydroid polyps). Each zooid consists of a tubular body that has two layers separated by a thin jellylike mesoglea (layer of connective tissue), a terminal mouth, and surrounding circlet(s) of tentacles.zoans and such invertebrates as byrozoans and spiror- bid polychaetes (Harlin, 1980) also contributes sig- nificantly to the total productivity of eelgrass com- munities (McRoy and McMillan, 1977; Penhale, 1977).
